I'm trying to diagnose a problem I'm having with my home network. My setup is basically a Arris TG862(I think), which is currently acting as cable modem, router, DHCP server, and firewall. Into this I have two desktop computers and a second device (Netgear WNDR3700) which is running DDWRT and is setup to act as a wireless access point and switch. There is one desktop PC plugged directly into it, and a number of wireless devices (phones, laptops, etc).

Anyway, I've noticed some internet outages. During these outages if I try to ping something e.g. Google DNS at I get probably between 80-99% packet loss, and when the packets aren't lost I get wildly erratic ping times between 60 and 3000ms. I found that if I unplugged the wireless access point, this goes away. I did some more testing and I found that this would happen if I got on my phone and opened Speedtest.net. During the portion of the test where it tests the upload speed the internet seems to die on my desktop computers. I tried doing the same from a laptop, both on wireless and connected directly to the Netgear, and it didn't seem to replicate the same results as the phone.

So at this point I have no idea if this is an issue with the Arris unit or if this is an issue with the Netgear. :confused:
