I have a droid razr and thinking about upgrading to the razr m but I have had some wi-fi issues with my razr wondering if anyone has had any wi-fi problems with there razr m
This is your second post re: the WiFi issues you're having. Not all devices see WiFi the same due to differences in chipsets and the firmware in the phones. I have a link below that you may want to check to see if anything makes your Droid work better regardless of the iPhone's performance. If the problem really is the router or a setting in the router going from one Moto to another may leave you in the same ditch.
Try viewing on a friend's WiFi or a public hotspot to try ruling out you phone as the problem.
It's also possible you have 1 or more apps doing things in the background that would interfere. That could be a long list. But you could start with active widgets and mail checking.
