Linux and windows networking question

[the.real.me]

Searching around the net this morning I found this knowlegable site and hope someone may be able to offer some advice.

I have a TM-9100 sat receiver that runs on linux and I want to connect it into my windows wireless network via a Belkin Wireless G Gaming Adapter F5D7330UK, my router is a Linksys WAG300N with 3 laptops connected via wireless. The IP of the router is 192.168.1.1, the laptops are set at 192.168.1.51, 192.168.1.52 and 192.168.1.53.

The Gaming adaptor has a 'out of the box IP' 192.168.2.225

I previously had my TM-9100 connected via a crossover cable direct to laptop with IP 192.168.1.51 and it connected to the internet no problem.

Now my dilema, I want to connect the gaming adaptor to my TM-9100 with a short cable, but, when I was trying it out last night I could only connect to either the router or the adaptor, but not both together.

I did try changing the ip address of the adaptor and TM-9100 but it didn't work, at least I couldn't get it to work.

Does the adaptor need to be a different IP to the TM-9100 or the same? I tried both and I couldn't get either one working. I set the IP on my TM-9100 to 192.168.1.10 (for ease of remembering) but have since changed it to various address's without success.

For obvious reasons I want to keep the IP of my router and laptops as they are now, so does anyone know what I should set the TM-9100 and gaming adaptor IP's to?

This is what I have at the moment and can't get it to work

Thanks in advance for any help/ advice and please accept my apologies if I have posted in the wrong section.

Check to ensure forwarding is turned ON on the linux box.
Forwarding is by default turned off on linux for security reasons.

thanks for that, I had already made sure that was done, it seems it may not be a windows or linux problem after all but a wireless one, if I connect the linux box via cable direct to the router it works fine, it's the wireless operation I am having the problem with.

Following extensive hair pulling and cursing, I can now confirm that if I connect everything up via cable (without using the adaptor in the set up) it all works as it should...

When I introduce the wireless adaptor it does not...

Nothing will talk to the adaptor wirelessly, the only way I can access the adaptor is when it is connected by cable.

Thanks again

ok, following more testing, I can confirm everything works fine until I connect the adaptor to the 9100, when I plug in the lan cable, the lan light is lit and the light on the lan socket on the back of the 9100 lights too.

Then, when I try to connect to it the wireless light goes red for a short period (according to the manual this is when it's searching for a unsecured network to conect to) then goes out.

All I have then is the power and lan lights showing on the adaptor but cannot connect to it.

If I connect the adaptor back to my laptop I can use it to access the internet and the rcomputers on my network, it's only when I plug the lan back into the 9100 I have problems, I have checked the settings again, tried cross over and straight cables (I have three of each, they can't all be faulty can they? they do all work when I use them from laptop to laptop or laptop ot router.

To summerise, the adaptor works as it should when connected to a computer, when connected to the 9100 it does not, also I can still connect the laptop direct to the 9100 and that works fine too.
