Hi all,

Got a 5-port Netgear switch in my room which I was using to split the Ethernet cable coming through my wall so I could plug in both my PC and 360. Having recently sold my 360, I decided to remove the switch for the time being. However, when I do that and plug the Ethernet cable from the wall straight into the PC, my internet becomes really slow! I don't understand it, surely if anything it should be quicker (not noticeably obviously)!?

The cable coming through the wall runs up through the roof and down into the ZyXEL Prestige 660-H in the lounge.

I've tried rebooting the router, the PC, repairing the LAN connection etc. Nothing seems to make any difference. Can anyone shed any light on this, it's really annoying! :(
 
Is it possible you've damaged the cable (loosened the jack plug) in any way while unplugging? Is the cable resting against any source of EM interference - lamp/light, power socket, extension strip etc?

It sounds coincidental and as you allude, your performance should not be negatively affected, all things being equal.
 
What is the lengh of the cable from your "ZyXEL Prestige 660-H in the lounge" to your PC? Along with switching frames, a switch will repeat a signal and make it stronger.
 
No the cable isn't damaged, but that's an interesting point by Gaz about the length of the cable. It's a 30 metre cable, which I didn't think was that long but a guy at work has just said he thinks the signal would start to deteriorate somewhere around that length. Is this true? Strange thing is it was working fine before I got the switch in the first place.
 
that length should be fine, it can run for up to 100Mish. What happens when you plug the switch in again? Have you tested the cable for any faults? (not terminated correctly?) what ping are you getting to the router?
 
When I plug the switch in the speed picks up straight away, at least it did last time. Am at work now so will try again tonight, will check ping to router as well.

How would I go about testing the cable, do I need a device for that?

Thanks for all your help.
 
You need a cable tester, you can pick one up fairly cheap(auction). Also making sure your network cable isnt running to near any power cables or anything which would give of a large EMI.
 
Tried the net when I got in and it was fine. Then I loaded Call of Duty 2 and tried to refresh servers, as that's what I was doing last night. Game just sits there, eventually shows up 1 or 2 servers, despite saying it's refreshing over 6000. Came back out and tried the net -> nothing. Could this be an underlying problem with Call of Duty 2? Although it still doesn't explain why I had instant slow internet when I originally removed the switch?

Pinging the router I get <1ms. Didn't have time to go and pick up a cable tester unfortunately.

Think i might try and CoD2 re-install. :(
 
so was that <1 when the switch was back in?

your router is probably blocking the servers list from being updated on CoD2, you need to open the nesessary ports for it to work properly or remove the router and connect directly to the modem.
 
Yeah that was with the switch back in.

Not sure about the port blockage, never been an issue before, and after the re-install last night it was back to finding large amounts of servers quickly. But still had some intermittent internet issues after refreshing the list :(
 
hmmm certainly doesnt sound like a problem with your internet or the connection from your pc to your router, possibly a flaw in CoD which is soaking up all your bandwidth perhaps. But i dno lol
 
I'd have said that CoD getting a server list was what was screwing up the router, through opening too many connections and overloading the router's NAT table, but if it works with the switch in the way it's unlikely to be that :confused:
Only other thing I can think of is the port speed negotiation - what does your network card say it's connected at?
