TP-LINK Archer C7 Internet Issues?

[Carnagerover]

Hi all,

For some reason lately my C7 has become unstable when it comes to the internet, I use PPPOE and basically what happens is all devices lose the internet, however both the modem and the C7 are fine. I can disconnect and reconnect the internet and I have a WAN address, DNS and the lot but my internet still doesn't work. So I have to reboot the router in order to get it to start working again.

Rebooting any other device like the modem or anything else has no effect, every other function of the router works fine when this happens apart from the internet.

Anyone have any ideas what its all about

Since you get a WAN address, the PPPoE seems to be working OK. When your "internet doesn't work" happens, is this true for a PC that is wired to the router? Eliminate WiFi for the moment.
Could be many things... we'll need to do some tests with ping, and check DNSes,...

Thanks for the reply Stevech I managed to cure it by replacing the modem, not sure what was going on there.

It could be anything. When networking gear goes haywire, any kind of crap can happen. I have a pair of Netgear 3500L (V1), one as a router, one as an AP. Well the one that is currently an AP, I had been running as a router.

Then one day I lost my internet connection on all devices and I couldn't login to the admin page, but the WLAN functionality and switch functionality was working perfectly. Rebooted it, all was well. then 24hrs later, the same thing. Reboot (I had JUST been making changes the first time it happened, so I figured it was related to that) and restore the settings, 12hrs later, same deal.

That night I swapped the 3500L to run the old AP as the router and vice versa. The "broken" one works as an AP/switch just fine, with only rare hiccups where it'll refuse connections on a device that has roamed on to my router on the otherside of the house. That happens about once a week and its 50/50 with rebooting the router or rebooting the device that allows it back on the "broken" AP. That is the one I am looking at replacing with a C7 Archer soon.

A couple of weeks ago I had a power outage that fried my Verizon ONT box, but nothing else seemed effected. Then I noticed that my server started losing internet connection and a media streamer couldn't connect to the server (but the other one still could), I thought fried streamer and router issues. I got an Apple TV, it could see iTunes on the server, but couldn't connect, then my desktop started having internet connection issues, then SMB multichannel stopped working and I had been noticing PINGs didn't work between certain machines on the network from certain LAN drop locations.

It finally clicked when I got SMB multichannel working by plugging my server an desktop in to a spare 8 port GbE dumb swith I had laying around that is must be the switch. Factory reset it and EVERYTHING was working fine again. Seemed to be a wierd issue of not switching some/most/all IPv4 traffice (IPv6 seemed uneffected and actually when I disabled IPv6, my server pretty much got knocked off the network completely when troubleshooting). My only guess is, as an L2 switch, there was some kind of freakish "storm control" or DoS port protection that went haywire on it and didn't reset when I had powered the switch back on after 36hrs of the power outage, but the factory refresh fixed it.
