WiFi and Network Configurations for 3Gbps/5Gbps/6Gbps/10Gbps plan

[xiaofan]

1. Singtel has some updates in the 3Gbps/5Gbps/10Gbps FAQ which are worth reading if you are considering Singtel Fibre Internet services (using ONR).

3Gbps: with HB611-SGST WiFi 7 router (recommended) or Singtel AX5400 device (not recommended)
https://www.singtel.com/content/dam...ments/fibre-3gbps-enhanced-plan-faq-setup.pdf

5Gbps: with HB611-SGST or HB810
https://www.singtel.com/content/dam...ments/fibre-3gbps-enhanced-plan-faq-setup.pdf

10Gbps: with HB810 (recommended if you want to "fully utilize the available bandwidth) or HB611-SGST
https://www.singtel.com/content/dam...ments/fibre-3gbps-enhanced-plan-faq-setup.pdf

2. Example from the 10Gbps FAQ
1) Singtel 10Gbps plan with HB810

You can "fully utilize the bandwidth" with a 10Gbps capable wired device.

If you do not have a 10G wired device, it is still possible to saturate the 8.2Gbps bandwidth provided by the 10Gbps Fibre internet service

2.5Gbps x 2 + 1Gbps x 3 + wireless = 8Gbps + wireless (Nokia XS-240X-A only has three 1GbLAN ports)
2.5Gbps x 2 + 1Gbps x 4 + wireless = 9Gbps + wireless ( ZTE F8648P ONR has foud 1G LAN ports)

2) Singtel 10Gbps plan with HB611-SGST -- you will not be able to "fully utilize the bandwidth" if you feel that is important (to most of the users it is probably not so important).

You can see that you can utilize only up to 2.5Gbps + 1Gbps x 3 = 5.5Gbps from the 10Gbps Fibre Internet plan.

3. Example from the 5Gbps FAQ
1) Singtel 5Gbps plan with HB810

You can "fully utilize the bandwidth" with a 10Gbps capable wired device.

If you do not have a 10G wired device, it is still possible to saturate the 8.2Gbps bandwidth provided by the 5Gbps Fibre internet service, with just two x 2.5G wired device plus wireless.

2) Singtel 5Gbps plan with HB611-SGST

You can see that you can fully utilize the 5Gbps bandwidth with one 2.5Gbps wired device (connected to the HB611-SGST) pluse three 1Gbps wired debice (connected to the ONR).

(Note the colour is wrong for the 2.5Gbps connection.

Which 10Gbps plan do you recommend? I guess it depends on the hardware that they are offering.

Starhub: TP-Link EB810v router

M1: ASUS ZenWiFi BT10 (Pack of 2) OR TP-Link Archer BE805
Singtel: Singtel WiFi 7 router (BE11000), not sure which TP-Link model is this

I do not recommend 10Gbps plan but rather M1 6Gbps (S$34.90 per month with free Archer BE805) or Starhub 5Gbps plan (S$29.55 per month with free HB710). But that is just my personal opinion.

You can read the comparison in the sticky thread on top of this forum section and come to your own conclusion.

BTW, Singtel BE11000 router is a lower end HB611-SGST, which is not 10Gbps capable, but rather only 2.5G capable. Singtel has some 10Gbps plans which come with HB810 which is 10Gbps capable.

For 10Gbps, is it better to go with Archer BE805 or Asus BT10? I am using Asus AX6000 at the moment and intend to keep it as access point to run legacy devices.

Update Post #7 to include Singtel specific information.

5. Singtel is really bad in terms of free wireless routers given for the 3Gbps/5Gbps/10Gbps plans, especially the cheaper base plans.

Look at Starhub:
3Gbps plan --> ONT + HB410 (2.5G capable, dual 2.5G ports and dual 1G ports, dual band BE6500)
5Gbps plan --> ONT + HB710 (10G capable, dual 10G ports, triband BE18000)
10Gbps plan --> ONT + mostly EB810v (10G capable, dual 10G Ports, three 2.5G LAN ports, triband BE22000), some plans with HB710.

Look at M1:
3Gbps plan --> TP-Link Archer BE230 (2.5G capable, dual 2.5G ports, three 1G ports, dual band BE3600)
6Gbps plan --> TP-Link Archer BE805 (10G capable, dual 10G ports, four 1G ports, triband BE19000)
10Gbps plan --> Asus ZenWiFi BT10 two-pack (10G capable, dual 10G ports, one 1G port, triband BE18000) or single Archer BE805 [most of the users should get Asus ZenWiFi BT10 two-pack as the resale value is at about S$660 to S$700; Archer BE805 resale value is at about S$270 to S$300]

Now look at Singtel (all with XGS-PON ONR).
3Gbps plan --> Singtel AX5400 or HB611-SGST. Only HB611-SGST (2.5G capable, dual 2.5G ports, dual 1G ports, triband BE110000) is a good match for 3Gbps plan.

5Gbps plan --> Singtel AX5400 or HB611-SGST. HB611-SGST (only 2.5G capable) is not that good match for 5Gbps plan already but anyway still much better for Singtel AX5400.

10Gbps plan --> still HB611-SGST or HB810 (dual 10G ports, dual 2.5G ports, triband BE22000). Only HB810 is a good match for 10Gbps plan. HB611-SGST is really not a good match.

6. Singtel 10Gbps WiFi 7 FAQ
https://www.singtel.com/content/dam/singtel/eshop/Fibre/agreements/10Gbps-FAQ-WiFi7.pdf

Only the HB810 option can have the possibility of "fully utilizing the given 8.2Gbps bandwidth". You only need one 10G wired device to saturate the bandwidth.

The HB611-SGST diagram can only utilitze up to 5.5Gbps bandwidth (1 x 2.5Gbps + 3 x 1Gbps).

7. Singtel 5Gbps FAQ:
https://www.singtel.com/content/dam/singtel/eshop/Fibre/agreements/5gbps-faq.pdf

Technically all diagrams can utilize the 5Gbps bandwidth. But the two HB611-SGST based connection scheme wil require four wired device to saturate the bandwidth (1 x 2.5Gbps + 3 x 1Gbps). HB810 based connection scheme only needs one 10G wired device to saturate the bandwidth.

Alternative way for ONT based solution
ONT + wireless router + 10G/2.5G or 10G capable switch --> 10G/2.5G/1G Wireless AP
ONT + wired router + 10G/2.5G capable switch --> 10G/2.5G/1G Wireless AP

For power users, the wired router can be PCs running pfSense/OPNsense/OpenWRT/etc, or Ubiquiti 10G capable Gateways, or MikroTik 10G capable routers.

You can treat Starhub Nokia XS-2426X-A as "ONT + Wireless router". You can also treat Singtel/WC ZTE F8648P ONR as "ONT + wired router". However, with the ONT, you have the flexibility to choose the wireless or wired router to use, depending on your budget and use cases. The ONRs will usually have limited features.

ONT vs ONR:
https://forums.hardwarezone.com.sg/...cs-of-home-networking.6653421/#post-138363236

Example from Starhub:

Same as above but the main router changed to EB810v.

For those who get two HB710 initially but later want to have more wired devices (2.5G). In that case, they can add a 2.5G/10G switch. But it is easier to have the EB810v from the very beginning and then no need the 2.5G/10G switch.

I have a dumb switch like a setup above, is it better for the eb810v stays inside DBBOX or it’s better i utilise it in the living room? will the signal stronger than the HB710? Meaning to say my HB710 will be the main node inside db box and the 2nd 10GBps port will be connecting to 10gbps dumb switch, then my patch panel to rooms can be all 10gbps ready. Since HB710 has only 2 ports i think its better to stay inside DBbox rather than in the living room as mesh?

Appreciate your advice from all the experts here

1) ISP Typical Wireless Configuration -- Singtel/WC with ONR

Relevant info from Singtel.

Singtel XGS-PON ONR for 3Gbps/5Gbps/10Gbps plan

• ZTE F8648P ONR, 10G capable wired router, with one 10G LAN port and 4 x 1G LAN ports
• Nokia XS-240X-A XGS ONR, 10G capable wired router, with one 10G LAN port and 2 x 1G LAN ports

Singtel wireless router, usually configured by Singtel in AP mode (or as mesh nodes if you have two nodes).

• Wi-Fi 6 Mesh Extender (WE620242-ST) --> not a router, AP or mesh node only, 1Gbps only, WiFi 6 AX5400
• Wi-Fi 6 Mesh AP5690W --> not a router, AP or mesh node only, 1Gbps only, WiFi 6 AX5400
• Wi-Fi 6 Router RT5703W --> only function as a router with legacy Singtel ONT, not working with other ISP's ONT, working as an AP when connected to the Singtel ONR or other ISP's main router, 1Gbps only, WiFi 6
• Wi-Fi 6 Router (WG660242-ST) --> only function as a router with legacy Singtel ONT, not working with other ISP's ONT, working as an AP when connected to the Singtel ONR or other ISP's main router, 1Gbps only, WiFi 6 AX5400
• Singtel WiFi 7 Router (HB611-SGST) --> function as either a router or AP, 2.5Gbps capable, triband WiFi 7 BE11000, dual 2.5G ports and dual 1G ports.
• TPLink HB810 Wi-Fi 7 Router --> function as either a router or AP, 10Gbps capable, triband WiFi 7 BE22000, dual 10G ports and dual 2.5G ports.

It is a shame that Singtel still offers the 1Gbps capable Wifi 6 router or mesh solution with some 3Gbps and 5Gbps plans.

So it is actually an improvement now they start to offer HB611-SGST for some 3Gbps and 5Gbps plans. But again it is shame that they offer HB611-SGST with some 10Gbps plans. Only the more expensive 10Gbps plans come with HB810.

1) 10Gbps plan with either HB810 or two x HB611-SGST (wireless backhaul).

2) 5Gbps plans with different setup

3) 3Gbps plan with different setups.

Those WAN Port only 1Gbps, next the Lan ports too. What a waste of 3 & 5 Gbps speed; it's like self-throttling or bottlenecking.

 

[1 Ghz]

320Mhz Wifi channel with 1Gbps wired mesh is silly. I'm pretty sure 160Mhz channel can exceed 1 Gbps.

Take note they only mention 320MHz channel bandwidth for HB611-SGST (triband BE11000, 2.5G WAN and 2.5GbLAN) and HB810 (triband BE22000, 10G WAN and 10G LAN).

For those WiFi 6 AX5400 wireless device, they mention 160MHz channel bandwidth.

But you are right that in some configurations mentioned in the SingTel FAQs, HB611-SGST's 2.5G WAN port may be connected to ONR 1G LAN ports and then 320MHz channel bandwidth is not so useful.

When the HB611's 2.5G WAN port is connected to the ONR's 1G LAN port, using 320Mhz channel is a waste. It's better to get a 2nd AP and run both at 160MHz on different channels for better coverage. Even with a single AP, using narrower channel means potentially less interference.

Starhub: TP-Link EB810v router

M1: ASUS ZenWiFi BT10 (Pack of 2) OR TP-Link Archer BE805
Singtel: Singtel WiFi 7 router (BE11000), not sure which TP-Link model is this

I dun have exp with other telco, i use MR but i personally prefer no router/ bring ur own router 10G plan , because most of their consumer routers are not that good.

For high efficiency,total control and cost effectiveness, I'd recommend virtualized router OS ( or CHR).

For reference, below is the performance when i do bandwidth test to a local test server
- The router is a vm on proxmox , i gave it 8 core , passthrough x710 nic from ms-01
- 8 core spread the load efficiently via virtio. Basically 1 core = 1 addition virtual ethernet. You can see each virtio share the load in screenshot
- 8 cores probably is overkilled for 10G network, 4 core is enough

- The test is done when all fiirewall rules activated.

Test to MR server is good too, i set to run speedtest every hour for past 3 months ( ignore the assymal 1.x Gbps , its expected when i tried some weird config lol)

With a help of good L3 switch ( i used CRS309) , its easy to saturate 10G connections in both Lan and Wan at the same time too.
1 downside is configure mik could be difficult for first timer , it requires certain network knowledge but its worth the effort. RouterOS gave us back the joy of learning network back in the day, it gave you total control of the device ( if you want to put in stupid config, it wont stop you lolz)

Hi, I am considering moving to 10GBE both internet and local networking. Here is my plan. Looking for feedback and ways I could do better. My priority is network stability > performance > cost.

Current Setup

My home is currently wired with CAT6 and there are RJ45 ports in every room. As the home is not large (around 1500 sq ft / 140 sqm), I think CAT6 will suffice as I don't expect cable runs beyond 40m.

My current setup is a bunch of Asus XT8s and 1GBE switches. Wired backhaul only. Around 40 connected devices. Performance has been rock solid. I am on MyRepublic 1gbps with fixed IP and it has been solid too.

I have a 10GBE ready Synology NAS which handles a fair bit of work from backups, cloud storage, media (Plex, Roon), etc. I might get a second Synology NAS in the coming year and it will be equipped with 10GBE too. My preference is to go SFP+ over RJ45 for both NAS (to reduce heat).



Intended 10GBE setup

ISP/Router
- Intend to go with Asus BT10 and M1's 10gbps plan seems to tick all the boxes.
- ISP wise, I am using MyRepublic's static IP to get around CGNAT issues (when hosting Roon Arc). My understanding from the ISP thread is that M1 does not use CGNAT, so I should be safe. (But do let me know if my understanding is off.)
- I've read that the BT10's stability issues have largely been addressed over the past year. But do sound out if there are still major stability issues. I had considered BQ16 but I think it is overkill.
- Cost wise, I had considered getting a 2-pack BT10 for around $600-700 on Carousell and pairing it with a no frills 10gbps broadband service. But I have not found a combination where the total cost is below M1's offer. (M1's total cost is $1221.60 (24 months x $50.90; 2x BT10s free). For a competing 10gbps plan to beat M1, the monthly subscription for 10gbps must be $25.90 or below. Do let me know if something like this exists. Do also flag if M1 10gbps has major stability issues.

Switch @ DB box
- Currently using a simple 8 port 1GBE switch (all ports are in use to connect the entire home).
- Intend to go with TP-Link TL-SX1008 (https://www.tp-link.com/sg/business-networking/soho-switch-unmanaged/tl-sx1008/)
- Reviews indicate it is stable. Performance and heat is ok. Fan can be noisy but my DB box is outside my home so the noise is ok.
- Cost is around $315 on Amazon.sg (Bizgram). Think it is reasonable.

Switch @ Rooms
- Currently using simple 2x 5 port 1GBE switches (1 room each; all ports utilised). These will serve 2x Win 11 PCs and 2x NAS
- Intend to go with 2x UniFi USW-Pro-XG-8-PoE. It appears overkill but the main reason for picking this is because I would prefer to go with SFP+. I understand that SFP+ runs much cooler than RJ45. These switches will sit in non-ventilated cabinets. I need them to run as cool as possible and at low noise (they will be in spots like under desks, close proximity to users).
- Connections between these two switches, the 2x PCs and NASes will all be SFP+. This means I need a switch that has 2x SFP+ and 2x RJ45 (to connect to wall port and a BT10 unit or a separate 1GBE switch).
- I understand there are other options but the field is quite murky. I am not comfy buying from AliExpress. Stability is my top concern so I would like something tried and tested. The Pro XG 8 PoE has had good reviews including stability, heat and performance. There is a fan but according to DongKnowsTech it runs silent after boot up.
- Cost is around $560 each, which is borderline high. But I have not been able to find an alternative that has 2x SFP+, 2x RJ45, stable, performs well at low heat and noise. Do let me know if there is something else. I do not need PoE.

PCIe cards for PCs
- I intend to add 10GBE SFP+ for my 2x Win 11 PCs. No obvious options but this ipolex variant running Intel X520 seems to be getting good reviews. (https://www.amazon.sg/gp/product/B01IR7SUEK?smid=ARPIJN329XQ0D&psc=1)
- Cost is very reasonable at around $75.
- Do let me know if there are better options stability and performance/heat-wise.

Cables
- RJ45 cables will be re-used. They are all CAT6 and above.
- For SFP+, I intend to get from UniFi's DACs since the switches will be from them. (https://sg.store.ui.com/sg/en/categ...ch-cables/products/10gbps-direct-attach-cable)



Do let me know if I am missing anything or can do better. (I have been combing the threads in this forum. Grateful for the experience shared here.)

One typical question from the forum -- what if I have two or more 10Gbe capable wired devices?
Answer -- you need a 10G capable switch.

https://forums.hardwarezone.com.sg/...-deco-wifi-6e-7-mesh-solution.6953682/page-29

Yes.

HB810, only two 10G ports can be used. The SFP+ port is basically useless in this case, as it is a combo port. If you use the 10G RJ45 WAN Port, the SFP+ port become not functioning.

All the ISP issued XGS-PON ONTs and XGS-PON ONRs will have only one 10G capable port.

All the ISP bundled 10G capable wireless routers will have the same problem. They only have two 10G ports, one for the WAN and then the other for LAN.

If you need more 10G devices, you have to buy a 10G capable switch.

This is basically true for all consumer routers, including the expensive ones like Asus ROG GT-BE98.

1G only. All the ISP issued XGS-PON ONR has one 10G port and a few 1G ports. None of them have 2.5G ports.

All the ISP issued XGS-PON ONT has one active 10G port only and the 1G ports are not functional.

Reference from Singtel:
https://www.singtel.com/content/dam/singtel/eshop/Fibre/agreements/10Gbps-FAQ-WiFi7.pdf

More about 10G capable router and switch: one popular lower cost pure 10G switch is Srinivision SR-ST3408F (quad 10G RJ45 ports and quad 10G SFP+ ports), less than S$200.

Thanks much for the advice and tips! After more digging, I've decided to go with ubiquiti - 1x UCG Fibre, 3x Pro XG 8 POE and 2x U7 XGS. The SFP+ PCIe cards and TB4 adapters have started coming in and most of them work well (1 PCIe DOA).

I also decided to run two connections - 1x M1 10gbps and 1x MR 1gbps (current - will move it to 3gbps when my contract is up). This is because uptime is important with the amount of stuff I am hosting.

Take a look at Mikrotik offers, something like CCR2004-1G-12S+2XS or CCR2116-12G-4S+ or even ccr2216-1g-12xs-2xq
For switch, crs309-1G-8S+IN or the 100G crs504-4xq-in switch ( yes, dont be shy when getting 100G swiitch, nice thing about 100G is you can easily break it out to 25x4, I heard people could break it into smaller 10Gs when use QSFP28 breakout + MPO fanout , but i diidnt test it myself)

If you dun need local warranty, can just order straight from oversea , it save you some (alot) cost.

Its quite sometime since the last time I used Unifi, thing I dont like is the restriction it gives ( can not change interface from lan to wan and vice versa) , while Mik give you total control. It wont stop you even if you put stupid config.
1 more thing to note is : ubiquiti is like Apple, it work well when use together within iits ecosystem, but in mixed brand network , its abiit troublesome to get things work together the last time I did.

This is because uptime is important with the amount of stuff I am hosting.

btw both brands wont solve ur uptime im afraid. If the reason you get dual WAN because uptime is important, then you need sd-wan capable router , something liike peplink SD-Wan router or Fortigate 90G or this
Of course sw-wan is way too overkill for homeuse , so we can opt out that.
