BT Broadband keeps disconnecting

BT Broadband..  ??  Could you expand on this..??

If it is ADSL, then you may want to ck your MTU settings..  Cable uses an MTU size of 1500, but DSL needs a little less since they add a packet header..  1492 is what you would need for this..

Here is a little more explanation, and how to:  (Copied from a previous post..)

ADSL Packet Loss and MTU Size

Sounds suspiciously like packet loss.  This sometimes happens with a ADSL Router (especially if you are using PPPoE).  Your system is probably set for an MTU size of 1500, whereas it might need to be set to 1492.  

This is the fix for WXP.  But it should also work in W2K.  Let me know.

Modify the MTU Size
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To modify the PPPoE MTU size, locate the following registry key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Ndiswan\Parameters\Protocols\0

and add the following registry values:
Value name: ProtocolType
Data Type: REG_DWORD
Value Data: 0x00000800

Value name: PPPProtocolType
Data Type: REG_DWORD
Value Data: 0x00000021

Value name: ProtocolMTU
Data Type: REG_DWORD
Value Data: the appropriate MTU size (in decimal)

To do so:
Click Start, click Run, type regedit, and then click OK.
Locate and then click the following key in the registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Ndiswan\Parameters

On the Edit menu, point to New, and then click Key.
Type Protocols, and then press ENTER.
On the Edit menu, point to New, and then click Key.
Type 0, and then press ENTER.
On the Edit menu, point to New, and then click DWORD Value.
Type ProtocolType, and then press ENTER.
On the Edit menu, click Modify.
Type 800, and then click OK.
On the Edit menu, point to New, and then click DWORD Value.
Type PPPProtocolType, and then press ENTER.
On the Edit menu, click Modify.
Type 21, and then click OK.
On the Edit menu, point to New, and then click DWORD Value.
Type ProtocolMTU, and then press ENTER.
On the Edit menu, click Modify.
Type the appropriate MTU size (decimal value), and then click OK.
Quit Registry Editor.
Notes
As a result, if the MTU size is set to 1460 (decimal), the max value of NUM in the following command line can be 1432:
ping IP_address -f -l NUM

You may need to restart the computer to make the change take effect.

If none of the above work, check interference.

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

Hey Pat..  Nice list..!!

FE

ok, will take a look and get back to yous

Fatal Exception:

Thanks, but not my list. It's straight from Microsoft's private database for broadband and MSN tech support. <smile>

pat

private database, eh..??  figures...  hehe

Only as long as I continue to work for MSN. Then, it's gone. <smile>

pat

Ahh..  as long as we know it is there, we can get to it eh..??   <just kidding..!!>

Can't get to it; however, if you have a question pertaining to MSN broadband, MSN software, MSN messenger, .net passport - some on IE and Hotmail, I can look it up. <smile>

pat

Thank u Pat..!

I've copied enough of your answers, I probably owe you a few lookups!
