Hi Jackie, Thing is their speedtest site is www.speedtest.net It's Flash and I cant' seem to the "Begin Test" button with latest versions of JFW/WE. I can test it ont eh IPhone app no problems, export it to CSV and email it to myself. That keeps WIFI in the mix though and I want to test from Wired LAN only. Crazyness. I used to use Dan Earls Speedtest I think it was called. It doesnt' want to install on Win 7 though. On the cabling front... I've just ordered a couple of gold plated 4M RJ45 CAT5's's to be on the safe side. Cant' do any harm even if it doesn't fix it as at least one of them up there is 4 years old. Cheers, Barry.

Barry, oft times they'll listen if u go to their speed test site & report abysmal results. However, do check cables--I had that happen to me about a year ago wherein my modem cable was flakey & I was lookin for another ISP till I found the problem.
Hi Scott,
That's fantastic! That's exactly what I was looking for, real solid practical stuff there. Thanks loads. I might just get to keep some sanity after all! Good man!
Cheers, Barry.

Reading what you've put here I'm sure it's your provider but here's what you do.
Execute a ping directly from the router to the next hop gateway on
providers network. Use traceroute to figure this out and or the gateway statement in your router that you entered or was updated by dhcp.
Send like 1000 pings of a standard size, you should get 0 (zero) loss. Ping times shold range between 1 and 20 MS and no higher assuming a multi megabit connection. If you get loss on this segment you can tell your provider that you're losing packets between your head end device and their network. As for the WiFi, under normal conditions you should never see that much loss. You might be to close so back up across the room but honestly there should be no loss. To test this ping from your end device to
lan interface on your router (the gateway shown on the dhcp entry for your laptop) and see if you get loss. If no loss you know that segment is clean. If you got the same problem using a wire though I'm certain it's your modem / cable connection. Signal might not be strong enough and the modem can't get a link, cables degrade so this is worth checking.
As far as tools, NTR is good. It's trace route with more output.
Hope that helps.

Hi all,
I've been pulling my hair out for the past week and a half. Suddenly our bandwidth dropped off. I'm on a 20MB connection and normally get 1.5 to 2.4MB/s download from fast servers like the BBC and Sendspace.com where I have a premium membership. I began to notice speeds of 93K, 21K, and on one freaky moment 4Bytes! After 6 phone calls to the lovely outsourced call centre. During which, I explained the drastic reduction in speed. Coupled with the fact
i had
noticed I was losing packets. One 1st line Agent was able to see when he pinged my cable modem this was indeed happening. That it wasn't my hardware or the 6 computers I had at home. That I did know a tiny bit about computers and had confirmed that not only there was no hijackers on my WIFI, but that it didnt' make a difference whither I had my Netgear Router in the mix or was directly connected to the modem. Then after my ISP botched and ordered me two replacement modems
speeds
flew back up to normal and life went on. Today i noticed during mudding lag had started again. I also noticed using Ventrilo I was getting insane ping rates. In the thousands.
I started some ping tests again. pinging on wifi, 36 pings, 28 recieved. min - 22ms, max 480ms, avg 46ms Is this normal and should I expect a loss of packets on WIFI when i'm getting full signal, (as I was sitting beside the router, have all my WIFI gear bar the IPhone as N Adaptors). I did lose approx 1 packet out of the standard 4 packet Windows
test
when connected to the Router wired, and the modem wired, this afternoon. I'm trying to figure out how to establish what is the problem and minimise my own expense in the process. I can take a hit on time but I dont' want to go out and buy a new router just to test. Should I buy all new Ethernet cables? Demand my ISP send an Engineer out to check the cable box, and pay the £30 fee if all's fine? Is there any decent networking troubleshooting tools you all recommend? At first I thought was because I was messing around with creating my own 2K8R2 server networking at home, then i realised it wasn't just
Server
and the one laptop who was using it as it's Domain and DNS that were having problems. Web Pages were/are loading slowly. I've ruled out viral and malware infaltrations. I know no WIFI encryption is full proof but I'm using WPA2, TKIP, ASE, MAC Address Filtering, hiding the SID, checked the client tables on

I'm at a loss as what more to do and don't want to go back to the ISP without as much concrete evidence as possible. BTW. I know they do throttle but this is for peer to peer s'fers between set hours. They say streaming, and browsing will not be effected. It's Virgin Media in the UK.
Cheers as this is driving me mental!
