iPhone 5 with iOS 6 not working with Xfinity Combo Gateway

I have an iPhone 5 with iOS 6 and it connects to a Xfinity Arris TG862G/CT Combo Gateway. I can connect to the network fine and even get internet connectivity, with Safari for example. However, some of my apps do not function properly. For example, my phone will not back up to iCloud, and my mobile banking app will not connect to my account. If I switch to a different router, they work fine. I have looked at the settings on my router and nothing stands out to me, I have also tried resetting the router several ways, by accessing it through Safari and sending it a command to reset to factory defaults, by pressing the reset button on the back, and by removing the battery and unplugging it from the wall. Still the same issue, I have also completely disabled the firewall in hopes that was the issue, still same issue. Does anyone have any other ideas?

I have very similiar issue. I got Iphone 5 and it and my Ipad stopped ICloud backups on same day (Oct. 15th). It starts to backup and then says "cannot complete". I went into Apple store thinking it was issue with my Icloud account. They connected it and it worked fine. They recommended powering off/on the router which I did, but it didn't work.

Has anybody else been facing this issue and found a solution. Please help, I have tried everything!!!!

I have the same issue as well I wonder if it's all xfinity routers so I'm going contact Comcast and replace the router and contact apple expresslane support if replacing the router doesn't solve the issue.

It is more than likely the router. I have seen this issue with friends I have with that particular router. I have Comcast/Xfinity, however I have a stand-alone modem that is one of the older ones that does not have a router/wifi built in. I have my modem connected to a different router and have no issues with Comcast/Xfinity Internet.

Have you seen this:

I'm not sure this is the problem, but getting a replacement from Comcast is the way to go. Their modems are notoriously awful, and it's never been a problem to get a replacement. In fact, when the service was upgraded in my area in the last few years, I went through three modems before I got one that worked reliably.
