Dell Laptop Wireless Issue (DHCP not working)
Hi
I've got a Dell Inspiron 1750 causing me a headache. I've already done the following, but without success:
Full AV scan
Full spyware scan using Malware Bytes (found a few bits)
netsh int ip reset
netsh winsock reset
Reinstall network driver using latest from dell website
Tested using manual IP on the wireless adapter (this works, its just that it wont't pick up a dhcp address)
and, I'm currently on the wired link using DHCP which is also working fine.
I've done all the things I expected to do to fix the issue, still remains. What have I missed?
Thanks.

Dose the computer in question get an IP when connected to other wireless AP's? Maybe their is a setting in the router that only sends DHCP requests to the lan only.
It is possible that your actual wireless card has gone bad. I would try the following:
Uninstall the wireless card, shut down, and then remove the wireless card. Re-seat it, check that both antenna wires are properly attached to the card. Start up and install the new driver again.
If this does not work, try another card. (See if you can borrow one) .... Thinkpads_User

I have seen a similar situation that was fixed by changing the negotiation from AUTO to 100MBS on both the router and the NIC. Alternately, make sure they are both set the same. kevin

dont think the wireless card is faulty, because putting a static address in means it immediately gets internet connectivity.
changing to auto negotiate speed isn't the issue here, firstly we're talking about wireless and it does work at 54mbps with the static ip.
the router issues dhcp address fine on the wireless, 3 other laptops no problems.

In a situation where wired works and wireless does not (at least not properly), the number of trouble points is limited.
I suggest you try the following:
1. The steps I laid out for the wireless NIC to reseat it.
2. Make a record of your router settings, do a hard reset, upgrade the firmware if you can and set it up again.
3. In Windows, delete all the wireless profiles, restart again.
4. Now try setting up a brand new wireless profile.

This is going to be a really dumb question, but did you check the router to see if you have MAC Address filtering enabled on your wireless router? If you statically assign an address to a WAN card and have the the right Wireless Settings on the adapter, you will be able to connect to the wireless router (I believe..), but you wouldn't be able to "Route" anywhere (i.e. the internet).
But if you have the right wireless setting on your system without having the MAC Address of the WiFi adapter in Wireless MAC filter on your router, then it will attempt to connect, but never get an address. For troubleshooting issues like this, you may want to try and disable MAC filtering on your Wireless Router.
What model Wireless router do you have?

Yep, it is a Broadcom based device. I connected to a BT FON network that is within range (no encryption) and this does indeed work.
Thanks for putting my mind at rest that it wasn't me doing something wrong.
