SP2 speedtouch..cant access my router!

[mhtsaras]

I have Speedtouch 510 ethernet router and with WinXP SP1 it was working fine, telnet, web interface and UPnP conectivity and disconection.

For 2 days now after the instalation of SP2 the problems started.

When I power on the router I can configure it via telnet 10.0.0.138, open the web interface, or even

conect with UPnP "internet connection" but after a minute or two surfing on the internet, I cant access

the router or disconnect it.

When I try to open the web interface "http://10.0.0.138" it gives me a "The page cannot be displayed"

When I try to "telnet 10.0.0.138" it gives me a "Connecting To 10.0.0.138...Could not open connection to

the host, on port 23: Connect failed"

When I try to disconnect with the little UPnP "internet connection" icon on the bottom right taskbar it

gives me an error.

And when I try to open the Dr Speedtouch (my router's diagnostic tool) for diagnostics after I type the

password the router reboots.

After the reboot all the above are working but after a wile nothing works and I cant access the router.

I tryied 3 times to reboot and restore the factory defaults and reconfigured the router but the problem

remains the same.

I also have disabled the new windows xp sp2 firewall.

The funny thing is that even that I cant acces the router, I can surf on the internet, downloadeverything without a problemo.

Any suggestions?

Is it a Win xp SP2 UPnP or something bug?

New info....

While I cant access my router I noticed a connection with netstat :

C:\>netstat -n -o

Active Connections

Proto----Local Address----Foreign Address----State------PID

TCP----10.0.0.1:1897---- 10.0.0.138:80----SYN_SENT----1084

10.0.0.1 is my Network card

10.0.0.138 my routers address deafult for speedtouch modems

SYN_SENT state means :session has been requested by us; waiting for reply from remote endpoint

And also it's all the time there until I reboot the modem.

Now the process that is trying to do this connection based to the PID is with a "tasklist /svc":

svchost.exe 1084 AudioSrv, CryptSvc, Dhcp, dmserver, ERSvc,

-------------------EventSystem, FastUserSwitchingCompatibility,

-------------------helpsvc, Netman, Nla, Schedule, seclogon,

-------------------SENS, ShellHWDetection, srservice, Themes,

-------------------TrkWks, winmgmt

Wich runs all the services on the right.

Now what service is asking something from my router on port :80(http)and the router is'nt responding, it's like a denial of service thing from my router, but happens only after 1-2 minutes online?

I mean is there a way to find exactly which service is waiting to receive the return SYN+ACK packet?

[mhtsaras]

A minute after I connect to the internet those two dll's from svchost.exe are trying to make this connection that my router can't send or can't understand to reply with SYN+ACK packet....

C:\>netstat -n -b

Active Connections

Proto---Local Address---Foreign Address---State---PID

TCP---10.0.0.1:1190---10.0.0.138:80---SYN_SENT---1080

c:\windows\system32\WS2_32.dll

C:\WINDOWS\System32\WINHTTP.dll

[svchost.exe]

WTF?

I have disabled the new SP2 firewall even in the group policies, but I finaly found that the problem is with SP2's UPnP.

The UPnP without details for beginers is the "internet connection" shortcut that you can connect to the internet and when youre connected the little icon with the two computers on the lower right taskbar that you can disconnect your router from the internet.

It seems that the SP2's UPnP cant see the speedtouch's UPnP native support and so it blocks the router and I cant acces the web interface"http://10.0.0.138" or the "telnet 10.0.0.138"

So the solution is to disable the UPnP from the router and windows.

For windows go to: add remove programs-add remove windows components-network tools-click details-uncheck UPnP-click next

For your speedtouch router go to: http://10.0.0.138 - left menu click advanced-NAPT-on the right click UPnP-check off and save all

That's the solution for those want to keep SP2 and their router working until Thomson make a new SP2 compatible driver.

You will lose the convenience of UPnP but only that is the solution I found for now.

My advice for those having the same problem, send as many request and complains to the speedtouch support --> http://www.speedtouchdsl.com/userform.htm to make them fix this problem...
