I have just changed my mobile phone supplier and number and have the same smart-phone but a new sim card. My previous phone worked fine with connections to my Surface. I now have a connection, but it is limited and has no internet ability, despite the connection. I have tried playing with every setting I can find to no avail. My phone link is AndroidAP with security options of WPA PSK; WPA2 PSK; or Open. My Surface security options are Open; WEP; WPA2- Personal; WPA Personal; WPA2- Enterprise; WPA-Enterprise; 802.1x No setting seems to match between phone & Surface. Is this the problem? Any advice please to get my Internet operating? Thanks.
