I installed Archer T4E adapters in two desktop PCs running Win10, different motherboards. Neither T4E will connect to an Archer MR200 router but connect out the box without configuring immediately with a Netgear router running dd-wrt. I have tried different versions of drivers that I found on the TP-Link website and that came on CD in the box with the T4Es. All connections are 2.4G and other devices (cellphones, TV, laptops...) connect to the MR200 2.4G no problem. Wifi connects to the MR200 from the T4E's (after entering the key) but there is no internet connection and I cannot ping the MR200. I have tried different security settings to no avail. WPA2 Personal/AES is what the router is set to and other devices connect no problem using this setting. What other settings should I be looking at on the adapters and/or the router?
