V2000 Wireless Problem

Hi,

I'm having a problem with my wireless connectivity. I have sent in my laptop to a HP Service Center and they have replaced my internal Intel PRO/Wireless 2200BG wireless card.

However, the problem still occurs and I would like to see if anyone else can reproduce this problem or if it is just me.

Here is my setup: Windows XP Professional, P-M 1.6GHz, 60GB 5400rpm, Intel PRO/Wireless 2200BG + Bluetooth, and my wireless router is a Linksys WRT54G (54Mbps).

I am certain the problem is not my router. Basically, my wireless speed randomly drops from 54Mbps to speeds as low as 1Mbps inconsistently. It will always return to normal but it happens so often that is is really frustrating because it makes my internet applications stop working. It ONLY happens while I'm on AC power. When I'm on battery power, it works perfectly fine. Drivers are updated. As a matter of fact, this happens when my notebook is completely fresh after a reformat. Is anyone else having this problem? I am using the Wireless Network Connection Status window that you get when you double click the wireless tray icon to watch my speed.

If anyone knows what the problem might be or what I can do to fix the problem, please let me know. Otherwise, I will probably have to send it back a couple of times before HP finally decides to replace the entire unit.

 

Did you try updating the firmware on the router? Do not place the router by your pc or cordless phone. Also do not place it behind anything.

it could be a problem with the "power saving feature" in these cards. You can change it by going to the properties of the device in device manager (right click My Computer, properties, hardware tab)

Hi again,

Thanks for your advice.

I have updated the firmware for the router. I am pretty sure it is not the router's problem because I am able to use an external wireless adapter and get excellent connectivity constantly.

phroenips,

I've tweaked the settings a bit and have been testing the connectivity with the new settings. I made "Power Management" and "Transmit Power" both maximum in the adapter's settings, but I still had the problem. Right now I have set both settings two units below the highest setting and I seem to get a more stable connection although the problems are still happening, just they seem to occur less.

Another thing is that it seems the problem only occurs when the battery is 100% charged.

Any ideas what is causing this? If it is the "power saving feature" then shouldn't other people experience the same thing?

Two possibilities, although remote, are that there may be viruses/spyware on the PC or there may be a browser software issue. I have no problems with my Intel card. It is more sensitive to signal (better signal) than my PCMCIA Linksys card. It even runs faster, subjectively speaking.

Are you broadcasting your signal? If so others may be sharing your bandwidth. I have 3 neighbors who have no security set up and I can easily link on their network, if I had wanted to do so.

If I can buy it in titanium, I will (my bike, my watch, etc. etc.) Why? I hate corrosion....

The routers specifications say that upto 253 IP addresses can function simultaneosly on a router.So Bandwith cannot be the cause of the reduced speed.

Hi,

Yes, I'm pretty sure bandwidth has nothing to do with it. My network is secured and I have 5 desktop PCs in my home that are connected simultaneously with excellent speeds to my router.

I HAVE fixed the problem. I determined the problem was not because of my router or Compaq's hardware. It is Intel's driver. The Power Saving features are not working correctly in the new drivers.

I reverted to a very old version of the driver (8.0.12.20000) and the wireless works perfectly now. I'm not sure if you can get this driver from Intel's website, but I found this driver on a Driver/Application DVD that Compaq provided me with. It was made 3/8/2004 and doesn't have as many configurable settings as the newer drivers. However, it works! and that's all I need. =)

The speed does drop when you are "idle" but it doesn't drop to the point where everything will disconnect. Also, it will only "idle" when you are on battery power to conserve battery.

Hope this helps anyone else who may be having this problem.

 

THANK YOU !!!
It worked I rolled back to the previouse version (the one you noted) and it WORKS.

THANK YOU !!!!

I opted for the 54g Broadcom WLAN card.

It connects immeadiately as soon as my laptop is booted.

Infact it catches half a dozen of my neighbhorhood networks
at very good signal strength.

Since BIOS F.14 came out today, I decided to try and see if the newest driver still functioned incorrectly. It still doesn't work.

However, I tested 8.1.0.28 and it works perfectly.

You can download that here:
ftp://aiedownload.intel.com/df-support/7819/eng/wireless%208.1.1.0%20-%20generic%20tic%2088663.exe

I am currently testing 9.0.0.60 and so far (only tried it for an hour) it has been working fine. This release is not listed on Intel's website, but it can be found here:
ftp://aiedownload.intel.com/df-support/7822/eng/wireless%209.0.0.0%20-%20generic%20TIC%2087621.exe

It has all the advanced features that are in the newest version of the wireless driver.

 

Just my 2 cents --

Most of the routers have Broadcom 54G chipset.

The Intel 2200b/g chip may have compatibility issues with the Broadcom based routers.

Broadcom Wlan works perfectly with these routers.

Try deactivating the wireless zero configuration service, that solve the "frequent dropping connection problem".

 

I now have a different laptop, but I tried the Compaq V2140 and I experienced the exact same problem you are describing.

The only problem is that now I have a new laptop which has the Intel 2915ABG adapter in it and it does the same thing. However, the older v8 drivers don't support this adapter, so I'm wondering what to do.

I'll try that v9.0.0.60 driver, in case it's older and works better than the one currently installed, but otherwise, I'm pretty much at a loss.
