Broadband Packets being lost

  lindy 14:37 27 Dec 03

Please help - anyone?

I have wireless broadband using Netgear nd I'm on contract with my ISP for the next year and BT provides the Broadband line - Problem - the broadband is slower than the dial up and it keeps disconnecting.

The security log says that I'm losing packets - happening all the time.

Netgear say their equipment is working correctly as do my ISP and BT says the ADSL line is working correctly.

I don't even know what packets are - is it my settings are wrong or who is to blame - please help?

Is there good reception between the base and wire?

Signal strenght?

Are you using encryption for the wireless link?

Packets - A group of data sent at once instead of all the bytes being sent individually.

You could try this

Build a Bigger Buffer

Any modem user has probably received an important transmission with characters
missing. There is no way to find and retrieve the lost characters, but you can
increase your odds of receiving data intact by adding a line or two to your
SYSTEM.INI file. Before starting, it's important to understand how Windows
handles incoming data transmissions. Your modem sends the data it receives to
Windows' COMM driver. This stores the received data in a memory buffer until
your communications program retrieves it. Unfortunately displaying and storing
all the received data keeps your communications program working overtime. As a
result, it can't always retrieve data from the COMM driver as often as it
needs to.
By default, Windows sets aside just enough buffer space to store 128 incoming
characters. Unfortunately, once a modem has been connected, data flows
continuously. Your computer can temporarily stop the flow of data, but doing
that takes time. Meanwhile, data continues to arrive and must be stored in the
COMM driver buffer. If your communication link is slow, or your communication
program is fast, a 128-character buffer might suffice. But with a fast modem
or a slow program, it's possible for more than 128 characters to arrive before
your program can process them. In that case, the COMM driver has no place to
store the 129th character and those that come after it.
Luckily, you can expand Windows' COMM buffers. By adding a line to the
[386enh] section of the SYSTEM.INI file, you can create a buffer as large as
10,000 characters. Actually since the COMM driver maintains a buffer for each
of your PC's COM ports, you can add up to four lines, each controlling the
size of a particular port's buffer. Each line should resemble this:
Replace the x with a number between 1 and 4 to indicate the desired COM port,
and substitute num with a number from 128 to 10,000 to set the buffer size.
You have to exit and restart Windows for the change to take effect. Use a text
editor when editing SYSTEM.INI.
As for how big should your COMM buffer be, if characters are being dropped
from incoming data transmissions, create a new buffer of at least 2,048
(2KB) characters. If problems persist, increase the size of the buffer to
4,096 (4KB) or even 8,192 (8KB).

Thanks that page you've suggested is really helpful. Hope I can figure it all out - if you have details it suggests pinging to another address - should I just use the general address of or should I be doing something else - I really am a novice.

My link with the wireless router is good and I can see the other computers on the network ok - it's just the internet connectio that's not working.

Any other help would also be appreciated.

to find out the IP address open a command prompt and type "ipconfig /all". look for the section on the wireless connection and then for the IP address.

Thanks for the info - only problem is - how do I open a command prompt?

Assuming Windows XP

Start, Run, Type in


and click OK

I've tried your suggestions for changing the Comm buffers however it didn't appear to work. Maybe I've got it wrong as I'm on wireless and I changed com3 which is where the modem is attached. I have a suspicion that is wrong. In fact I don't know which com port wireless would use. Any suggestions.

Help appreciated

Your hyperlink was a great help, however it all relates to network using cable and I'm wireless. I don't know if that makes the difference, but if there are any other hyperlinks you can find, it would also be appreciated. I have tried what was suggested.

Any other help also appreciated.

If you can connect you are on the right Com port
