C6300 dropping Wifi connection

I haven't found any solutions on the forum and this seems to have been a problem for years now. I have the latest firmware from suddenlink, and everything seems to be in check.

My C6300 will drop its wifi signal periodically without showing so on the light display. SSID can't be found or anything, and I can only get wifi for 5 mins tops after a reset.

Re: C6300 dropping Wifi connection

You've posted this in the wrong place (ReadyNAS) - I've moved it for you.

 

Do you have any ethernet devices connected?  If so, do they lose connectivity when the WiFi drops?

 

Also, are you losing the SSID on both bands (2.4 ghz and 5 ghz), or only one?

Re: C6300 dropping Wifi connection

I am only using wifi connections with my desktop and my phone. The desktop is only 2.4ghz capable but my i-Phone loses 5g as well, so yes, I am losing both bands.

The disconnects seem to be infrequent - at times the connection will only last a few seconds before a restart, but as of this post I can last up to 20-30 minutes. Another factor that seems to trigger a failure to broadcast is connecting to certain high traffic sites/games.

 

I can send a list of system specifications but for now here are the ip v4 ping test, ip v6 ping test and event log from the router page.

Re: C6300 dropping Wifi connection

You do seem to have alot of T3 timeouts which is typically a issue with the ISP. you may want a tech to come out and check the cable lines.
