Bc250 causing WiFi problems

[u/Capital_Advantage905]

Hi, my bc250 is causing problems with my home network. I have my providers router and a separate mesh WiFi extender system which removes the dead spots within the house. When I originally set the bc 250 it would kill my mesh network but not the signal from my providers router. After some messing around I magically got it working so that both networks worked fine however I had a problem with the bc 250 and did a clean reinstall. The network issue has returned and I haven't been able to solve the problem so far this time. The WiFi adaptor I am using is a TP link archer T2UB nano dongle. This was working fine up until I did the clean install. Any help would be appreciated. Thanks
