Wireless Problems between Linksys WRT54G Router and Sony Vaio VGN-FE870E/H Laptop

[ofarrell.michael]

I recently bought a new Sony Vaio VGN-FE870E/H Laptop with Windows
Vista Home Premium Edition installed. I've since had an issue
connecting to wireless networks that use a Linksys WRT54G router. I
use this router at home and two of my friends do also. Everytime I
connect my laptop to these routers the router drops the Internet
connection and resets itself and it does this every 4-5 mins. However,
I do not have this problem on other wireless networks (school, hotels,
etc.). Also, other laptops that use XP/Mac connect to these routers
without any problems. My laptop is the one causing the conflict.

I've tried everything I could think of. I called Linksys many times
and they tell me this router as been tested an is compatible with
Vista. I also called Sony and troubleshooted many things and they
claim the problem to be with the router.

Can anyone help?

TY.

You may want to use static IP instead of DHCP.These search result may help,

ofarrell.michael, S Malin, and Tyler:

Differences in the networking stack between XP and Vista have exposed a lot
of router bugs which were hitherto hidden.

Vista uses UPnP much more heavily than XP ever did, and we've found that a
lot of routers have suboptimal UPnP implementations, causing them to crash.

1. Does this happen on both a wired connection to the router AND a wireless
connection?

2. when Vista "loses" connection, does it come back automatically, or do you
have to reboot your router? Do the other xp machines also lose
connectivity?

3. If ONLY the vista machine loses connectivity, then there is an issue with
your vista machine. Make sure your drivers are all up to date. If
wireless, make sure you have the latest drivers for your card. Go to
linksys' website and verifiy that what you've got is the latest.

4. While you're there, make sure you have the latest firmware for your
router. We found a lot of bugs in router firmware during development, and
the vendors posted a lot of firmware updates.

5. Then, try running the router tool at
http://www.microsoft.com/windows/using/tools/igd/default.mspx, and see if it
passes the tests.

If we can narrow the issue down to your router, that is, that when Vista
loses connectivity ALL the machines (xp too) lose connectivity, then there
are some things worth trying:

A possible solution worth trying is to turn of UPnP. This can be done on
the router (you would have to log onto the routers config page, find out
where it has the UPnP on/off switch, and turn it off) or from the machine
itself.

You can also try disabling window scaling.

So, please try these out:

1. Go to the webtool, and when the test is finished, click on the "view
detailed report" link, and copy that data off & save it.
2. turn off UPnP, either on the router or on the vista machine:
from an elevated command prompt,type the following:
a. sc config SSDPSRV start= disabled
b. net stop ssdpsrv <or> reboot the system
3. Try your test again. If it still fails after some perioed of time, turn
off Window Scaling:
From an elevated command prompt, type the following:
a. netsh in tcp set gl auto=di
<no reboot required>

I'm sorry you're experiencing trouble.

If the Vista works one router but another, I would check the firmware first.
Or check this post. Please post back with the result.

Vista Wireless disconnects ...a Linksys wireless router. the WRT54GS. i
updated the firmware to the most current. still nothing. if i let the router
sit with Vista off, the router ...

As far as I know the only way to disable IPV6 is go to your network adapter
properties and uncheck the box

 

[Barb Bowman]

what wireless card is in the Sony? Do you have the latest driver for
it? What kind of security are you using on the router? (at least
WPA, right? If this is the Intel 5100 wireless, you need to use
WPA/WPA2.

I have a 54G v6.0, with the latest firmware (v1.02.5 build 002, Jan. 9,
2008). My Sony VAIO (VGN-NS140E) had difficulties from the very
beginning. I tried disabling IP6 and messing with the router DHCP
settings, but to no avail. I was really hoping the latest firmware would
fix the problem, since Linksys notes:

Firmware 1.02.2
- Resolves issue of working with DHCP relay agent.
- Resolves interoperability issue with WAP54G (repeater mode).
- Resolves issue with UPnP.

I was able to have some success when I dropped the network from G to B.
I no longer lose connectivity, although I do have occasional trouble
getting connected. I often have to wait to get connected before I do
anything, or else I have to restart in order to get a connection.

I used to have an XP laptop that never had any issues with wireless
connectivity, so this is very frustrating. The router doesn't seem to
have anything wrong with it, and neither does the laptop. My desktop
that connects to the router is still XP, and I'm probably just going to
wait for Windows 7 to upgrade my desktop and router.

sorry, you are replying to a very old post and I don't see where you
posted your original issue.

Actually, I have my security set to WEP (after reading enough that would
lead me to believe anything I transmit can be decrypted, even if it's
WPA). I will change it and see what happens.

I do have an Intel 5100, and I don't have the latest firmware (I did
when I got the laptop). I'll upgrade that too and post back.

Thanks!
-Matt
