Internet works, local ping / network does not!

Iv got 2 computers, 1 xp-sp1 second xp-sp2. connected on a linksys befsr81 dsl router.

On the xpsp1 everything works fine.
xpsp2, DHCP doesn't work, so i have to assign. After assiging 192.168.1.5,  I cannot ping the router (192.168.1.1) neither can i ping the other computer. The other computer can't ping me either. The internet work fine!
Its not a hardware issue because when i boot on a different partition with a clean xp on it, it works fine.
The most interesting part is, if I cannot ping the local network, how can i get on to the internet???

I installed sp2  about 3 weeks ago. I dont know why, but my gut tells me its a bug in sp2.

Any answers??

Thanks in advance,
Shia

I believe SP2 reenables your ICF firewall - have you disabled that?
Is the subnet mask the same for all systems?
SB is correct SP2 Enables ICF - It puts an easier to manage Icon in the control Panel :)

I forgot to mention, ICF is turned OFF.

Subnet mask is 255.255.255.0 on all of them.

What about adding entries in your lmhost file located in start->run->%systemroot%\system32\drivers\etc (rename to lmhost without the .SAM)

i cant even ping the ip address of the local computer/router.

It will reply only one out of four, somtimes.
Mmm curious why do you say lmhosts Neal? layer 2 and three is working We've just got an ICMP problem looks like?
>>It will reply only one out of four, somtimes.

the plot thikens? can you ping the loopback address on each machine?

ping 127.0.0.1

then

ping localhost
Avatar of slevi

ASKER

>can you ping the loopback address on each machine?

>ping 127.0.0.1
>ping localhost

I can do both.
OK this tells me your TCP Stack is up :)

Your Tracert results tell me that ICMP is working (ICMP is used for ping if you were not aware :)

so your system is happily sending Ping results out over the internet and recieving them back (tracert sends three ping messages out per hop)

so the problem is truely internal - if you were gwtting a one way ping, Id be shouting Firewall! but you cannot ping either way? then my nest call would be ICF - but youve assured me thats not the problem.

DO you have Zone ALarm, BLackICE or any third party Firewall apps?
are ypu pinging th machine name or its IP address?

what im trying to do is go in to the linksys router.
http://192.168.1.1 And i couldnt go in.
so i tried to ping 192.168.1.1, didnt work either.

Just thaught i might add this info;
This computer was connected to another network until last week. The local ip address was 192.168.250.5.  (Static, because I have ports routed to my computer)
I moved in to this location/network friday, and thats when i started having this problem.
I didnt install any new programs or such, the only thing i changed was the static ip.


Thanks,
Shia
>>192.168.1.1

is indeed the default IP for Linksys :) I use a WRT54G

>>This computer was connected to another network until last week. The local ip address was 192.168.250.5.  (Static, because I have ports routed to my computer)

>>BTW, I already tried a differnt router, same result!

you have spare routers? I dont get paid enuf :)

have you tried https://192.168.1.1

Avatar of slevi

ASKER

just tried, makes no diff, as it shouldnt...

OK both work on my linksys

If its not a browser problem, (and the ping loss suggests it isnt) I think you will have to bite the bullet and hit the reset switch on the router
Avatar of slevi

ASKER

That was the first thing i did....

But its not a router problem, its the computer.
From the xp-sp1 computer i can go in to the router without a problem!
Have you tried a new NIC? (network adapter)?  Or did I miss that somewhere?
Sporadic results could indicate a failing adapter, particularly if it 'was' working before...
Avatar of slevi

ASKER

I did try a new nic, same results.
As I said in the begining, its likly not a hardware issue, because when i boot from a different partition with a clean xp on the computer, it works fine.
Just for ha-ha's, if you have another one lying around, give it a shot.
It might not be failing - but it may be poor driver support in the OS it's not working on...
Another thing I don't see mentioned - remove SP2.  We see this causing many problems as of late...

have reset tcpip, uninstalled sp2, still same problem!

RRRRRRRRRRRRRRRR
Where is this host -

1    18 ms    19 ms    17 ms  10.32.105.1

?

Also, if you connect using a crossover cable to another host, can you ping it ?

Im not sure. DOnt know.

>>>Also, if you connect using a crossover cable to another host, can you ping it ?

As I said this is not a hardware issue, because booting from a clea xp, it works great.

Guys, Im almost giving up, will have to clean install soon if i dont get an answer.

Thanks for trying everybody.

You could try using this to reset your TCP/IP and Winsock settings:

did this already, no help.
On a working build, does 10.32.105.1 turn up in the traceroute ?
Do you have anything like NAV or ZoneAlarm installed ?  In fact, ANY other security product that could be interfering with this ?

Avatar of Black0x2

All right... No need to hit the panic button yet :)

Interestingly enough, nobody's thoughts went to checking the proxy settings as far as accessing
the router from the browser is concerned... :) As far as I have read above, the TCP/IP stack
seems to be working fine, and if he is getting ping replies once in a blue moon, and if the same
machine works fine on with a fresh install, I would remove TCP/IP entirely, and then Re-Install.

So possible solution:

1. Try checking for proxy settings... :)
2. Try Re-Installing TCP/IP.

Hope it helps...

>>On a working build, does 10.32.105.1 turn up in the traceroute ?

The same IP comes up on a working build.

>>Do you have anything like NAV or ZoneAlarm installed ?  In fact, ANY other security product that could be interfering with this

Iv got ONLY NAV Corp ed. which doesnt have a firewall. I already uninstalled SP2

>>1. Try checking for proxy settings... :)

nothing in there

>>2. Try Re-Installing TCP/IP

How? (iv already used some utilities on the web for it, but there isn't a straight forwared way to uninstalll tcpip, as far as i know.)
Does your edition of NAV have an 'allowed applications' section ?

>Does your edition of NAV have an 'allowed applications' section ?

NO. It only does virus. no firewall whatsoever.
