[SOLVED] Do I really have get extender re-flashed to solve this problem?

[Telorast]

Changing from AT&T internet to Xfinity. My wifi extender is a 2 yr old Netgear 3700. I connected it to Xfinity & a popup said it was making extender bands, but it there aren't any new bands for Xfinity. I only see the defunct AT&T bands... ATT_2GEXT & ATT_5GEXT. I could not find a way to remove or delete the AT&T extensions. Finally called customer support and the tech guy said that I won't be able to use my current extender unless he re-flashes the firmware & makes other adjustments... $50, please. I said I'd be better off putting the $$ into a new extender. He said I will have the same problem with any new extender I get. Really... people change internet providers all the time. I don't see how this problem can carry over if I get a newer extender. Any help or info would be appreciated.

If so, see page 22. You don't need to re-flash the BIOS to change the network settings. You just need to change to the settings your current router (ISP) is using.

Wooo....Hoooo!
Exactly the right model. Good to have the firmware update info-- May go ahead & do it since I haven't ever updated its firmware. I definitely should have looked for the online manual. The hard copy manual doesn't even have a pg. 22.
Thank you so much
Best thing that's happened all day
