Internet running slow

Linton

My internet connection has been running slowly for some days. Malwarebytes picked up nothing of interest. The event log on my router is showing a lot of port forwarding messages: For example....

Any relevance?
Any ideas?
Thanks

Russian? Looks like a UK DSL line - http://whatismyipaddress.com/ip/62.56.49.34
It looks like 2 machines on your local network have been contacted from that IP. I'd look at your firewall setting to see why those connections were not blocked. Possibly UPnP active?

There looks to be some sort of hack attempt from the USA which was blocked.

The rate these things were logged at would have no effect on your speed.

Have you been running any sort of P2P software or video streaming etc. (which may use P2P).

Who's you ISP? I've been having problems with BT's dns servers this week (not that they'll admit there anything wrong). I just reconfigured to use google's dns and everything is zipping along now.

About the firrwall log - those odd port numbers look like something a bit torrent application would use. I don't think that's your problem though.

Hi

I assume the first is your ISP. As to why the others I don't know, but a firewall block would be recommended.

Unlikely to be your issue.

Do a bandwidth test to find out your real speed and stop turning off your router/modem (if you do).

If you've not changed or installed anything, then its unlikely to be a problem at your end.

When the internet connection is working I get a speedtest result close to my line speed. When it isnt the browser hangs waiting to connect to the speedtest website or any other website.

Currently I am seeing about 5 connections a minute, rather more than on the report in my first post.

I have switched as suggested to the google name servers. This may have helped somewhat, its difficult to be sure.

I dont run P2P software or anything unusual. When the system is slow, the % network utilisation on task manager is nearly zero.
