asked on

Network Slow one direction only - need help !!

Hi all experts,

I have been dwelling my problem too long and decided to ask the experts here. My NIC seems to slow in one direction only. Firstly I thought the problem would lie on the bad NIC. I changed it to a new one, but it is the same . It seems that when I transfer file back to my Fedora Core file server, it goes like a blink of an eye for 1mb file. However when trying to get files from my server back to my Windows XP pro (SP2), it takes a lot longer, may be a minute or so. I also realised when downling the net (for example skype.com) the speeds seem to be capped at 30 - 35 kb/s, but when done on my fedora server, it goes up to 2000kb/s. This tells me nothing is wrong with my router.

I tried to changed my NIC setting to full-duplex instead of auto-sense but nothing had changed. Also tried to update the driver, the problem persists.

Now I am not sure what the problem and almost give up at this point of time. I realised that if I re-format the computer and the problem will go away. But I am not willing to do so, unless there are really no solutions.

Other tried method:
Using Winsock to repair IP stack layer..........didnt work
Changed NIC.................................................didnt work
Update NIC driver .........................................didnt work
Uninstall WebJet admin from HP printers......worked!!! but when computer is restarted the problem persists


nb:
I also have a wireless laptop accessing the same router (its a DSL G604T - router modem wireless combo) and It accesses with a great speed

Please help

Thanks

You could defragmenting your hard drive.  At a command prompt run:

defrag c: -f -v

Another option would be to temporarily disable the Windows firewall or any 3rd party firewall you may have installed and test the file transfer again.

Hi Chakote,

I have defragment my hard drive (I should've put it on my original method), and I dont have any firewall, never used windows firewall anyway, the only protection that I trust is NOD32 anti virus system. And for further information, I have been using this anti virus before the problem arose. Plus my laptop where I access my wireless connection is also protected with the same anti virus
I see you've changed the NIC, have you tried using a different network cable?
Yes i have
I'm not quite sure what you mean by "Using Winsock to repair IP stack layer" have you tried the following:

Well, I think there is not much I can do at this moment, and if there is no possible solutions I think i might need to re format and build my pc again
try uninstalling the last installed piece of software (other than network card driver)
You know, I did installed the webjet admin (web based network HP printer monitor) before Posted this question, and it worked. However when I restarted my computer the problem came back. So I thought there must be something to do with Windows services that gets started automatically.
If you're going down that road, try disabling any non-Microsoft services and see if the speed improves.
Hmm, I think I will do that tonight when I'm home, really appreciate your help
Guess what, I couldnt help my mind dwelling whether or not the suggestion that you gave me works or not, so I hit vnc and connected to my home, stop all services that are not Microsofts' except NOD32 and VNC (I did stop NOD32 a couple of days ago, but nothing changed). The problem persists. My download seems to be always capped at no more than 35 kilo byte/ sec. This applies to both internet and accessing files across my linux file server. However my upload is great / normal. My VNC connection from work to home still at great or less delays. Upload files from my problematic computer to FC server still work on the fly.

That is my latest update
