Broadband speed issue

(1/2) > >>

Rich J:
Hi All

We recently had a Virgin Media broadband outage that lasted approx 36hrs - a local issue, not at our property. That has now been fixed but I find that my internet speed is very slow, compared to that before the outage.

I've twice contacted Virgin 150 (20mins waiting, 10mins with operator, then had the call cut off both times before the issue was dealt with!!) I've gone through all their instructions ie: speedtesting, re-booting, factory re-set etc. to no avail. 

My package gave me a stable 20Mbps download speed and about 2.7 upload speed and that is what I've had for about 2 years with no problems.  After the outage, I'm getting 2.27Mbps download and 1.97 upload.  Ping is @ 300 ms.  This is causing major issues with system updates, especially if there are larger files involved.  Before, the updates would download between 10 and 20 seconds, now it can be anything up to 20mins!

My rig has a wired ethernet connection (through D-Link homeplugs) and pinging my router returns -


--- Code: ---
[email protected]:~$ ping 192.168.0.1 -c 5
PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data.

--- End code ---

which suggests the internal wiring 'tween rig and router is ok.

From the computer, Speedtest.net to Virgin's server in Manchester returns Ping 10ms,  Download 2.89Mbps,  Upload 2.00Mbps
Yet from my smartphone, Speedtest returns (wirelessly)  Ping 24ms,  Download 21.01Mbps,  Upload 2.48mbps from the same server......!! 

I'd expect the ping to be slower as it's wireless but the other figures suggest that the internet speed is ok and the issue is with my computer.  I'm baffled, to be honest!

Any help would be good and thanks in advance.

what's the output from

--- Code: ---
ifconfig
--- End code ---

and I take it you've tried rebooting both the PC and router ?
(have you tried turning it off and on again ;D)

Hi Mark!  Yes to both - several times!  About the only thing I haven't done that's just occurred to me, is deleting the ethernet connection and re-setting it.  Do you think that's worth a try?

info as requested -

Basically, I'm trying to find out where the fault (if any) lies, before I set off on a rant at Virgin!  I must say I'm becoming a bit disappointed with VM, from having years of near flawless service there seems to be a different culture at work.  Probably cost-cutting like many other companies, but that's a different issue....  Sign of the times  ::)

Rich J:
I left things to settle over the weekend and have just checked my stats on both computer (wired) and Smartphone (wireless) to the same server.

Computer - Ping: 9ms,  Down:  3.00Mbps,  Up:  2.00Mbps

Phone -      Ping: 24ms,  Down: 19.19Mbps,  Up:  2.39Mbps

Which does suggest there's an issue at my end? 

Either with the Homeplugs connectivity (quite possible, but the ping figure is a puzzle) or my network settings/driver are wrong or have become skewed in some way, maybe through a recent update? 

How do I test please, if the network set up is working properly and that I do have the correct driver?

TIA

Rich

Update:  I've taken the Homeplugs out of the equation by moving the router back to the office and wired directly to the computer.  Test is as follows -

Ping:  8ms,    Download:  4.06Mbps,   Upload:  1.99Mbps

So no improvement, which rules out the Homeplugs as the problem.  So, it's either my config and/or network driver that's at fault, the hub itself is playing up, or Virgin have me 'throttled' for some reason.   I've messaged Virgin Technical to get them to look into the hub but would still like to check my set-up, if poss, in the meantime.
