Nitro4WD Posted January 28, 2005 CID Share Posted January 28, 2005 Hi everybody! I posted a couple of days ago regarding my ridiculously slow 512(!)kb/s virgin connection, which was running at less than half supposed speed. Some great advice and cablenut help from VanBuren (thanks for that!) cured the problem, but it happened again on the very next startup. I've now come to my wits end trying to fix it. Cablenut and DR TCP have been used with various configurations (following carefully the advice and guidelines from this site and dslreports.com), as well as many tweaks from dslreports. I've tried four different firewalls, limited and eventually stopped all non essential programs and tools from using the connection, re-booted again and again and again. I managed, after a cablenut settings .zip Vanburen passed on to me, managed to get 505Kb/s down, but as I said it was rather short lived. I've checked for spyware/adware and viruses (using adaware, spybot s+d, Norton antivirus and AVG antivirus). My system is a Compaq P4 2.6GHz, 256MB RAM, 60GB HDD (around half full). I am at the moment running the Kerio firewall (wanted Sygate but it kept crashing Windows). Could I have a registry problem or something similar? I don't think it should be my ISP, as their connection ratings seem high and no one I know using them has ever complained. I emailed virgin themselves a whole bunch of times, but for some reason they haven't mailed back...hmm. Anyone willing to help would have my deepest gratitude, 'cause I am about to go severly nuts. test and tweak results: :::..

MrConstantin Posted January 28, 2005 CID Share Posted January 28, 2005 Hopefully someone is able to help! I remember thinking my connection was running slow, so I complained to my ISP when it was running at 2500 Kbs for downloading and 250 for uploading. But since then I've doubled my connection speed, thanks to the Tweaking information I found on this site. Hope the same can be done for you...Eventually.

Velocity Posted January 28, 2005 CID Share Posted January 28, 2005 I dont know if this would have a whole lot to do with your connection loss but your 2nd hop in your trace route is alittle high. 2 19 ms 58 ms 105 ms brhm-t2core-b-ge-wan71.inet.ntl.com [213.106.231.185] Ping that router and see what kind of connection your getting..It looks like its gonna have alot of fluctuation in it. If it does call your isp and tell them which hop and the ip you are getting high ping times on. Quote Link to comment Share on other sites More sharing options...
VanBuren Posted January 28, 2005 CID Share Posted January 28, 2005 hey again Nitro4WD somehow you must have restored the resistry or windows did, thats why you noticed the canges only after reboot. i agree with Velocity, that second hop seems unstable and you should check it time to time. i thought ntl was a cable isp, correct me if im wrong anyways try this file, unzip it to C:ProgramCablenut then open cablenut adjuster, click delete cablenut tweaks + save to registry now go to top left corner, click file, click load custom settings, browse to C:ProgramCablenut and dubbleclick onthe file you unzipped. now click save to registry again and reboot, also reboot your modem and router for 30 seconds good luck VanBuren Quote Link to comment Share on other sites More sharing options...
Nitro4WD Posted January 28, 2005 Author CID Share Posted January 28, 2005 Hey there! Thanks for the responses! Can't get over how good a community this forum generates. Thanks for the cablenut tweaks VanBuren, I did everything you said, but unfortunately it doesn't seem to have worked: :::..

I'm a noob to tweaking as you can tell, my last 2 high speed accounts were both from a network and managed by others. Now I use a normal adsl modem running through the filter that came with it. I've been pinging that abnormally long hop too, it's averaging out around 150m/s, which as you noted is rather a long time...could it be something on my isp's end? Really appreciate any help! Peace.

VanBuren Posted January 28, 2005 CID Share Posted January 28, 2005 hey again Nitro yea it is a problem at your ISP end if you average that node with 150 ms run this test and let me see what settings you have now after you loaded the file http://www.dslreports.com/tweaks post result URL VanBuren Quote Link to comment Share on other sites More sharing options...

Here's my tweak results after the cublenut tweak: http://ttester.broadbandreports.com/tweak/block:5a02807?service=dsl&speed=512&os=winXP&via=normal If my ISP is at fault is there anything specific I can berate them about? lol Thanks!

VanBuren Posted January 28, 2005 CID Share Posted January 28, 2005 you retransmit packets, and that probl beqause of that node, it might be overloaded, ISP hook up too many users on same node however run this test aswell http://nitro.ucsc.edu/ copy all text you find on result, click more info and copy all text paste it in a new post VanBuren Quote Link to comment Share on other sites More sharing options...
