Having IP problems connecting devices to my router
« on: July 06, 2011, 09:20:23 PM »

Hi everybody!

First I would like to say that I'm sorry if there is any other post with the same problem, but I truly search for it, and I couldn't find it.

The problem that I'm having is basically that my router isn't giving right ip addresses to my devices. I've tried to connect a wireless printer (HP for doubts) and the router gave a 169.254.XXX.XXX ip address to it. If I unplug/plug the router, the problem is solved. It can also be fixed by using the "reboot device" tool that the router has at the configuration page. But this only works for some hours, so it isn't

Now, it isn't a printer problem. It has also happened with some notebooks, with around 5 to 6, not all of them.

I've tried changing channels, resetting the router, changing password, security password type, changing firmware (present is 3.11NA H/W C2), and nothing can fix it.

Please help!, I've been dealing with this for over a year.

Thanks!.

!69.254 means that the device is self assigning its own IP address since it could not get an IP address from the router in a period of time.

What HW version is your router?

What ISP Service do you have? Cable or DSL?
What ISP Modem do you have? Stand Alone or built in router?

Ensure DNS IP addresses are being filled in under Setup/Internet/Manual?
Turn off Advanced DNS Services if you have this option.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices on the router.
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP.

What wireless modes are you using?
Try single mode G or mixed G and N?
What security mode are you using? WEP, WPA or WPA2? Preferred is WPA2.
What wireless devices do you have connected?


Turn off all anti virus and firewall programs on PC while testing.
Turn off all devices accept for one wired PC while testing.
