Internet connection cutting out on W2k

Hi lz7cjc,

Do you have another ADSL modem you can borrow and test with that?

Cheers,
IceRaven

unfortunately not - have tried changing the filter
any tests I can do on the actual modem to find out if there is aproblem with it?
thanks

Sorry don't know of any.  Maybe some other experts will.

Good Luck

IceRaven.

This is a long list, but is SOP for troubleshooting these types of problems..

DSL/Broadband Interference Troubleshooting

The dsl modems usually run at 900 mhz and are affected by other frequency devices. The following should be checked for by removing the possible interference all at once, running the dsl modem connection, and then begin adding items back on - one at a time.

MSNBB: How to Check for Interfering Line Devices(non-public database)

SUMMARY
This article describes how to check for and reduce interference on DSL lines. DSL operates by sharing the existing telephone line copper wiring with the telephone service. In this shared environment, any device using the telephone line has the potential to interfere with the DSL connection. The most common interfering devices are:  
 
-  Telephones: cordless phones that are 2.4/5 ghz can be on the same phone line but not on the same phone/dsl cable as the modem; 900 mhz cordless phones should not be in the same room, sometimes not used at all (dsl modems run at 900 mhz); all phones need to be filtered
-  Answering machines - should be filtered and not on the same cable as the modem
-  Separate Caller ID boxes - should be filtered and not on the same cable as the modem
-  Fax machines - should be filtered and not on the same cable as the modem
-  Dial-up modems - when using for faxing, etc., remove the dsl/phone cable from the modem; the dial up modem can hang up the dsl modem
-  Alarm systems - must be filtered before being attached to the phone line (alarm company is responsible)
-  Digital Cable and TV programming systems, such as TiVO; must be filtered before plugging into the phone line OR just leave unplugged when not using - dsl modem dsl/phone cable unplugged when using systems
-  Digital water or gas meters that transmit data over the phone line - must be filtered
-  Surge suppressors connected to the telephone cable - remove if it cannot be filtered
-  Unfiltered splitters - filter them
 
MSNBBTS: How to Check for Interfering External Devices(non-public database)

SUMMARY
This article describes how to check for and reduce external interference on DSL lines. External interference is caused by devices that generate frequencies used by the DSL line. DSL operates over a series of channels similar to AM/FM radio signals. These channels run between 4 kHz and 1.1 MHz. Any device that emits a frequency in this DSL range can cause interference. The most common interfering devices include:   Cordless phones
 
-  Sprinkler systems - inside (filter if connected to phone line); outside (if phone lines are above ground, no problem; if buried, have phone company mark where they are buried and turn sprinkler system on to determine if it's flooding over the area where the wires are buried)
-  Radio, TV or cell phone towers within a 1 1/2 mile radius - nothing you can do here, except go back to your cable, which is unaffected for frequency
-  Halogen lamps - remove from same room as modem
-  AM radios - remove from same room as modem
-  Twisted cables (where phone cables from the modem are twisted with other wires such as power cables, printer cables, or powered cabling) - leave hanging free
-  Cable additions - use only the cables provided with the dsl modem; for MSN provided modems the length is 6 feet; adding connectors, extra cable, splitters, etc. can actually disconnect you
-  Ham radio operators - nothing you can do about this either
-  Other radio frequency devices

thanks - the only possible one that could have been effecting this is a cordless phone - however this has been plugged into the same filter as the modem for the last year without any ill effects. Indeed i unplugged it anyway but the problem still occurs

thanks

I have searched the registry and I have no entry for
System Key: [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\
Interfaces\[Adapter ID]]
Value Name: MTU
Data Type: REG_DWORD (DWORD Value)
Value Data: Default = 0xffffffff

have not added to the registry before manually - do I need to add this? how would I do this?
thanks

Yes, you can add this to your registry...   But..  be sure to backup your registry first..!!  This can be done via ntbackup, backing up your System State...  or..  navigate to the key you are wanting to modify. Once there, right click the key in question, choose Export. Name it according to the edit you are going to perform ending with (ex) xxx_backup.reg.

Then..  perform the operation to create a New MTU value...

Once you locate your adapter, just right click on the Adapter ID and then New > Dword Value..  Then on the right hand screen, right click the new entry and Modify it to your new value...

Question you asked from before,
"is the 1492 a decimal or hexidecimal value"

the answer is DECIMAL

the both represent the same thing

5d4 is the same representation in HEXIDECIMAL

Hope that helps,

Hows this going !

hmmm

:)

hi
sorry I am currently on holiday so will pick it up on my return
