Arris tm3402 ongoing problems
I recently had my phone service changed to VoIP. They installed an Arris TM3204 modem.
The first modem the tech installed would link correctly on the WAN side with all right lights on the front and the phone working. But, it would never hand out an IP to my router.
We connected my laptop directly in place of the router, and it would still not give an IP address. The tech replaced it with a new router and the LAN IP problem seemed to be fixed.
The phone works fine but my internet keeps going down. The modem is connected to an Netgear NIghthawk R6700 with the latest firmware. The internet drops out now about once per day. The status lights on the modem continue to indicate that the internet is connected. Power cycling the modem fixes it and it gives out an IP again on boot up.
Cox did a truck roll for the problem and the field tech replaced the modem with a different one (so I"m on my third one). It worked for most of a day and now is doing the same thing.
Hard to believe there are 3 bad pieces of hardware in a row. But nothing has changed on the LAN side and it won't hand out DHCP to router or laptop.
Any body else experience this or have any ideas?
Should I go back to my previous modem? I don't really care about the VOIP and can use OOMA instead.
