Archer C9 TP-Link Router loses connectivity (red internet signal) when uploading.

[ftlepore]

Not sure if I simply have a setting misconfigured or what. I recently set up a new Archer C9 router to my Comcast modem and while my speeds are normally great, whenever I attempt to upload a file to something like YouTube, the Internet becomes completely unresponsive and the blue Internet icon on the router goes from blue to orange ("The Internet port is connected, but the Internet is inaccessible" according to the manual). Additionally, when I go into the router settings there is a caution triangle next to the Internet status. After a few minutes the light goes back to blue and things seem normal again.

Not sure why this is happening or what additional information may be needed to diagnose this but this didn't seem to happen with my previous router. My connection is also the only hardwired one on the network and no one else is using the internet at the time as I am usually the only one home when this happens.

Does anyone have any idea what's going on?

What Comcast modem do you have?

The most straightforward thing to do is call Comcast and get some assurance (as best you can) that the problem is not on their side of things.

Then the next step would be to look into the modem and router logs to see what events they are logging.

Could take a few "go-rounds" if you are dealing with an intermittent problem - something like a loose connection....

Probably would not hurt to take a look at your incoming cables and connectors. Look for cracked insulation, corrosion, kinks, etc..

I'm having similar issues with my FIOS modem. Problem is intermittent Most times everything is fine, but occasionally everything grinds to a halt. Worked with Verizon customer service and they say nothing is wrong with the modem or on their end.

Do you also have a router connected to the modem?

If connecting directly to the modem resolves the problem then the problem is probably internal to your router and network.

The another consideration is the problem being intermittent. Yes, you can call Verizon and they can say there is nothing wrong because, in all fairness, the problem just is not happening at that moment.

Do another round of internal troubleshooting: swap out any ethernet cables with known working cables. Inspect inside any network wall jacks for punchdowns that may be loose, corroded, or touching another wire. May sure all connections are secure and tight.

And try Verizon again when you see the problem occuring. Maybe they will be able to detect and identify the problem.

As before look at the router and modem (if possible) logs. Any errors, warnings, or reported events at the time of problem may help identify the cause.

Have Archer C9 too, Don´t use or setup 5Ghz 80 mhz/auto, use 20mhz or 40 mhz. Here stop the random reboot and crash.
Have Archer C2600, this work perfect, Archer c9 i considered a bad investment, too many bugs and issues.
