XR500 WiFi disconnect issues

Recommended Posts

It's the Arris BGW210-700. I've already clicked on every search result that seemed relevant but no luck. If you still want to try though, I'd appreciate it

Sorry, I didn't get a notification about your reply. I got IP passthrough to send the public IP to the router but still didn't help. The cascaded router thing is only if you're an AT&T customer with a static allotment of IPs from them, not for this purpose.

OMG! It is the modem. After reflashing and resetting my router many times, I found that if the router starts and lets devices connect before I plug it into the modem, the internet works for all the devices that connected before I made the connection. If I turn the router on while it's already connected to the modem, that's when I get random devices failing to connect. How can this be? It's a modem and the devices shouldn't care what's beyond the router. I found this problem happening in both versions .40 and .56. I'll contact AT&T and see if they can give me any advice or replace the modem.

Does it still work in this scenario? We'll continue to investigate but I can't think of anything else to possibly suggest at the moment.

Yes but as soon as I connect the router to the modem, devices start having problems connecting if they weren't connected before I plugged the router into the modem. So devices connecting to the router while it's not connected to the modem can get a valid IP from the DHCP but it stops giving consistently good IPs after I plug the router into the modem.

Disabling DHCP and setting Static IPs isn't viable/doesn't work either correct? Do you have a spare router by any chance that you could use in AP mode behind the XR500 and connect devices to those and see if that stops the issues? That way you could still use the XR500 features and have no disconnects.

A big reason why I wanted to use the XR500 was because of the better wireless capabilities. Unfortunately it doesn't seem like it is going to work and I've decided to return the XR500. Thanks for trying to help figure out what was going wrong. I appreciate it.

My final setup for anyone watching this is to use the AT&T gateway as the main router and DHCP server but with the WiFi turned off. I have my R7000 plugged into it in AP mode and am using that as my wireless signal.

Sorry to hear that, totally understand you don't want to miss the return window. Hopefully the cause of this will be discovered, I hope you continue to follow what we're up to and maybe consider us again in the future.
