Slow ISDN connection

[Pilot Pete]

Guys. .. .Sure it's been done before but could not find(read understand into that!) the right answer using the search facility.. .. .We 'upgraded' (supposedly!) to ISDN, using BT Home Highway some months back. I was suprised to see no noticeable speed increase for loading of internet pages etc etc. . .. .We have BT Surftime (evenings and weekends) and an internal ISDN modem, Windows 98, McAfee virus checker and firewall (which someone told me will seriously slow things down).. .. .I was also told that I could connect the modem to use two of the available telephone lines which would speed things up. Any idea if this is correct and if so, how do I do it? (there is only one 'outlet' socket on the modem card.). .. .What I am asking for help with is an idiots guide to what I should check to ensure we are 'optimising' what we have installed. I am not a techie, so keep it simple guys!. .. .Thanks in advance. .. .Mr & Mrs PP. . . . <small>[ 16 March 2002, 08:12: Message edited by: Pilot Pete ]</small>

I use ISDN but in France so I do not know about BT Highway. I assume that all the setups are the same so if a UK user does not come up with an answer for you give me an email and I'll explain.

To go back to your original question provided that your ISP supports 128 rather than just 64 in dial-up-network right click on your connection (I assume BT Highway) and on the panel that appears click on Multilink/use additional devices/add. This should show you both your ISDN lines, click on the one that is not the one that you are already using then OK. This should then tie both your lines together and subject to your ISP give you 128. My ISP doubles the actual connection time when I use 128 and charges that way.. .. .Bon chance.

Hi !. .. .Just a quick thought for you , windows TCP/IP settings, ie your MTU value and RWIN settings as default are not optimized for DSL, CABLE or DIAL UP but instead give the overall best performance for a wide range of connections, it is absolutely necessary to TWEAK these values for a particular connection type, you can expect to see a 10 to 50 percent increase in upload and download speeds once these settings are adjusted.. .I KNOW I KNOW ! Adjusting these settings requires you edit some registry values and if you're like me you shy away from manually twidling with anything has to do with the windows operating system as though it were Hexed, which it is !. .FORTUNATELY, there are a multitude of programsout there that will TWEAK and return these settings to DEFAULT if not satisfied. The best program I have found, a free evaluation is available for download at :. .<a href="http://www.tweakmaster.com/" target="_blank">http://www.tweakmaster.com/</a>. .I use it myself and have seen a 25 percent increase in throughput and 10 percent increase in stability, I however have a cable modem and available bandwidth continuouly fluctuates with demand, I expect you will see a noticeable improvement.. .My suggestion to you would be to download the program, its easy to use and menu driven, try one of the threeoptimization schedules provided and test the performance of your unimproved connection against each one of the 3 tweaks above, a really good internet connection test is available at :. .<a href="http://www.pcpitstop.com" target="_blank">www.pcpitstop.com</a> . .just select internet connection in the top left of the menu and you will be able to test everything from ping time to upload and download speeds, in addition it will run a health check on your entire PC if you so choose, FOR FREEEEEE !!!. .I ask you can it get better than this ???. .. .If none of the above work , then by all means change your ISP.. .. .For reference MTU=Max Transmission Unit. . Rwin=Receive window. .. .A careful balance of these is required to boost your throughput withought packet loss that is why there are 3 optimization schedules in Tweakmaster.. .REMEMBER ! You can alway restore your defaults and it aint gonna cost you a dime or over 30 mins of your time to try the above. Drop me a line at [email protected] If you have any other questions or if you didn't get an increase.. .. .Sincerely:. .. .Marc
