<td>I set up my WRT310N v2 with DD-WRT to be a Wireless Repeater using the below guide except I created a virtual wireless interface which for some reason wasn’t in that guide so I could connect wireless devices (the point of it all).<p><a href=”https://web.archive.org/web/20170816093835/https://www.dd-wrt.com/wiki/index.php/Repeater_Bridge” target=”_blank” rel=”nofollow”>https://www.dd-wrt.com/wiki/index.p…</a></p><p>It worked for a couple months and then devices were dropping left and right.

My guess is that maybe there were too many routers in your area with overlapping channels?
It could also be that the ATT wireless router/modem was failing too though because of internet issues.
The manual stated that WPA2 Mixed will most likely kill the communication.
13. Once you have it working, go to the wireless security tab, and set the same type of security AND key for both the primary and the repeater ssids and hit apply. Avoid WPA2 Personal MIXED, as it will likely kill communication between the routers (see Security section below for more on this). WPA2 Personal is fine.
Security
Dd-wrt will often not work unless BOTH the primary router and the secondary router use wpa2-aes security ONLY. Wep will also often work, but it is not secure.
Go to the wireless tab.
Choose Repeater Bridge under wireless mode.
Match your SSID and channel settings exactly to the main router you will be connecting to.
Make sure bridged is selected.
Click Save.
Click Connectivity.
Click Internet Settings.
Click Edit.
Select Wireless Repeater.
Enter the main router or access point’s Network name (SSID), Network band and Security mode.
Click to save settings. Click Yes to continue.
