Networking Problem - Browsing Not Possible After A Day or So...

#1
Hi,

I have a Toshiba M750 TabletPC running Win7 Pro 64-bit.

Never had a problem until a few days ago, possibly until I installed SpiderOak's latest version, 9810. (SpiderOak is a backup/sharing software similar to Dropbox)

I'm using IPv4 with the following settings:

Fixed IP of 192.168.200.192
Subnet: 255.255.255.0
Gateway: 192.168.200.100

DNS1: 192.168.200.144 (our SBS2003 server's IP)
DNS2: 208.67.220.220 (OpenDNS)

After I have used the computer for a day or two, IE and FF stop being able to browse, period.

This is both on a home network, as well as when using Wi-Fi networks out of the house. Haven't used the laptop in the office so far.

I have tracerouted sites, which I am able to do successfully when not able to browse.

SpiderOak is not running, but possibly any modifications to the OS/networking might have changed things. However, this could also not be a result of SpiderOak, but rather Windows Updates as well...

Other computers on the network (home) are able to browse the internet.

In this condition, I am only able to browse the net and get e-mail (Outlook) when I log into a VPN connection, and then it works fine.

This occured when I was docked in the docking station, after about 14 hours of using in the DS. Prior to the 14 hours of use in the DS, the unit was docked/undocked multiple times, including sleeping/waking multiple times.

I have tried putting in DNS1 as the gateway IP, like all the other machines have, but the laptop cannot browse or get e-mail access - no idea why.

I have tried disabling the LAN connection in Win7 and then restarting it, but this has no effect.

Any feedback is appreciated.

Edited to Add: No updates of LAN connection/drivers have been installed either.

Edited to Add 2: However, a complete OS/machine restart solves the problem and Win7 behaves normally.

Edited to Add 3: I did nothing to the computer and SUDDENLY the machine starts being able to browse and receive e-mails!! What could be going on??

Man, this is a heavily-modded forum - received like 7 PM's from a mod telling me that this was approved - and they keep coming!

(First the post disappears...now magically appears again - I thought I lost it. (the post - that is! :p))

Do you get internet on any other devices?

Yes, as I (think I) posted, the XP boxes were a bit slow, but would pull up the sites...

Other computers on the network (home) are able to browse the internet.

Sorry for not reading that bit. I recommend you do a system restore to a date when your internet was working on that pc.
