Internet keeps dropping since update

Hey everyone.
Since the last firmware update with Netgear Genie my router keeps dropping connection, I would notice slow speeds first and when I log in the status would be red as in down. I would then have to press it and it would fix itself. I would also have to restart my cisco thats in bridge mode and my wndr37600v2 to get full 30M speeds again. This could happen 2 or 3 times a day and only starteed since the firmware update.

Any ideas what I can do? Ive took it out of the equatiuon completly now and have the cisco in router mode and have had no problems.

Thanks In Advance

Graham
