Hello, I just bought a new router form my ISP and is a combo router/modem (Comtrend AR-5381u) and my desktop can connect via wi-fi just fine, serf the internet and whatnot at the speeds I pay for, but on whiles its on Ethernet (which i vastly prefer) the connection is awfully slow and i cannot connect to anything on the internet (usually works slowly for about a minute) I get DNS_Probe_not_found and time out and have huge latency issues. I use a static IP so i thought that would be the problem so i went back to dynamic ip and the problem still persists (I also set my DNS server to 8.8.8.8 and 8.8.4.4), I know that my LAN card is not the issue because my Ethernet worked fine literally right before installing this new router. I would appreciate help on this! thank you!

run the following in command prompt:

ipconfig /all

on both WiFi and wired and post the results.

i am looking for the IP config results, all of it.

you can use ipconfig /all > c:\ipconfig.txt

to send the results to a text file for easy copy pasting. there is no personally identifiable info in any of this, just network settings, most likely wrong, every computer has those.

according to what you have posted above your network card is not connected. Please confirm the Ethernet cable is plugged in and there is a green light on both the network card port and the the router port.

Hahahahahaha if it were that simple then I would not be posting here! Yes it is plugged in because I can still get onto the internet (sometimes and very slowly) while on Ethernet and my wi-fi card disabled.

Opps I did this while on my wi-fi card (not Ethernet), maybe that was the problem?

disable WiFi
open 2 separate command prompt windows
run the following ping tests, for a about 5 minutes, press ctrl + c to interrupt them and look for statistics at the end, post results

ping 8.8.8.8 -t

ping 192.168.5.1 -t

Weird, there was a TON of results in CMD but it only saved a few of them, but I did indeed run it for 5 minutes.

something went wrong with the test, looks like you tried multiple times and the results you posted are inconclusive because very few packets were sent 8.8.8.8 - 10 packets sent, 192.168.5.1 - 29 packets sent and 216.58.218.206 only 2. I am interested in the part at the very end, "Ping Statistics" and below. but for the results to be meaningful we need to send about 1000 packets.

Ah I see, but in the end I managed to fix it by uninstalling and reinstalling the drivers. I don't know what went wrong but if it works now that is all I am interested in! Thanks so much for your help man! I know that doing all of this is a lot of work because some of my buddies wouldn't help me without cash in their hand! Thank you so much!

you are welcome, glad you figured it out, those killer NICs do have weird driver issues sometimes.
