Slow Network Performance

[mufaa]

I am getting extremely slow network performance from yesterday, and all of a sudden. I am connecting to a WinXP machine, the file transfer is slow, accessing files and folders is relatively fast but there is some slight stutter while exploring, right clicking takes a while, and accessing it via remote desktop software UltraVNC is slow as well.

I don't know what happened. I have restarted both the computers. I checked all my NIC settings. I can access it fine via another PC running Vista. So it is a problem on my end. I am fairly sure it is not my NIC. Internet/Downloading is fine. It's just the damn network. I haven't changed anything.

Please help!

Yup, that's the first thing i did!

how abt ip6 did you turn off ip6 support? is it slow on your lan? and the internet is ok (browser, email, etc)?

Kind ain the dark so forgive the dumb questions
Ken

Turned off IPv6 now, but no difference. And yes, internet is fit and fine. It's just the network.

Update on my problem:
It's the bloody router. I think. I have 3 pcs connected to it. Mine, the XP machine and my bros. Now, if i remove the lan wire of my bros pc from the router, the network access becomes normal! If i plug it back in, it becomes slow again. It does not matter if my bros PC is turned on or not. Just the presence of a 3rd lan wire complicates my connection. I have tried this 4-5 times.

So is it the router? I would say yes, but my brother has no such problem. He can access and view files normally. So it's a combination of Win 7 and my router that's creating the problem. Maybe you guys have an idea?

hey

Glad you may have found something.several possiblities. nic on your bro's, cable, etc.

have you tried mixing up the cables, then the ports on the router, etc.

That would help you narrow it down. sometimes a 10 meg nic on a 100 meg link will slow the entire segment down. Something wlse you can do (yeah i know the slowdown is on the lan) is to run a ping from yours, the xp, and your bros. they should be the same in the first 2 steps (mac, and router).

Sorry we haven't been more helpful but alot of times it takes someone to worry it to death like you.

I still jump back in anytime this thread gets a post

Hey, thanks a lot for your help man. Hopefully, we will be able to figure it out somehow.

I have tried different ports on the router, but the result is the same. If only mine and the XP machine are connected, it works fine. If another PC gets connected to the router, it immed. slows down. Very odd.

I am not sure if it's my bro's NIC because it does not matter if his PC is shut or ON.

How do i run a ping from PC to PC?

 

[mufaa]

Well, i pinged to my XP machine:

Seems fine.

ping

Seems fine.

Ping is fine but one thing I did notice is the IP 192.168.254.69. Is that from your router or the ISP? your router if it is a nat router should be supplying inside IP' like 192.168.1.101

Ken

 

[mufaa]

It's from the router. ISP IP address is completely different from that. This is the IP address router assigns to PCs. In my router you can change the XX in 192.168.XX.ip. When i got this router, it was set to 254 by default and i thought wise to not tinker with it. The reliability of my ISP and their marked products is ZERO.

I think i may have solved it. My bros and the XP machine's lan wires connect to a socket in my room which leads to the respective rooms were the two PCs are (i don't know the technical term for it). I pulled them out and plugged them back in...and now it works. Unless i screwed up my bros connection, lol. It seems to be working just fine.

I can't believe the solution was simple as this. I am hitting my head right now.

But I bet thats the first thing you check next time

Ken

 

[mufaa]

Well, you got that right. The network still isn't the same as before. There is a slight hesitation, a slight stutter when i open a folder. Well, i will take it as long as it runs.

Thanks for all the help Ken!

****...it turns out...my bros LAN is gone. So that's why it was working. ****.

lan

Is there anything wlse on his lan? when you said it was conneted thru a thing was it a switch or a splitter?

Ken

 

[mufaa]

Err...i would say splitter, definitely not a switch. It's a socket that takes lan connection, which extends it to other rooms.

Well, anyway. It seems to be working anyway. My bros LAN is working and the network access is fine for me. But right now, his PC is ON. I wonder what happens when it will be turned off. That's what i want to see. Time to wait till he shuts it. Weirdly strange problem. No wonder google has no answers of it either!

One thing you can try is to dl something big (a torrent or large file) and see if the dl rate changes with your bros comp unplugged then plugged then on. if the rate stays the same your fine if not bros comp is putting a load on the lan

glad you are fixed

[mufaa]

I am always downloading something or the other. The speeds have always remained invariable. In fact, i had downloaded a large demo last night when my bros PC was shut off. And right now, i am at it on another demo with my bros PC turned ON and the speeds are the same.

 

[mufaa]

Alright, confirmed. If my bros PC is on, the network access is fine. If it's turned off, the lan wire is connected to the router, the network becomes slow. Now, what the hell could be the problem! It's as if my bros PC is 'helping' my PC to coupe with the network access speed. I don't think its the router. Has to be a setting in Windows.
