Been doing some research and am having a hard time finding what I am looking for. Back in the day, I used a device, I believe it was a Cradlepoint, that one could connect various USB wireless cards into one device and either combine the signals, use the strongest, etc. It would then broadcast a Wifi signal that devices could connect to using all the networks at once or the strongest network. Does such a device still exist? Are they Cradlepoints? Recommendations are particular devices?
