unable to contact dhcp server

Hi! I was hoping someone can help. I'm not overly computer literate but will do my best to explain my problem. I'll start at the beginning as I don't know what's relevant and what's not.

Ok last Thursday I contacted Telstra, our internet provider and arranged to upgrade to ADSL2. They said it would take 3 business days but by 5pm Tuesday evening you should be set to go. Come tuesday night we couldn't even get on the internet let alone take advantage of supposed faster speeds. After speaking to Sales at Telstra, they said I needed to change my password so they changed it for me and then and then I called Tech support to find out how to actually change it on my pc. When they took me through the process, it wouldn't accept the new pasword from my end but it was being recognised from their end. Anyway they said they would get a technician to look at it and call me back the next day. I ended up calling them Thursday night and I realised that my pc wasn't recognising an IP address. Finally I had a technician call me today and confirmed that it was an IP address issue but that it wasn't anything they could help me with, I had to contact the people who Igo through for the wireless connection. Since then, I have been trawling through forums trying to find out how to get an ip address for my wireless connection.

So far I have tried ipconfig/release and renew, ipconfig/registerdns, and a couple of other things which I now can't remember. Basically I have a emachines pc, an adsl modem, a RangeMax Next Wireless-N USB adapter WN111. My phone port is at one end of the house with my desktop pc at the other, hence the need for wireless. I don't have a cable long enough to be able to check if the internet works with a cable.

I think that about covers it. My problem is that the internet is not working as it is not recognising an IP address. If I try and renew the ip address the error message 'unable to contact your dhcp server' comes up. Can you please suggest some things I could try?

Many thanks!

You say you have a wireless provider which is not your internet provider. Can you explain that confusing statement?

Hi wanderer, thanks for replying!

Ok, I use Telstra as my internet provider. As I use a desktop pc, I need to use a wireless adapter which is from Netgear. When I install this adapter I am given the option to use either Netgear or Windows as support for the wireless. I have always just used Netgear as it was recommended in the setup but last night as I was trying different things I reinstalled it several times trying both Netgear and Windows as the support to see if that made a difference to this problem. It didn't.

Does that make sense now? Sorry about that!

"I have a emachines pc, an adsl modem, a RangeMax Next Wireless-N USB adapter WN111"

I see no mention of you having a wireless router.

Perhaps your adsl modem is also a wireless router?

If you don't have a wireless router you can't connect wirelessly to your network. Without a router after the modem you can't get any more devices on the network.

I guess its a combined modem/router then as we have been using this setup for a year now and there is no other piece of equipment involved.

The modem brand is Thomson TG782T if that helps.

Where are you located ?
Australia ?

"The modem brand is Thomson TG782T if that helps."

It's NOT a standalone ADSL modem - it's a combo ADSL modem / wireless router.

Thomson TG782T

"Custom version of the TG782, supplied by BigPond. Firmware locked to only allow authentication on Telstra/BigPond domains."

It supports ADSL2 connections.

User Guide / Manual:

It's loaded by default to the C:\Windows\Temp folder
Click on the floppy icon top left to choose to save it to elsewhere on your hard drive.

There's lots of troubleshooting info in it.

The rest of the content of this post was deleted - after I saw you posted the following post, apparently you don't need it.

Thanks for your help everyone but I've finally resolved it! Very stupid really but easily done I guess. It ended up being an incorrect number I was typing in. On the Netgear Smartwizard where you go to set up the wireless adapter, I had to put in the WPA-PSK key from the base of the modem. Instead I was putting in the password that Telstra had given me to access the internet or set up the internet or whatever I used that number for! After all this time, my mind is a scramble and I can't think. I've spent from 2pm yesterday until 1am this morning and then from 9.30am today until now trying to sort it out, doing ipconfig/renew and who knows what else to my computer trying to resolve it and thats all it was!!!!! So silly!!!!!!

Anyway, thanks again!
