Fiber optic weird issue.

[RexTheRipper]

Hello people,

Riddle me this. My internet is fiber optic with 1gb/s speed. Now I have this weird issue every few days that it gets stuck on 90 mbp/s. I have to disconnect my lan cable, power down fiber optic router and in the meanwhile restart my pc. When my router shows it's reconnected then plug in the land cable. Yes this issue solving wouldn't ever get into the minds of the people at Telekom (germany). The router is Speedport Pro

Why the hell is this happening tho and how can i do a longer time fix on this? Kinda annoying when you are gaming and other use the net and it slows down and u lag in game.

Thanks for the answers before hand.

Does the Ethernet cable run around anything high power? Like something maybe with a motor or something in it? Ethernet is susceptible to EMI. The other thing is maybe the cable is slightly defective, like to a point where the router and device can negotiate a link at 1 Gbps but something changes and it ends up having to negotiate at a lower speed. Only 4 wires are needed for 100 Mbps, while all 8 are needed for faster speeds. 

 

So Id check to make sure the cable is clear of anything high voltage electrical. If it is, then just replace the cable and see what happens. If it fails again, its a possibility its an issue with the Fiber router, and you may have to demand a new one from the ISP.

No, it is not. Also the router just goes 90 mbps on all devices not only my PC. Also I can regain speed by just unplugging my fiber "router" after I unplug my net cable and plug it back. It's weird as heck honestly. Maybe I should get a network card, see if the onboard lan messes with my router?

If it messes up on all devices then it’s the router not the pc. Ask for a new router.
