Aztech DSL7002GRV-(s)

[mOomOo]

wait till i get my hands on the new router la... still waiting for info on collection. supports... AC?

More info pls.. rumours also can..

 

[CarbonoAtom]

AC router?????

Which model/company?

Aztech????


But I would'nt prefer an ac router now leh, not all devices compatible, wait for a few more years, then there would be more computers with the ac adapter inbuilt in them, whereas there are ac adapters in phones, but their speed is not as exceptional as ac adapters which are on computers. GO wireless-n! Lol....
But I agree ac would be waaay faster than n, if it might be aztech's one, their products are improving in quality....

I am also planning to do this. On 500mbps singtel with grv7000, the wifi signal is abysmal. Can any pros give a rough guide as to how to do it?

I am interested to find out how as well... I'm not entirely sure but currently I have MIO at home, and my N66U is on the preset MIO profile, WAN is on automatic IP.

Is it the same for normal non-MIO fiber?

Anyone knows if the 7002 supports 802.11AC or up to N only?

I can't seem to find anything on the internet about this router. Aztech official website only has specs for the 7000 model.

No wireless AC

No wireless AC

Thanks. And is it simultaneous dual-band or must select one every time?

I am also interested to try out the wireless bridge method to 3 bedrooms, but with the DSL7002GRV(S) in full mode, not bridge mode. That means it continues to do the DHCP and the main routing part. Reason is I have mioTV and I want trouble free connection to SingTel. Furthermore, any of the 4 LAN port on the DSL7002GRV(S) can be used for mioTV (potential for a 2nd set top box), unlike the ASUS which can only use LAN port 4, and only 1, for mio TV.

The problem is distance from the DSL7002GRV(S) to the desks in the 3 bedrooms are at least 12.5 metres and no line of sight. The routers in there will be connected by LAN cable to PCs and Xbox360. Bridged this way will avoid the 50% to 60% speed drop penalty of repeaters. I figure the distance can be a problem but never know if never try. Perhaps I find some free time to experiment.

Just for a test, a 2011 Mac mini and the DSL7002GRV(S) 1.5 metre apart on the TV console. Connected on the 5Ghz band channel 157 with channel bonding. Fibre plan is SingTel 200Mbps.

Wireless, not wired.

Did you set any custom settings on 7002 to achieve 200mbps using wifi?

No special settings. Using WPA2-Personal and AES. But note it is 1.5 metre on the same TV console.

 

[BestPilot]

What do u mean by same tv console?

 

[upgrade]

The Mac mini and the router are 1.5 metre apart on the TV console. Mac mini on the left, router on the right.

I did another speedtest and get a screenshot of the WiFi spec and
a search for more details.

From the IFixIt tear down of the mid-2011 Mac mini:
Mac Mini Mid 2011 Teardown - iFixit

From Step 10:
Broadcom BCM4331
Picture shows 2 antenna cables (but board has 3 connectors)

From Step 12:
2 antennas at back black plastic piece

Speedtest this morning:

Screenshots:
Note all the entire 5Ghz channels are supported by the Mac mini.
Note only 2 channels 140 and 165 not in DSL7002GRV(S).
Default of 22 channels supported. You don't even get this in those
expensive >$300 routers, not even those AC. Unless you use
3rd-party firmware for those expensive routers.

Actually all routers can support it but it's up to the manufacturer whether to offer it as an option (in the firmware) or not.

Off-hand, I'm 100% sure Padavan (just set WiFi to debug mode) and Tomato can do that too.

However, do note that those channels that are not meant to be operated in Singapore will have a lot of compatibility issues with most client devices (smartphone, tablet, laptops, etc.).

Previously, I refered to this wiki and thought that channels 100 to 140 were not allowed for 5Ghz WiFi use.

List of WLAN channels - Wikipedia, the free encyclopedia

I was wondering how could SingTel issue a router that use "unauthorised" 5Ghz channels (read frequencies). They would run foul of iDA regulations and risk what may come. I was wrong. That wiki was not up to date I don't know since when. And SingTel did nothing wrong.

From the authoritative iDA document:

http://www.ida.gov.sg/~/media/Files/PCDG/Licensees/SpectrumMgmt/FreqAllocAssign/RSMP.pdf

From page 10:

QUOTE

(b) Radio Local Area Networks (RLANs)/5GHz

Radio Local Area Networks (RLANs) include networks using IEEE802.11 and HiperLAN standards.

IDA has opened up 5150-5350 MHz, 5470-5725 MHz and 5725-5850 MHz for wireless access systems

UNQUOTE

So, 5150-5350 and 5470-5850 MHz. Refer back to the wiki above and these correspond to: channels from 34 all the way to 165.

Hi elpibe10,

Thanks very much for your help at the other thread. Much appreciated.

I will want to try again later.

Regarding Padawan, if I remember correctly the debug mode is only for the 2.4Ghz band. This will go from 1 to 14. Whereas for the 5Ghz band, have to choose country. I chose Europe because that gives me the some of the lower and the upper channels. The "middle" channels not available. I think most of the country choice only have lower.

It is true some devices cannot use certain channels. What I have:
1) HTC Desire HD 2.4Ghz only - 1 to 11, no 12 and 13
2) Motorola Xoom - 36 to 48 and 149 to 161
3) HP Touchpad - 36 up to 153
4) iPad 2 and iPhone 5s - 36 up to 161

Just VPN home to check. Yes, the 5GHz band has debug mode too.

If the manufacturers follow regulatory guidelines, their device should only function within the country's frequency range. That's why it's quite pointless to set your router / access point to those unsupported channels (eg. Channel 12 or higher on 2.4GHz).

I did try setting to Channel 13 (2.4GHz) some time back and my MacBook Air couldn't connect to it.

However, if you're only doing wireless bridging (i.e. wireless connection between Aztech router and Asus RT-N56U set as bridge), then I think it should be fine if both devices support those 'odd' channels

I was able to access channel 13 on all my devices(channel 13 is 2.472Ghz) Maybe it depends on what gadget you use and if it supports that frequency then it's good for it. For me I feel that the use of 2.4ghz is greater as it in the end has a long coverage area whereas 5ghz covers only a small area but has a greater bandwidth comapactibility...

Btw, when I do this , settings, my wifi on 2.4ghz dosen't work does anyone know why????

 

[upgrade]

The iDA Authorised Frequency Bands/Frequencies for Wireless LAN is 2.4000-2.4835 MHz. This translate to 2.4Ghz channel 1 to 13.

Page 16 of the iDA document:
http://www.ida.gov.sg/~/media/Files/PCDG/Licensees/SpectrumMgmt/FreqAllocAssign/RSMP.pdf

Based on the iDA document, the authorised channels for Singapore are:
2.4Ghz:- 1 to 13 (complete, no gap)
5Ghz:- 34 to 165 (complete, no gap)

This is the widest range possible anywhere in the world, reflecting iDA's good foresight.

I think routers and devices sold in Singapore should "ideally" work in these full authorised ranges. I stress "ideally" but we are not in a perfect ideal world.

1) Ideally for the routers, offer a wider spread to the layman users to avoid the congestion in the 5Ghz band that the 2.4Ghz is now suffering. I was surprised that the local RT-N56U only have 4 default channels in the 5Ghz band. Layman will be stuck.

2) Ideally for devices, to avoid the situation where they cannot connect to the router, especially when the router is set to auto-channel. I think we see a lot of this layman problem in the HWZ forum.

If your devices/clients cannot connect at those rates, then they will not connect. Better to set it to auto, unless you very sure they are capable of those rates.
