Exactly every 600 seconds (10 minutes) my 2wire 2701HG-B has latency go from around 15ms to between 400ms and 800ms. This lasts for between 108 seconds and 113 seconds averaging 110 seconds.
This is true for both wired and wireless. I've tried it on multiple computers and it is still the same issue.
I disabled all wireless encryption and it didn't help. I restored factory settings, put back the bare minimum, and it doesn't help.
Does anyone have any ideas? Much appreciated.
