Hello,

So I'm experiencing some weird issues with my TP-Link router . It's a Archer C6 (only 1 year old) and the speed has been reduced to 100mpbs.

Before I state the things I tried keep in mind that my current exact setup worked at 1 GBPS before. I was away for a couple of months and when I came back it just bottlenecks at 100 MBPS.

Things I tried :

- Tried different cable

- Tried different computer

- Tried manually setting the Speed & Duplex to 1000mbps but it didn't even detect the connection

- Tried manually setting Duplex in router settings to 1000MBPS full duplex, it doesn't work

The only way my PC automatically detects 1GBPS when I plug it directly to the modem .

I know it's something up with the TP-Link router, and If I recall correctly it might have been after the Firmware upgrade but not sure.

Does anyone else have this issue? 

Is the firmware update at fault ? if so can it be downgraded to an earlier version?

Edit:

The 5GHz connection works is at 1 GBPS , the lan ports are the only ones affected .  This is definitely a trend with TP-link routers from some google searches.

Thanks
