Latitude D420 Wireless on Vista

Hi Everyone
 
I have a weird issue here....
 
I was running Vista RC1 fine on my D420, Wireless worked like a charm...a few disconnnects but nothing major.
 
Since upgrading to RTM and A02 BIOS Upgrade, I can connect to the Wireless Network using the built in wireless and sometimes I get a "Duplicate IP" (I am the only system on the wireless" and remain connected but no IP address is issued to the system.
 
I tried a third party 3Com card, same issue...
 
Is it a Vista issue or a something else
 
Any insight would be appreciated
 
Cheers

Hi Stuart
 
Just another questions: do you have a broadband modem installed in your D420?
 
I have a Vodafone and wanted to ask you, if you know if there is a driver for the modem for Vista.
 
Thanks for answer in advance!

I have the Sierra Wireless 580 for Telus that I have yet to install because it did not work on RC1
 
So haven't tried it yet

Here is the fix...friend of mine shared it with me who is a Vista MVP
 
reg add HKLM\System\CurrentControlSet\Services\Tcpip\Parameters /v ArpRetryCount /t REG_DWORD /d 0 /f
 
Reboot when completed

Hi!
 
I've installed Vista 32-bit Ultimate and ALL hardware was recognized, incl. the UMTS-card from Vodafone. So I didn't make the reg-key change above.
 
Hope this helps anybody else.

This the hack...I am not technical minded...so can't explain it
 
reg add HKLM\System\CurrentControlSet\Services\Tcpip\Parameters /v ArpRetryCount /t REG_DWORD /d 0 /f

Re: Latitude D420 Wireless on Vista

Hi!
 
I've read about a hack so that the UMTS/3G-modem could be used with any SIM-card and not only with, e.g. the Vodafone one.
 
Does anybody know the hack?

Re: Latitude D420 Wireless on Vista

Wow....it works
 
for all those with this issue on  a d420, run the reg add command given above from a command prompt. Then bounce the notebook, and voila!!!!
 
nice one!
 
Dell & Microsoft please take note of this issue & fix!!!
