D-Link → Sudden surge in speed cause me to d/c. - DGL-4300

I am using DGL-4300 and I notice that when I do download a file at very high speed, i.e. 900kb/s - 1.1mb/s, my whole connection will kind of die off. Not as in totally d/c. DURING the downloading period,

But my MSN will go offline;
I cannot surf the net;
My games that is connected will get d/c;

Only AFTER the downloading is completed then everything is normal again.

One such example was when I was downloading this:
»www.sonyericsson.com/dow ··· 0.21.exe

Any reason or remedy to this?

Maybe provide us with a little bit more information?

Are you using Cable or DSL?

What modem? ...

Firmware 1.8 on your dgl-4300?

Greetings, Jellen

Oh.

I'm using CABLE on: Motorola SurfBoard 5100 Cable Modem.

Firmware yes, 1.8

Did you try what I suggested on Neowin?

Btw, were you using Vista or XP?

after looking at his older Post he/she is using Vista

TRY this TCPIP patch

Ken, I replied to you on Neowin.

Is it necessary to increase my TCP/IP half-open limit on Vista?

No. But Vista's receive window auto-tuning isn't compatible with some adapters (and some NIC drivers), and the one of the common side effects of that is MSN disconnects and/or NIC unresponsiveness.

To disable it, type the following command at the command prompt and press enter:

netsh interface tcp set global autotuninglevel=disabled

Reboot. If that doesn't make any difference, then set it back to the default:

netsh interface tcp set global autotuninglevel=normal

yes cause there is only 10 open

That's a common misconception. There is no 10 incoming connections limit in XP or Vista. There is no limit on the total number of incoming or outgoing connections in XP or Vista.

The limit is on the number of half-open TCP connections per second waiting for a reply.

There is also a limit on concurrent Samba connections, but that is separate issue.

YES on XP SP2 and VISTA

EventID 4226: TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts.

Yes I do get that event error too.

Anyway Ken, I will communicate with you from NeoWin forum thread itself.

maybe that could be why

Strange I done that patch and I tried the same download for 3 times and I NEVER got d/c. ermmm

What patch? The connections attempt patch?

Half-open TCP/IP patch.
