I have a problem with my TL-WN881ND Wireless PCI Express Adapter
The adapter has been installed/connected to the computer and the drivers have been installed, but when I tried to connect to my wifi network it says "unable to connect to this network" and on the times that it would connect to the network it would only have internet access for the use of about 40mb and then it says "no internet access" and this doesn't make sense because the wifi is uncapped and works perfectly on my other devices.
I have gone on to the TP-Link website and searched my adapter and I have watched the troubleshooting/common problems video and I uninstalled all the drivers and reinstalled them while following along step by step with the "TP-Link Wireless Adapter Setup and Installation Video" as the troubleshooting/common problems video said I should, but the problem is still not resolved.
My router is the TP-Link TL-WR840N, I have tried changing the channel and channel width and that did not fix it.
I just got a new PC and would really like to be able to use the internet on it, so any help to solve this problem is appreciated
