Question

ASUS WL-520GU Router - Invalid Dynamic IP address

Asked by: ijourneaux1

I am trying to switch out my router from a simple TrendNet router to an ASUS WL-520GU so I can try out DD-WRT. Unfortunately I can not get it to work for more than a few minutes.
I am using Charter Cable as my internet provider. Normally hooking the cable modem up to a router is as straight forwoard as it gets. I have used several different routers over the years with no difficulties.
The WL-520GU is not proving so easy. If I start with the router as a fresh reset to factory settings, I can access the internet for a short bit of time before the router will start complaining that I have an invalid dynamic IP address or check the  DNS settings. At this point nothing I do will restore the access to the internet short of going back to factory defaults and starting over. I have the lastest ASUS firmware installed. Until I get past this, I won't try  any of the thrid party router software.

All of the settings look fine. With Charter, I don't have to enter a username and password and I don't have to use pppoe. What is going on and how can I get around the problem.? I can plug the TendNet router back in and everything works as expected.

Did you clone your PCs MAC address on the router? Most modems are set to act as a transparent bridge to your router device / computer and are linked to the MAC address.

Did the router come with a setup CD? If so you should run it and it should take care of that for you.

I ran the setup that matched the firmware version. Unfortunately to no avail. It looks like the internet works for a short bit. Then if I restart the router, I get the Invalid Dynamic IP address. Though all of this, the mac address displayed in the router configuration is un changed.

Did you already upgrade the firmware in it to the latest ASUS has?

 

by: ijourneaux1Posted on 2008-12-29 at 21:53:57ID: 23260831

It turns out it doesn't seem like I  was doing anything wrong. ASUS finally got back to me and indicated that the router wasn't correctly saving its settings when it was rebooted. They asked that I exchange the router,

The problem existed with the original router firmware. That was the reason I upgraded the firmware to latest version.

Sorry for taking so long to post.

Unfortunately in this case, the problem was a hardware problem with the Router. Every time you madea change to the router configuration, it would generate this error. The temporary solution was to change the MAC address of the router, reboot the router, change the MAC address back and reboot again.

The router would work flawlessly until the next time I had to change the router configuration.

I have a second identical router that does not have this problem.
