blocked port problem

[Alex2]

Hi!
I am new here and I hope somebody can help me with my problem quickly.

We have 2 PCs running xp sp3 connected via wireless router. The second Pc connected wireless seems to cut out a lot over the last 3-4 days. I tried to get the router support people to help, the PC does ping alright (and can connect via the local network to the other Pc), but port 80 seems to be blocked for some reason, so Internet doesn't work.

I ran adware and Mcafe and there doesn't seem to be anything there. I tried to restore the system to an earlier date (even in safe mode), but always get the message that the restore wasn't possible.

any suggestions as to what else I can do to restore the PC to how it was just a few days ago or to how to unblock the port or figure out why and how it happens...

Thanks!!!

Please supply the following info, exact make and models of the equipment please.

Name of your ISP (Internet Service Provider).
Make and exact model of the broadband modem.
Make and exact model and hardware version of the router (if a separate unit).
Model numbers can usually be obtained from the label on the device.
Connection type, wired or wireless.
If wireless, encryption used, (none, WEP, WPA, or WPA2)
Version and patch level of Windows on all affected machines, i.e. XP (Home or Pro), SP1-SP2-SP3, Vista (Home, Business, Ultimate), etc.
The Internet Browser in use, IE, Firefox, Opera, etc.




Please give an exact description of your problem symptoms, including the exact text of any error messages.

• If you're using a wireless connection, have you tried a direct connection with a cable to see if that changes the symptoms?
• For wireless issues, have you disabled all encryption on the router to see if you can connect that way?
• Have you connected directly to the broadband modem to see if this is a router or modem/ISP issue?
• If there are other computers on the same network, are they experiencing the same issue, or do they function normally?

On any affected computer, I'd also like to see this:

Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

Type the following commands on separate lines, following each one with the Enter key:

PING 206.190.60.37

PING yahoo.com

NBTSTAT -n

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

Make and exact model of the broadband modem. Level one WBR-3460 11g wireless ADSL 2+ modem router
Make and exact model and hardware version of the router (if a separate unit).
Model numbers can usually be obtained from the label on the device.
Connection type, wired or wireless.
If wireless, encryption used, (none, WEP, WPA, or WPA2) no idea? sorry

The Internet Browser in use, IE, Firefox, Opera, etc. IE7 I did reset it as well after the problems started




Please give an exact description of your problem symptoms, including the exact text of any error messages. the PC on the wireless does only intermittently connect to the internet, the local network does not seem to be a problem, I still can connect between both PCs, also some messenger and ICQ do work. Sometimes the internet connectivity can be repaired by using the troubleshooter

• If you're using a wireless connection, have you tried a direct connection with a cable to see if that changes the symptoms?
• For wireless issues, have you disabled all encryption on the router to see if you can connect that way?
• Have you connected directly to the broadband modem to see if this is a router or modem/ISP issue? the PC is in the other room, but netvision mentioned it must be a local problem on the PC as the ping works, but somehow the port for the internet is blocked
• If there are other computers on the same network, are they experiencing the same issue, or do they function normally?

the main PC functions normally

the technician had aasked me to use: telnet www.ynet.co.il 80
this comes back with the message 'could not connect to the host on port 80'

also is there anyway to reset the PC to an earlier date if the system restore utility fails to work (even in dafe mode for any of the backed up dates).
Please help....

[Alex2]

meanwhile, I thought I should mention, I am posting this via the 'BAD' PC. I initially had some internet connectivity again, seemingly the websites that are open already do still work, but for others I am getting the can't connect error message...

during this the yahoo ping sometimes works and mostly doesn't and now suddenly I seem to get into other sites as well....

I am extremely confused. I also checked my firewall settings (nothing is set to a very high level there), but have the same problems turning the firewall off completely.

I'm confused too, don't know what to make of that.

The variability seems to suggest you possibly have spyware/malware.

Hi John,

well, good to have you confused as well.

Meanwhile I have IE running for a bit again as you can see. I deleted a lot of programs, user accounts, IE content for all users, etc,... oh, and I did run an extended virus check and it did find 4 viruses, though in the Quarantaine folder; also turned my system restore off and back on again and am hoping to get viable restore points following this.

but what for now seems to have helped immediately in the end was changing the preferred DNS server to obtain DNS automatically.

Not sure at all if I was allowed to do that, does that have anything to do with Netvision?

Hopefully it will keep working this way but also why has it worked before and wouldn't over sudden?

Wish me luck

[johnwill]

Good luck. Not sure what was going on...
