Hello and Good day!
Yesterday, ISP internet suddenly slowed down. It has been restored, but my desktop internet is still slow when connecting to 5G wifi using TP link AC1300 lan card. I can't connect to 2.4G networks totally through lan card. Using a 2.4G wifi TP Link TL WN722N usb dongle, internet was normal.
Summary of wifi connections I tried:
-
Desktop lan card 5G - 0 to very slow
-
Desktop lan card 2.4G - Can't connect
-
Desktop usb wifi dongle 2.4G - normal speed
-
Laptop 2.4G - normal speed
-
Mobile phone wifi 5G - normal speed
(Note: TP link connection to router is only 6 MBps, when it shoud be ~800 since the signal strength is strong)
Everything else other than connections through the tp link AC1300 seemed to work fine. It was also fine before internet outage. Also tried uninstalling and reinstalling driver, but did not work.
Is this a software issue caused by internet outage? Or did the outage damage the lan card? A coincidence?
Thank you very much!
