Archer A7 WAN Port Negotiating 100mbps
I have an Archer A7 router that until a few weeks ago was getting ~200mbps speeds, but now seems to be capped at 100mbps.
I have connected my laptop directly to the cat7 cable that plugs into the router's WAN port, and when I connect directly I get my full speed, so I know my cables leading into the router are not damaged or low-grade.
When I look at my router's UI and check the negotiating speed. It says that the Internet port is neogtiating at 100mbps.
I have already tried going into system parameters and setting auto negotiate to 1000mbps, but this did not help.
I have performed a factory reset on the router and this did not help.
What else can I do?
