Good to see that you have some solution to your problem.

I do not think it is a firmware issue on your wifi router - 2004 is not that old especially considering dhcp came into existence a lot earlier than that.

Now that you have given more details of your set up, it looks more likely that this is more a routing issue.

Are you routing between the two routers or bridging the two? If you have two networks then the dhcp broadcasts from your LAN will not reach the dhcp server on the other network and this may explain why it does not work. Easy to check this - plug the PC directly into the wifi router (you will not be able to access the Internet but that is beside the issue) and see whether you can get a ip address.

Anyway, the only way to determine the problem is to sniff the packets on the wire - you should be able to download and install wireshark now that you have an Internet connection.

I'm using my wifi router as just a switch & wireless access point.
My main router is on another floor.
I've hooked numerous PC's up to the wifi router & have my main PC hooked up to it & they all receive an IP through dhcp.

Plugging the laptop directly into my main router still doesn't give me an IP so it isn't anything in between on my network.

I also forgot I can put my DSL modem into router mode and use that as my dhcp server as another option.

For wireshark, if I connect staticly & then run udhcpc to see what happens will it show me what is going on when the PC looks for a DHCP server?

also,
if I recall correctly, Slitaz 3.0 used to work just fine on my network.
I'm going to boot up that CD & see what happens.

Now, if it doesn't give me an IP through dhcp then i'm going to just reset my router & clear the settings because there is a lot of old stuff in there & I may of done something that is causing it to ignore the client.

If it does work then I can use that to compare the two to see what is going on differently.

I'd prefer not to take the easy way out & figure out what is going on.
It'll take longer, but i'm learning & do see the potential of this distro & would like to stick with it.

thank you for your help.

Ok, slitaz 3 doesn't boot into X on my laptop but when I ran tazx it downloaded the video drivers without me doing anything. LOL!

I can't get to a desktop, but I have internet at the command prompt.
So what is different with networking between Slitaz 3 & 4 ?

@nitrogen_widget,

With regards to your question on wireshark, yes, it will show the dhcp requests going out and dhcp responses coming from the router, if any. Also, udhcpc has some extra options you may want to try - I would run udhcpc in the foreground so that the process can be repeated, if needed.

It may be worthwhile saving the trace so that you can compare with a Slitaz 3 trace.

Also, while you got wireshark running, you may want to try out the dhcp-client which is available on the repo. This should give you sufficient info to draw any conclusions and hopefully come up with a good solution.

With regards to difference between Slitaz 3 and 4, probably someone like mojo will be able to provide you with an answer. I am just a Slitaz user and not involved in the development cycle so sorry, cannot answer that question. As wild guess, I suspect 4 may have an more up to date udhcpc script.

If I read wireshark correctly, the broadcast to any dhcp servers went out & my router did nothing. It was like it wasn't there. I don't know why, but even with my laptop plugged directly into my router I still couldn't get an ip address.

I was going to troubleshoot this further but decided i just don't have the time to play around with dhcp clients & just made my dsl modem my dhcp server & I'm posting this now from my fresh laptop install of slitaz with working network at first boot.

@nitrogen_widget, this is very strange but at least you have a good working solution. If you do find some spare time, it may be worthwhile comparing wireshark traces when running Slitaz 4 and one of your other distros (or alternatively, running a different dhcp client) - just curious to know what is going on!
