single inside home bounces from no signal to roam, if you try and move while talking the signal fades. I have an aircard for internet and use an external antenna, normally it's around 80%, till quitting time on fridays, then it bounces between 0% and 60% and as soon as you launch an application that trys to use the internet it drops to 0 again... very frustrating. Tech support gives same song and dance, upgrade your equipment, etc., I wish now I'd not renewed my contract.
