Ok, riddle me this!
Last saturday my Virmin Media broadband connection went screwey. So did a lot of other VM users around the country.
However, my area was reported as being fine since tuesday.
But, when i do a continuous ping on a VM dns server, i'm getting responses of between 500ms 3000ms, instead of the expected 6-20ms.
It will often timeout for a few attempts then report high timings again with the odd 20ms or so every maybe 20 tries. Completely random, but 95% is around 1sec, totally unnaceptable.
My network is:
VM cable modem, plugged into Netgear WNR2000 router (1 month old), plugged into 3com gigabit 24-port switch. All client pc's and WHS are also plugged into the switch. A fairly standard ethernet network really.
So, i decide to plug my lappy directly into the modem via crossover cable. Pings were coming back between 5-20ms....great! So the problem points to my router.
So, i swap out the WNR200 for my older Netgear FVL router, rebooted modem, rebooted router. Router got an ip, but again pings were high, same as before.
So, i'm thinking, surely BOTH routers can't be faulty here.
EVentually got through to VM who tested my modem as working fine and they could also see that it had connected with a different mac address (the change of router), but it reported no errors at there end and there was 0% packet loss. So i have to accept that its an issue my end, but they are sending out a new Ambit 256 modem anyway, currently i have the 250 model.
So, i decide to change the cable from modem to router = no difference in ping.
So i then plug my WHS (which i'm now using to run tests on) straight into the router thus bypassing the 3com switch = no difference in ping (still high).
I'm now at a loss. I refuse to beleive both (or even one) of the routers to be faulty.
I've changed the cable and i've bypassed the switch. I did this because when i kept swapping out the routers they weren't connecting to the network unless i rebooted the switch, which i found odd as that shouldn't be an issue. Its not a managed switch, but i use these at work too and they should just work without any rebooting etc etc. just because you plug something into it.
I feel i've elimated most things now, even other client pc's and their cables as bypassing the switch and going straight into the router effectively tests that theory too.
Kids need the internet for homework and school login. Mrs needs it for her uni degree......and i for COD:WAW
Can anyone offer any advice on this please, as its driving me nuts. I'll register the new modem when it comes, but i just can't how that may make a difference, its handing out an ip to the router, the same way it does when a pc connects to it.
Thanks for any advice offered.
