[SOLVED] Speed tests not showing full internet speed

[Denkata121]

I recently changed my ISP and upgraded to a 500mb/s speed. I know I probably wont get the full speed but on my phone (a52 5g) with wifi i get about 250-300mb/s but on my pc (hooked up with a cable) I can barely get 90mb/s. Im using the mobo LAN but I dont think its that since its a gigabit LAN card (b450m pro4-f). If i didnt give enough info please tell me and ill provide it.

Is the motherboard plugged directly into the ISP router or is there some in-wall cabling?
250-300 on a phone with WIFI is pretty typical.
What router do you have?

No other cables. Direct cable to the router (20m if it matters ). Router is Nokia G-2425G-A. Its the router they gave me and also no i cannot play with the settings of the router.

Is that 20m cable a "flat" cable?
Is the speed and duplex of the ethernet port set to Auto ?

Nope standard round FTP cable. Also yeah its set to auto.

ISP ONT choice seems fine. Are you definitely sure that your home cabling is fine? Take your computer near ONT (laptop with 1 GBe Ethernet port will be easier) connect with Cat5e cable and check internet speed.

tried with a different cable and it worked. btw the 20m cable is self made but i just double checked it and its fine. Could it be the cable?

Any cable can fail at any time. All it takes is one of the 8 wires to not make connection and you get 100Mbit rather than 1Gbit. Replace with a commercial cable, IMO.

Yes. Replace it with a COMMERCIALLY MADE cable.

I can crimp 1 GBe capable cable in 2 minutes from Cat5e cable piece and RJ45 connectors lying in my shelf behind me which will work not worse than premade cable sold in shop. Speed issues in OP case most likely caused by missing wires in connector (only 4 wires instead of 8), teared wires or wrong connectors. In any case - OP, replace that cable you have now.

1 its a 4 pair wire 2 wrong connectors? 3 My cable has to be self made since it goes through a wall.

I re-crimped the cable on both ends and now its full speed.
