karthic Posted February 18, 2006 Author CID Share Posted February 18, 2006 thank u fallow earth for ur reply yes i get fluctuations in my speed but to wild limit i.e., instead of 256kpbs(rated) iat times get only 95kpbs Moreover the transfer rate doesn t remain constant at all During heavy downloads it affects me very much drooping to just 12KPBS in dialup itself i had abt 4-5KPBS then wat s the point in having the broadband connection dude? Pls help me to finetune my speed so that i ve a somewhat CONSTANT SPEED &TRANSFER RATE during most of the times of the day!!!!!!!!!!!!! u see i just want to set it right ok dude ! as u told i carried out ht eone told by u & i ve no knowledge of identifying which all processes r hogging my speed so i m posting it for ur perusual hav a look at it & post ur comments pls TCPSVCS.exe SVCHOST.exe System SVCHOST.exe System IEXPLORE.exe SVCHOST.exe ALG.exe SVCHOST.exe SVCHOST.exe CCAPP.exe IEXPLORE.exe TCPSVCS.exe here are some processeswhich i think may help u many PID s in the cmd window dont show up in the task manager window & some some procces r repeated many times eg., SVCHOST.exe pls post comments Quote Link to comment https://testmy.net/ipb/topic/11291-query-reg-my-broadband-speed/page/2/#findComment-119477 Share on other sites More sharing options...
karthic Posted February 18, 2006 Author CID Share Posted February 18, 2006 hey dude i do know basics of duplex man but my q is relation betwn the alarm info & ur advice i.e., "See if you still get this alarm if you raise your modem one foot above your comp?" Can this prob be rectified by placing the modem as u said? or, r there any other alternatives??????????

trogers Posted February 18, 2006 CID Share Posted February 18, 2006 Before you relocate your modem, the duplex setting between your Nic and modem matches. After relocation, nitro test raised the alarm of a mismatch. My guess is that the switches in your modem are being affected by electromagnetic interference. This may also explain the wild swing in speeds. Since your comp table is cluttered with many items, you may want to place your modem on the floor directly below your computer tower. Cables from the wall runs along the floor to your modem and then a cable from your modem up to your comp tower. Later, you may be able to find a low support for your modem so that humidity will not affect it.

trogers Posted February 18, 2006 CID Share Posted February 18, 2006 See if this adjustment to your Nic will work. Windows 2000 or XP: to change to auto-sensing: * Open Control Panel. * Double-click Network and Dial-up Connections. * Identify the icon for your cable modem connection: usually Local Area Connection. * Right-click that icon and select Properties. * Under the ethernet adapter icon, click the button Configure. o Click the tab Advanced to bring it to the front: + In the Property box, the property name to be selected varies according to model of ethernet card. Examples are: Network Link Selection, Media Type, Connection Type, Duplex Mode, or any similarly-named property which can have Values looking like Auto-Negotiation, or 10BT, or 10BaseT. + In the Value box, select a value for auto sensing or something similar. o Click OK to exit the Adapter settings. * Click OK to exit the Connection properties.

trogers Posted February 18, 2006 CID Share Posted February 18, 2006 In this case try setting the Nic to 10 half duplex and test. Quote Link to comment https://testmy.net/ipb/topic/11291-query-reg-my-broadband-speed/page/2/#findComment-119514 Share on other sites More sharing options...
karthic Posted February 18, 2006 Author CID Share Posted February 18, 2006 do u mean 10Mbps/Half duplex?(it s like that there man) Quote Link to comment https://testmy.net/ipb/topic/11291-query-reg-my-broadband-speed/page/2/#findComment-119520 Share on other sites More sharing options...
trogers Posted February 18, 2006 CID Share Posted February 18, 2006 Yes. 10 for Mbps and half duplex Quote Link to comment https://testmy.net/ipb/topic/11291-query-reg-my-broadband-speed/page/2/#findComment-119528 Share on other sites More sharing options...
trogers Posted February 18, 2006 CID Share Posted February 18, 2006 This is for the case where you do not have a router. If you do have a router, try setting Nic and the WAN of the router to auto-sensing first. If this do not work, adjust the WAN to 10 Mbps/half duplex and leave the Nic at auto-sensing.

trogers Posted February 18, 2006 CID Share Posted February 18, 2006 I have to go to bed. It's past 2 am here. If 10 half duplex does not work, try 10 full duplex. And if that also cannot work, reset everything to auto-sensing and get your ISP to give you a new modem.

trogers Posted February 19, 2006 CID Share Posted February 19, 2006 Other possible cause is poor telephone line or loose line connection. CA3LE has posted some comments about this here: http://www.testmy.net/forum/index.php?topic=11976.msg119237#msg119237 If possible, do some visual inspection of your cable or phone line within your house to the junction box outside your house..

FallowEarth Posted February 20, 2006 CID Share Posted February 20, 2006 You can always try booting into safe mode w/ networking to see if the speeds fluctuate as much as the do in normal mode. If they do, you can pretty much guarantee its on your ISP's end. If they don't,then it's something(s) on your PC.
