I had to replace my AT&T DSL modem that I got in 2007. The AT&T tech installed a newer Westell modem. Immediately my wireless network died.
Like everyone else I know; I use a Linksys wireless router.
Turns out the dumb asses at AT&T put a router and DHCP into the DSL modem. :mad: They must know the majority of users buy their own third party routers. Way to go AT&T. Crash home networks all over the country.
Took me two days to track down the answer. You have to configure the Modem into bridge mode to turn off AT&T’s stupid internal router & DHCP. Some modems have a weird option, PPP Location that has to be set to “Choose PPP is on the computer, gateway or router radio button.” to get into bridge mode.
Forgot to add… There is an alternative fix. Change the default base ip address of the router. Because the DSL is using that address for its own internal router.
But, then you gets these weird page timeouts every few minutes surfing the web. Also, I discovered I couldn’t open any ports for gaming.
I never had any problems with the first AT&T DSL modem that I got in 2007.
There was one key trick. I had to power up the DSL first. Wait for all the lights to turn green. Then plug in the Linksys router. Otherwise it wouldn’t work. I’m pretty sure that modem didn’t have an internal router. There was no ip conflict on 192.168.1.1 (the routers address)
You can usually disable the internal router. And, frankly, I don’t believe they even make DSL modems that don’t have routers.
And, finally, how incompetant are the people who set it up that they didn’t know to give it a different IP if they were going to set it up that way? Its IP should be outside of the DHCP range. Then again, your router shouldn’t be giving out an IP its already connected to, no matter what the IP is. Heck, it should automatically change its own IP if there is a conflict.
