Openwrt Router Firmware

[BBCWatcher]

BTW, I'm also trying to setup a NAS with another EA8100 on OpenWRT but windows keep giving error but can see the drive.

Have you tried NFS?

Have you tried NFS?

No, Samba and Ksmbd.

 

[windwaver]

I see.

In that case, Adblock-fast should be okay to go, you may need to be careful about the DNS block list used as big can cause issues with both RAM and Flash storage. Use smaller list first to see how it goes.

As for simple NAS function, do not put too much hope on it.

@xiaofan I was using the default OS for sharing no issue but wanted to try OpenWrt and so far can't get it to work.

 

[BBCWatcher]

No, Samba and Ksmbd.

Give NFS a try. Windows ships with an NFS client that you just have to switch on. This PowerShell command should do it:

Enable-WindowsOptionalFeature -FeatureName "ClientForNFS-Infrastructure" -All -Online

Hi @BBCWatcher and @xiaofan , thank you for all the help.

Ironically I managed to make the Samba share work by using DD-WRT on an older router.

The drawback is unable to copy large data of files all at once because of the weak CPU and doesn't support double byte filenames due to lightweight Samba implementation.

Yeah, OK, so try NFS. It’s typically lighter weight and better optimized for the Linux operating systems you’re using. Windows has included built-in NFS client support for eons, so it’s not some alien creature. YMMV, which is rather the point.

Take note NFS feature is not available for Windows 11 Home Edition.

Wired client -- Acer Swift Go 14 Windows 11 26H2, with XikeStor Type C hub buit-in 2.5Gbe adapter connected to TR3000 2.5Gbe port. You can see it almost uses the full bandwidth from the wireless uplink.

I took a leap of faith and added a OpenWrt VM in my proxmox server to find a way to isolate my TCL tv from rest of network after the LG tv spying fiasco. Managed to do it while still keeping the current network setup (asus router) without pissing my spouse. i know it is like using small part of what openwrt offers but i am quite happy that it had worked out with the help of claude. Looking forward to move rest of vlans to openwrt and learn from all the shifu here

• Moved tv out of main network to separate vlan with dhcp server in openwrt
• Need to have a guest network pro with same vlan tag in order to have wifi access (if cannot ethernet) but the vlan ip should be different so that asus router redirects to openwrt to let it do its thing
• Enable avahi mdns so that spouse still can cast and airplay to tv
• Rest of network other than iphones (airplay) and jellyfin is blocked by openwrt firewall

Hi @xiaofan , any idea what I can do with another old EA8100 on OpenWRT?

Hi @xiaofan , any idea what I can do with another old EA8100 on OpenWRT?

What is your ISP plan and main router used?

An old Linksys EA8100 running OpenWRT can be used as following.

1) As the cheapest main router, say in the DB box (disable Wi-Fi if necessary), not that good now that most users will have 5Gbps or 10 Gbps plan

2) As an AP to extend wireless network coverage, if you have LAN ports in the rooms

3) As a range extender or media bridge to extend wireless network coverage, if you do not have LAN ports in the rooms

4) As a simple network file share or media streaming server by adding a USB Drive.

5) As a filtering DNS server (similar to Pi-hole) to block ads and unwanted websites

6) As a dumb switch

7) As a managed switch and use VLAN for network segmentation

...

2) As an AP to extend wireless network coverage, if you have LAN ports in the rooms

It could also be used as a dedicated, segregated access point for a guest or "IoT" network — even if you're not trying to extend or improve Wi-Fi coverage. For those purposes you'll probably want to configure a 20 MHz wide channel on 5 GHz. (You'd always do that anyway on 2.4 GHz.) Channel 165 is often a good candidate.

Adblock-Fast? TIA.

Main router (eg: 192.168.50.1) -- EA8100 V1 in AP mode with WiFi disabled, static IP address (eg: 192.168.50.240).

EA8100 V1 running OpenWRT and Adblock-fast and maybe also DNS over HTTPS.

Set the main router LAN clients to use 192.168.50.240 as the DNS server.

Set the main router LAN clients to use 192.168.50.240 as the DNS server.

That make sense, as long as the Adblock DNS is sitting anywhere in the same network.

That'll free up workload and memory for the main router.

Let me try.
