Adding Range Extender - IP Address Problems

by thomasjoyce / April 25, 2008 2:57 AM PDT

Hi,

I have recently tried to add a range extender to my wireless network so that it covers my whole house. I have tried to set it all up from my XP desktop.
It all works fine whilst the range extender is plugged into the router via an Ethernet cable, but when i unattach them the PC cannot properly connect to the range extender, even though it is rebroadcasting the network.
Please can somebody help me work out what has gone wrong and get the range extender up and running?
I know my post is very long, but i know that people get frustrated when too little information is posted...

Scenarios -

1. Before the range extender was added to the network -

Could connect to the internet via the USR9111 router.
Could view the Router homepage as 192.168.2.1
The IP address (192.168.2.1) was shown as having been assigned by DHCP

2. With the Range Extender connected to the Router via an Ethernet Cable and set up as above, but nothing connected to the PC -

Could connect to the internet via the USR9111 router
Could view the Router homepage as 192.168.2.1 and the range extender homepage as 192.168.2.3
The IP address (192.168.2.1) was shown as having been assigned by DHCP

Could connect to the internet via the USR5441 Range Extender
Could view the Router homepage as 192.168.2.1 and the range extender homepage as 192.168.2.3
The IP address (192.168.2.2) was shown as having been assigned by DHCP

3. With the router, range extender and PC not physically connected and all working wirelessly -

Could connect to the internet via the USR9111 router
Could view the Router homepage as 192.168.2.1 BUT COULD NOT SEE THE RANGE EXTENDER HOMPAGE VIA 192.168.2.3
The IP address (192.168.2.2) was shown as having been assigned by DHCP

When connecting to the network via the USR5441 Range Extender the following happens -

Connection status says 'Acquiring Network address' for approximately 1 minute
Connection Status says 'Connected' and The IP address 192.168.2.2 is shown as having been assigned by DHCP for approximately 5 seconds
The status then says ' Limited or no connectivity' and the IP address is shown as being - 'Automatic Private Address'

i have no internet and cannot access the homepage of either the Router or the Range Extender.

I then dutifully click on repair -

Disabling wireless adapter - 5 seconds
Enabling wireless adapter - 5 seconds
Connecting to wireless network - 2 minutes
Could not connect

Thanks again,
Tom

Adding Range Extender - IP Address Problems

Thanks for the advice. I tried setting the LAN settings on the Router to Static with the following settings - I.P. 192.168.2.10 Subnet - 255.255.255.0 and the Gateway and DNS to 192.168.2.1.

This time when I connected to the range extender it showed that
I was connected to the manual address, but it still would not allow me to use the internet.

Again, whilst the the range extender was connected to the router via ethernet it worked fine.

Cheers,
Tom

Just checked the manual for some APs
by Steven Haninger / April 27, 2008 10:11 AM PDT

I'm installing and configuring for a school. These are 3Com and can be used in a WDS link. However, my manual states that WDS and WPA are not compatible...something about knowing MAC addresses and being bi-directional. I'm still a bit of a newby to wireless or I'd not be reading the instructions. Happy For the school we're using 5 APs and was wondering if WDS would smooth things as far as roaming goes. I'd have to enter the MAC addresses of all APs into each of them. I stumbled across the WDS - WPA incompatibility thing in this reading. I am also wondering if you'd be better off using TKIP instead of AES. I could be way off base here but you might want to look into these possibilities.

It worked, thanks!

Steven,

Thank you very much for posting that advice! I really didn't suspect that the security would be the problem, but changing from WPA to WEP solved the problem instantly. Much appreciated,

Tom

Glad you got it working but something not right
by Steven Haninger / May 12, 2008 8:22 AM PDT
In reply to: It worked, thanks!

I've gone over the manual for the range extender and it's supposed to support WPA which is much more secure than WEP. You'd mentioned WPA/PSK (AES). I am wondering if TKIP was an option in the pulldown. The manual does say "The Range Extender does not support WPA2 PSK or WPA/WPA2 with RADIUS 802.1x authentication...." but doesn't mention TKIP. Another option I'd like to suggest....at least until things are sorted out....that you go with static IP addressing for the extender and your PC. This way you will always know it's address and can get into the web interface with your browser. If you've a discovery utility that accomplishes the same thing, that should be just as good.

Thomas and Steven,

Thanks for this thread. I too was having issues with 5441,

I was able to connect to the internet and surf the web from the Extender(5441) when it was connected to the Router via LAN. However when I removed the LAN cable, it stopped!

Changing from WPA to WEP solved it and now everything is working fine.

Thanks again!
