Hello. For the last week i've noticed my internet connection dropping / being slow. I did a speed test and instead of 200mb that im suppose to get.. i get 9.

I've contacted my isp (virgin media) and they said theres no faults on the line but are sending someone out in 3 days to check my home out.

Its slowly getting worse. If i download something i have to cap it to 500kbs otherwise my internet will die and i will need to restart the computer (not router) to get the internet back on.

Last night i was downloading and streaming but i kept blue screening...

Any ideas? I've tried to update my network drivers and it seems fine.
I've tested my speed on my mobile over wifi and im hitting 130mb. Its just the computer thats having problems.

Whenever the internet dies, i have to reboot the computer. So as i dont have to reboot the router.. i guess thats not the problem?
Virgin tech are coming in a few days so maybe they can help.. but thought i'd try on here also!

One thing to mention.. i have played about with safeip (vpn) but now its deleted so not sure if thats changed any settings.

Any help would be greatly appreciated!!
 
If everything works fine that isn't your PC then just cancel the Virgin tech, there's no point in them coming out and you waiting in for them.
 
have you got another laptop or pc in the house? you coud try iperf from one device to another to check if its you pc. also try another port on the the virgin hub?

factory reset the router incase theres some issue on the port
 
NIC driver problems i would say. AS for the speeds try a sustained transfer, dont use those speedtest sites, they are useless. I did mine and it was 11mbit. I am downloading a file right now at 186mbit.
 
How are you connecting to the router? List all network devices, have you tried other cables?

Was it ok before you tried this VPN ?

As above, cancel Virgin callout.
 
Hello again. I unplugged my Ethernet cable from the computer and plugged it back in. Boom 200mb... internet is fine. downloads are fine.
After 2-3hours my connection drops and reconnects.. back to 9mb. Is the Lan card on the way out you think?
 
Very unlikely that it's the LAN port 'failing'. They tend to work, or not.

Any windows events recorded when the connection drops?

Can you answer the question bledd asked you about the VPN? Does the timing suggest that it is a likely cause?

Do you have system restore points or backups you can use?
 
Sorry. It seemed to work fine before i played with a vpn but i can't be 100% sure.
Nothing in event viewer. I'm going to replace the cable today. its probably 10years+ old
 
Firstly you'll need to know which Virgin Hub you have as some of the later ones that were supplied have Intel Puma 6 chipsets which has a bug which causes latency spikes and packet loss. A firmware update is on its way but I'm not sure if its been issued or not and its entirely reliant upon Intel fixing not Virgin. Info

Secondly you'll need to be aware that the Virgin network is widely over subscribed causing exactly the issues you speak of during peak times, have you done a speed test outside of peak time between the hours of 2am and 3pm? Does it increase substantially? If it does the chances are over utilisation is tanking the connection quality.

I suggest setting up a quality monitor over at Think Broadband, its an unattended tool that does not need your machine on and gives possible pointers as to when the quality of service is dropping.

As an example this is my Virgin line below, you can see at peak hours (evening) it's basically unusable because of latency issues affecting the quality of the connection, my speed also goes from 200mb at 12pm to 1mb at 8pm. Virgin customer services will not immediately acknowledge over saturation and will happily offer tech visits to fix issues that a technician can do absolutely nothing about which wastes time, adds in cost for Virgin but gives the customer a nice warm fuzzy feeling of action being taken.

Armed with 2 weeks worth of daily speed tests inside and outside of peak times along with a daily capture of the think broadband monitor, I got Virgin to release me from my contract 15 months early with no penalty charge and a full month refund and I've happily now re-enabled my phone line based fibre connection and much happier with its consistency.
 
A work friend reckons the network driver is calling for a file in system32 which is no longer there so it's causing the bluescreens.
Bleed: I'm using a wire from computer to router. The problem started around the same time I used a vpn but not certain.
List all network devices?

I don't think it's a problem on virgins end. Once the connection drops and starts straight away that's when I'm dropped to 9mb and its when I will bluescreen / disconnect if I download too fast or download and stream at the same time.
Unplugging the wire from pc and re-plugging it back in fixes the problem straight away.
I'm going to pickup a new wire this afternoon.
