You're getting low pings from Linux, and slow from Windows... This might simply indicate that the Windows machine is very busy on its network... The network monitoring built into taskmanager (and perfmon for that matter) is pretty poor on windows.

You could look to see if the windows installation has a clutter of things jabbering at the network for bandwidth - time, update, social networking, driver update services, printer update services, chat clients and internet browsers, as well as music services, file streaming and torrent are all common sources of network traffic to look out for and minimise.

Not to mention remote help/desktop connections - turn them off.

And of course make sure you have no virus, if your Windoze box has become some form of spam zombie for some botnet out there you may well notice very poor network performance as the malicious software hogs the system.

My order of action would be:

1. Check the Windows install for Viruses and malware.
* Try to clean
* Prefer to reinstall it.

2. Confirm the low-pings from a live boot CD.
* Backs your installed distro results assuring you you're not nuts, and proves the invaluable nature of the LXF cover disc
* Also adds weight to the argument to reinstall the machine to stop any reinfection from any installed partition/media back into the windows machine.

3. Get a second/new hard drive and install windows on that, to see if fresh out the box it is still as slow/poor performing over the same network link...
* If it performs well, you really need to think about that reinstall, I'd always prefer a Windows reinstall over trying to fix it...

4. Reinstall the lot...
* Windows first, as a single partition, resize the partition.
* Put Linux back on to let grub modify the Windows boot loader

5. Consider dedicating the machine to Linux and running your windows as a virtual machine within - my oft preferred situation - even for gaming.

Ok it was still having issues after this, so I restarted into safe mode and it was ok. So I disabled all the non m$ services and startup apps.

50 brownie points to who ever can guess which one(s) is causing the problem. I don't know yet...

Well I changed my MTU in windows to 1458 which is what the router came configured with, and at the same time disabled IP v6 and that, touch wood has fixed it.

I wouldn't say it was 100%, but I am loading into a multiplayer online game before it starts, and people aren't jumping around as much

Note to self: This is what I did

Quote:

Open a command line window as an Administrator (ie. right click on All Programs > Accessories > Command Prompt and select Run as administrator) ...
Type the command netsh and wait for prompt
Type the command interface and wait for prompt
Type the command ipv4 and wait for prompt
Type the command set subinterface "Local Area Connection" mtu=xxxx store=persistent

So thanks!

Double check your windows MTU settings.

It's been years since I messed around with this, but I vaguely remember having to drop it down to 1458 on some networks

Sorry, didn't point out that windows and linux results are from same computer (Dual boot)

* New one on order. But still strange ok with linux. Although might be a good time to point out that when I have been using windows, then want to reboot into Linux I have to turn off computer at wall, wait about 2 mins for some capacitor to discharge, then turn on otherwise network in Linux plays up massively.

* Have tried different cable, plugging straight into router.
- Would linux somehow compensate for bt?

* Not on wireless, however flat mates windows laptop (on wifi) has correct ping, and my ubuntu laptop (wifi) has correct ping.

* Again would Linux some how compensate for BT, but then other laptops are ok... Might fire an email off to Virgin as they did change something and tripled my internet speed the other day But then again Linux is fine and other windows laptop is fine to...

Thanks for the suggestions though

Dodgy network connection. Some possible reasons:

* dying interface - though I've never known one decay slowly.
* Wired network - cable (yours or BT's) about to fail - both have happened to me.
* Wireless - congested airwaves due to neighbouring wireless toys,
noise from microwave, neighbour's lightning bolt generator, etc. - has happened to colleagues but not to me personally.
* BT has set up the PoP badly, on behalf of your ISP - has also happened to me.

Results from speettest.net:

Linux (Ubuntu 11.10, 64 Bit) 20-30ms ping

Windows (7 pro 64 bit) 120-150ms ping. Online game have massive lag.

Network Drivers uninstalled, downloaded, installed, reinstalled, updated. Run out of ideas...

Random cry for help on Linux forum... Any ideas?

Cheers
