File download cannot complete with Z61t

micro_1 · #1 Post by **micro_1** » Sun Oct 28, 2007 11:47 am

I have my Z61t just over a year. I was unable to connect the notebook to my Dlink DI-524 wireless router with the internal Intel PRO/Wireless 3945abg wireless adapter even when I got it brand new. Hence, I was using a Dlink USB wireless adaptor for wireless connection in the last year.
The problem is that this Dlink USB adaptor is so "FAT" that when I plug it into the vertical USB socket at the rear right side of the notebook, the computer will be unable to stay flat on the desk (with the rear right corner lifted up). If I plug it to the front right USB socket, then it will block the neighbouring socket as well (that means I cannot use the neighbouring USB socket for anything else). I ended up plugging in a PC card USB hub to add USB ports for all other connections.

Until recently I came across a blog at the below link about solving wireless problems with IBM Thinkpad, I seemed to have hope to restore the internal Intel wireless adaptor.

http://trivialproof.blogspot.com/2006/0 ... -with.html

Although the description was for a T60p, hoping that this might work for my Z61t also, I followed exactly the description in the blog. At the same time I downloaded the latest relevant drivers from Lenovo site and completed the installation.
Fortunately, the internal wireless adaptor can work now and I can do away with the Dlink USB wireless adaptor. I have no idea whether the credit should go to the latest driver software or the procedures described in the blog.

I was surfing the internet happily for more than a month with no problem "discovered".

But in these few days, I came across a problem with the Intel wireless adaptor again. When I download an email attachment file (just less than 4Mb) containing photos from my daughter, it just keep dropping out midway and downloading only part of the file. The same thing happened for several other emails with attachment files as well.

I have checked the wireless connection and carried all diagnosis with PC-doctor as recommended by Lenovo. Everything is ok and no problems found. I even tried updating access connection to the latest 4.42 version, but still no help.
Does anybody has similar experience? I would appreciate to share any thing to resolve the problem.

I had similiar problem with my t43p showing the same systom as you.. sometime wireless load up and most of the time don't work, and i load multiple driver for it and seem to get worse. This is because the drivers installed is still in the system, even tho you tried to uninstall or delete from devices mgr, it still somewhere in the system.. However, you can try the method shown on the following link.. let me know of the outcome.

Thank you so much for the info anyway.

In fact I did the update immediately after a fresh clean recovery of my Z61t. The reason is that I have already tried a lot to update, uninstall & update again previously. It just made the situation even worst as you said.

I am still trying to find a way to solve the problem if possible. I have checked the Lenovo site for updates but it seems that nothing new had came out. So it has to be somewhere else on the web.

are you using Access Connection?I had similarly problems whit AC and various drivers. Try to uninstall AC then use windows wireless or try the latest drivers form intel support site. In most case drivers form lenovo site are not up to date but they compatible whit helpful programs that you got on your laptop.

Thanks a lot for your info. I have tried uninstalling AC and no change in problem. Then re-install AC version 4.42 again but problem remains.

I'll give a try to the Intel driver on top of the Lenovo driver.

A couple of questions.

Were you able to download large attachments using the D-Link USB adapter?
What email client are you using? Some email clients time-out on a large download.
If you are using your browser to get email, which browser is it?
Do you have a key timeout setting in your router configuration?

micro_1 · #7 Post by **micro_1** » Thu Nov 01, 2007 10:12 am

1) There was no problem downloading large attachment files using the Dlink USB adaptor.

2) I use gmail and there was no problem in the past year. I guess the problem is not associated with timeout setting because the download drop out at different time, i.e. say I have an attachment file about 3.8MB, and it dropped out differently each time downloading may be 2.4MB, 1.8MB or 3.1MB etc. Anyway the behaviour is different each time.

3) IE7 with setup for Google (only updated recently).

4) I am not sure about timeout setting in the router configuration but there is no such time limit with the Dlink USB adaptor that I used before. But I'll check again the router with your suggestion.

One thing I had to mentioned that the Dlink DI-524 wireless router can be configured to work on any 1 of 13 channels, but the Intel PRO/wireless 3945abg adaptor will not work on channel 12 & 13 (1 to 11 is ok). That means if I set the router to channel 12 or 13, the Intel wireless adaptor will not see existance of the router even I put my notebook side by side with the router.

BTW, I have tried updating with the latest Intel driver version 11.1.1.0 but the problem (drop out) is still there.

I would like to thank everybody here for their suggestions to help solving my problem.

Lets recapitulate things so we know/don't know and what we/you have done :
1. Brand new windows - its not win problem. right?
2. Work fine with dlink usb wireless - everything works fine with other adapter...
3. AC reinstalled and new version installed - we cant blame ac for this

4. Drivers/bios/firmware are up to date? - are they?
5. timeout? - works with dlink usb adapter... so its not timeout...
6. dropping out? - are you able to browse www? do you loss your connection to router? can you download some other staff form other pages?
7. do you work on battery's or whit ac adapter?
8. wireless led on ThinkPad, in moment when problem aper, blinking or continues lighting?

I think the problems are in one of the following:
Adapter failure,encryption/decryption,router firmware,power issue,bios/firmware

1. The first thing that you must do when you get email form support they will tell you must have latest drivers and firmware (router also).
here is the link for DI-524 firmware (look for revision code then look for firmware version)
http://support.dlink.com/downloads/

2. Try without encryption or mac filtering, disable all security.

3. Disable all power save modes for adapter (under drivers and bios settings, check the router for similar config)
check this http://support.intel.com/support/wirele ... 006205.htm

3. If that don't help you, went to ibm service

cheers

btw sorry for my bad English its noth my native language

Thanks a lot Zonzisa for your passion to help, you are not alone, my native language also not English.

Your suggestions are very comprehensive, I'll try them to see if I can solve the wireless problem.

Your point 7 reminded me about the battery. I usually unplug the battery and use only the transformer because I am lucky that mains power outage by accident is rare in my area (not happened for the last 4 to 5 years).

Symptom of download problem

I use IE7 to login gmail as usual. Check my mail and download the attachments. When I click download in the mail, a new dialog will open asking "open"ing or "save"ing of the file. If I select "save", another dialog will open and let me select the destination folder. Pressing OK will start the download. The thinkpad wireless LED blinks along with the download. The download dialog will show the estimated time and the progress. Only that it will stop download (somewhere midway) and show you that it had been completed. Checking the saved file and I find that only part of the file had been downloaded.

I'll try some other ways to trace the problem and will post it here if solved.

I use the Opera browser. Usually you can restart a download if it gets stuck or stops without starting again from the beginning. You might want to consider giving the Opera browser a try and see if that helps (it's free).

I shall try opera, thanks for your advice.

Hello All,

I would like to thank everyone here to help me solving the thinkpad wireless problem. I have tried nearly all the suggestions and should need to come to a conclusion.

1) I tried fitting back the battery. It just made no difference to the problem.

2) I tried to find driver update for my DI-524 but none is available for the version I am using.

3) I tried disabling MAC filtering & security encryption. Also no help.

4) I tried disabling the power save polling (PSP) as recommended by Intel. It seemed to have a little help, but still cannot eliminate the problem completely. I have 1 success out of three downloads (the same file).

5) I installed opera and have no problem discovered so far. I tried to download the problem email attachment for several times and none of it has the drop out problem.

Now I switch over to opera and abandon IE7.

Besides my "powerword" (a Chinese dictionary software) also doesn't like IE because it will shutdown IE everytime when it starts.

regards,

micro_1

If this problem is permanent then look into your firewall settings, configure it to accept TCP connections to the required ports.

Thank for your help Zonzisa.

I have upgraded the F/W version 2.06 but the drop out problem still exist.

Check in Internet Options in Windows. There is a setting to allow passive FTP. Perhaps this will work for you.

Activating Passive FTP Mode

Passive ftp has been enabled. Thanks

I have no problem connecting to other ftp.
