WINDOWS 8 killing my ADSL connection - Help!

One more question : Are you using IPv4 your internal network, and is IPv6 turned off on the Win8 installs if it is the case?

IPv4 network, IPv6 is ticked (i assume enabled) but no ip settings entered

Remove the tick to disable it completely, for both LAN and wifi.

With the laptop still in flight mode, i removed the tick from both wired and wireless adapter (IPv6) and then took it out of flight mode.

EXACTLY 2 seconds after leaving flight mode, the ping test on my XP machine to google.co.za started timing out and 20 seconds later the router showed a dropped connected. The router stays synced though.....

So you are saying a windows 8 computer added to your network is dropping your adsl line/router connection, your post is confusing. So the router shows a dropped connection, when my router disconnects websites also time out as does everything until it reconnects. Perhaps i have read what you are saying incorrectly.

I am finding it difficult to understand how a new OS could be causing such problems with your network. Have you found out why yet? Can't wait for the answer because it seems so bizarre yet as you say things are fine until the windows 8 computer is added haha.

:rolleyes: @ killa

with computers and software anything is possible

now be quiet while the experts try to figure out what is going on :p


@OP - I gather you have tried the test with both a physical (LAN cable) and wifi connection, and in both cases, the result's the same?

Do you have access to another wifi router (or, better still, a wifi AP) which you can use for a test?
 
With the laptop on, but not network cable plugged in and wifi off, my work network has full internet access. If I either plug in a network cable, or enable wifi on the laptop, the TP-Link wifi/adsl router drops it's adsl connection immediately. It will then try to reconnect after a few minutes which it does, but then drops again. Rinse repeat. If I then remove said network cable OR turn off wifi on the laptop, the router reconnects to the internet indefintely and all my staff have full internet access again.

This is why I am so glad I left IT (I am an MCSE). Extremely frustrating and does not make sense.

@ The_Librarian: I have a Huawei B660 at home and when I first got the laptop, it was locking this modem up to. Killing all of the live tiles solved the problem as I think Win8 was maxing out the connections to the router.

I had a continual ping test to google.co.za running on my XP desktop in order to see the EXACT moment the adsl connection dropped. Far more effecient than waiting for a light to go out on the router or watching the routers web interface.
 
Hmm, this is confusing. Does your work use a firewall installed on a server, or is it a direct connection to the router? If it is on a server, somehow your network card might be trying to make use of the IP of said server thus causing a conflict and then killing all connectivity.

In fact, an IP conflict would usually cause this type of behavior, not Windows itself, the fact that this is a unique error only experienced by yourself is proof of this, as there are no similar cases to be found on the internet.

Try setting the IP yourself to an unused one, and then try and connect it again, see what happens.

The 2 ip's hardcoded to the laptop (wifi / wired) are unique as confirmed by pinging said addresses when the laptop is off.

Network is pc's LAN'ed into a switch and the TP Link is lanned into one of the switch ports. No servers and no DMZ.

It can't be Win8 - my home and office systems on Win8 are rock solid stable, wired and wireless. As I'm sure are millions of others.

Gotta be a configuration issue.

BKACs.
 
Ok, have you tried safe mode with networking enabled? And also stopping all the useless background apps that usually comes installed on new notebooks from running? Also, antivirus software with built in firewalls etc. Just a few guesses, you might have done this already, but I'm stumped.
 
Saw that there is a later version of firmware for the wifi router and the notes say "increases simultaneous wifi connections to 24..." Will put that on and test again. Maybe it's a bug in the router firmware?!
 
I would definitely point fingers to hardware, and a firmware upgrade won't hurt. If all else fails, I would advise you to do the dreaded factory reset on the laptop and install everything anew.
 
New firmware loaded onto the router this morning and touch wood, everything is playing nicely together... will keep monitoring and advise if anything changes.

Thank you for all of your feedback!
 
Yea makes way more sense than blaming an OS, be it linux or whatever. I have heard of issues but crashing networks is a new one :D

Glad it's sorted.
 
I actually have a very similar issue with my Netgear as well. As soon as I max out the TCP connections I get ping drops, slowdowns and I need to restart it to reset those connections. This never happened with Windows 7 and its because the network stack was done over to accomodate for new features.
