Hi, does anyone have issues connecting with a mini 4? I bought one on Saturday. The wireless is weak and does not connect to known good WiFi. Flaky at best. I had a first generation mini and the wireless was poor also. Wondering if this is a thing with the mini? I am in the return period so this issue can be easily resolved if wireless is a known issue. All the other Apple products connect easily. The router is AE so compatibility should not be an issue. Thanks!
