Wifi and laptop trouble

This is the hardware i have

Dell Inspiron laptop running Win XP Home having an Intel ABG wifi network adpater
Dlink 524 wifi router

Everything was fine a few days i could connect to the wifi network at home via the laptop without a problem but starting a few hours back i am unable to get an ip on the laptop.

I tried to disable the wifi adapter but was greated with a BSOD which said driver_corrupted_mmpool. I thought maybe its a corrupted driver issue so went into safe mode uninstalled the wifi drivers and reinstalled them.
But still no luck :@ :@ still the laptop can find the wifi network but cant get an ip. So i tried resetting the router but still no luck.

Then i tried to manually enter the ip n gateway details on the latop, it then showed as connected but when i tried to ping the gateway i was getting request timed outs.
And if i select obtain ip manually then again its unaable to get an ip.

BTW my HTC P3300 can connect to the wifi network without a problem.

Any help will be really appreciated :)

TIA
 
Do you have a cross cable handy ?

1) Connect via LAN and check if your laptop can get an IP.

2) Moreover check if the network icon appears on your taskbar or not. Might be a issue with the network stack.

3) In case the laptop is able to get the IP when wired then its purely something do with the the WiFi.....also consider a 'hard' reset on the router via the reset button it would have......

4) Did you try safe mode with networking?

5) Do you have Mac ID filtering "on" on the router? Check if it got enabled.

6) Mask your HTC phones MAC id to your laptop and assign the laptop the same IP address it would acquire ( via DHCP ) and see if lappy works.
 
Damn!, those are some good tips hanzy :)

@ wraith : you might as well as try this.

To reset Internet Protocol (TCP/IP) in Windows XP :

At the command prompt, type the following command and then press ENTER:
netsh int ip reset c:\resetlog.txt

And this is if you do not want to specify a directory path for the log file, use the following command:
netsh int ip reset resetlog.txt

Also try : ipconfig /release (enter)

ipconfig /renew (enter)
Also : If you want to know what your WAN IP is, so that if you want to manually set an ip address try attaching the modem directly to your laptop and go to :

What Is My IP Address? - IP Address Lookup, Internet Speed Test, IP Info, plus more

Tried those suggestions but still nothing...

The only consistent thing so far has been that the wifi adapter can find the wifi network but cant obtain an IP and everytime i try to disable the wifi adpapter on the laptop i get a BSOD saying driver_corrupted_mmpool.

I have tried re-installing the drivers but its been no help so far....i am going to try and install a fresh copy of windows...hope that works.

Or has the wifi adpapter on the laptop gone kaput?

did u try safe mode with networking ?

boot in safe mode > msconfig > disable all startup items.

boot in normal windows and try the same.

p.s. : installing windows on another partition with all drivers will take approx 1hr and will help u exactly know if its software / hardware related.....leave the router as is , its fine. btw when u connected via LAN did u get the "Network" icon in your systray ? (this is important)

@BackToExistence : thanks !

I didnt get what you meant by "Network" icon but i am guessing its the Local area network icon then it does appear...

my bad for not being precise , yes i have been talking about the same.....well if the icon does appear then even the registration stack seems fine :-s i suggest u try the safe mode option as i quoted above , else please go the new OS installation way to narrow down.
 
Well nothing seemed to work so installed a fresh copy of windows and now everything works just fine....

damm those corrupted drivers!!

Thanks all you guys :D
 
The same problem is happening again....the drivers have been corrupted again!!

This has never happened before...i am wondering is the laptop going kaput as its almost 3 yrs old and has been used like a desktop for most of the time...
