Re: Vista Intermittent Network Connection Problems
I too am having this same problem (and its driving me nuts too). I have
a new Vista machine with a Realtek GBit onboard Network interface
connected to an unmanaged DLink GBit router using cat 6 cable, which in
turn is connected (using CAT6 15 m cable) to a Billion ADSL/VOIP/Router
with a 4 port Fast ethernet switch. The Billion is supplying a printer
and PC (Fast ethernet only) directly and the DLink switch. The switch in
turn is servicing a laptop (Fast ethernet only), PC and Brother
multifunction device. I am getting intermittent internet browser
service on the GBit PC and also the laptop. I have tested and tried the
following, with no result:
1. replacing the Dlink unmanaged GBit switch with another identical
switch (even though both appear to be working flawlessly elsewhere) - no
change
2. Pinged using both resolved name addresses (e.g. www.google.com) and
number address (203.5.45.21) and found no degradation in speed even
during the browser failure periods. Also used a ping route speed
testing program which showed good speeds to the ISP even during the
"outages".
3. tried server-provided, open dns , ISP dns and Billion as dns on
both individual PC connections and in Billion: no change
4. replaced the 15m cable - no change
5. Tried Wireshark - wow, not sure how to use it!
6. Tried Opera, Chrome, Firefox as well as IE - all same problem
7. Tried FTP - it has no problems or brownouts
8. Tried updating the Realtek network interface drivers - no change
9. Tried setting the network connection setting to only use Fast
ethernet - no change
10. Tried connecting the new GBit PC direct to the Billion - no
change
11. Got rid of DHCP and set everything up as Static IPs - no change
12. Tried to get rid of WINS but the network printers don't seem to
allow a no-WINS setting
13. Did thorough deep scans with AVG, A2Free and Windows Defender on
all PCs: no problems identified
As found by others above, if something is streaming from an already
connected website, it continues no problem. Ping and FTP have no
problem. The XP machine connected directly to the Billion has no
problems. Only the laptop and New PC with Vista are having problems and
only on web browsers. Works great for a few minutes and then "bam",
"Server is not available": only on browsers, only on Vista.
What the f@#$?
Should I downgrade to windows XP on both the laptop and new desktop?
Re: Vista Intermittent Network Connection Problems
If you have Vista, it is most likely you have Norton Anti-Virus. Norton is
known to terminate traffic on your system although you can Ping your can't
send or receive port 80 traffic. Check to see if your trial subscription has
terminated, if it has then you should uninstall Norton (completely using the
unistall tool also) and your connection will mysteriously re-appear...

ZOne Alarm also causes issues for some folks.
Have you upgraded to SP2? A friend of mine with the same scenario as
you found that SP2 mysteriously fixed it.
Re: Vista Intermittent Network Connection Problems
I don't know if I can put you out of your misery, but I have had this
now for about 5 / 6 weeks, all the same symptoms with Vista home. I have
had reams of live chat with Dell, as computer only a few months old,
They have sent me updated drivers for network adaptor, and BIOS settings
and replaced my motherboard with the Ethernet socket just in case and to
be fair they have been great, but the problem still persists. I have
been on to all the forums and checked and un checked various and many
property boxes, all to no avail. Done a diagnostics run - and even
installed Firefox. nothing!
I have been on to my ISP who kindly provided a new modem router (the
old one was only 4 weeks old) NO difference.
Please believe me when I say I have sore eyes from scanning the web for
solutions. Now I read in one forum a guy reported this to Microsoft and
they advised him to contact his ISP - hang on; we all got different
ISP's yet have the same problem, so it is apparent that MS response is a
buck passing side swerve, for want of a more unsuitable adjective
I was speaking to my pal this morning - he has it too, he's with
Orange, me with Virgin. Hello?
We have decided to give up, we reckon that it is another **** up in
Widows updates that came down about 5 weeks ago SP2 possibly, so we all
appear to be stuck till they get a fix and put in updates. If you
restore your PC to 6 weeks ago, the problem may dissapear, but it will
be shouting for all the previous updates. If you reset to factory
settings and re install Vista the same thing will occur.
So either wait and use your XP laptop or PC for any crucial web work
(buying etc.) cos it AINT affected XP with me either on the laptops or
2nd. PC Good as gold. and hope that the fix comes later. OR downgrade to
XP from Vista for a quiet life.
Hope this is useful, it may just stop a few people chesing rainbows.
