vista wireless problems

I have Sony Vaio Z620D which runs Windows Vista Business SP1, and I use Siemens SE567 wireless router at home.

My problem is that the laptop constantly loses wireless connection to that router. This usually happens when bringing the laptop back from sleep/hibernate. The strange thing is that immediately after waking up from sleep/hibernate, wireless works fine for some short time (from 1 to 10 minutes) but then it's gone. The wireless network status however is usually shown as connected (local and internet), and sometimes it's shown as local only.

In order to re-establish connection, I usually have to manually disconnect from the wireless network and connect back again. Using ipconfig/renew never fixes the problem. Sometimes the connection comes back on its own after 30 seconds or a couple of minutes.

Sometimes, the wireless connection is shown as local only to an unidentified network and it takes several disconnect and connect back attempts to establish a working connection.

The problem occurs only when connecting to that SE567 router at home and only with the Vista-based laptop. My old XP-based laptop had no problems with connecting by wireless to the router. I suspect the cause of the problem is the combination of the router and Vista-based laptop.

I spent some time searching the web, but none of the usually suggested in such cases fixes work for me. I tried (without any luck) disabling ipv6 and unchecking the option "allow the computer to turn off this device to save power" for the network and wireless devices, and I have the power settings for the wireless set to maximum performance on battery and plugged in.

This problem is driving me crazy, I would appreciate any help.

 

i had this problem for a long time with my Compaq c501. would you happen to have Broadcom wireless, or have updated your wireless driver recently through windows update? If it's Broadcom, then you may need to roll the driver back as many times as is allowed in the Device Manager, and if it refuses to work after rolling back, go online and find your stock driver (or the earliest working driver for your wireless system) and dont allow it to update. this was the only thing that i could do to keep a stable wireless connection. I had to roll my wireless driver all the way back to the one that came on my lappy in '07, it's the only one that keeps a stable connection, uninstalled all windows update wireless updates, set my Windows Update to "manually select/install updates" and just never select the wireless service updates, as they ALL cause unstable connection.

 

I had trouble with my computer lossing connectivity to my router a few weeks back. For me, it was as simple as moving the router to a different location in the house so that it was receiving a better signal. Maybe that is what you need to do. I had thought it was a problem with my wireless card or vista.

 

I was about to post a related question about Vista and wifi problems. I don't know if it's the same problem or different, but here goes what I was about to post:

I write at a local coffee shop, and am running into a recurring problem that is driving me nuts. I can connect to their wifi, but if I stop browsing the Internet for even a few minutes (to work on something), then come back to browse, I often get a "page load error."

If I hover over the wireless icon it still says "Currently connected to..." But I can't access the Internet, I get a "Page Load Error" "Address not found" (in Firefox) or "IE cannot displaly the webpage" (in IE).

I choose "Connect to a network," and it shows I *am* "Connected," with a full 5-bars signal.

I right-click on the network, and choose "Diagnose."

It thinks, then prompts me if I want to "Automatically renew the IP address for the network adapter 'Wireless Network Connection'," or "Reset the network adapter."

Sometimes these work the first time, other times I have to do it several times. Sometimes I have to reboot (occasionally several times). (Sometimes I get "Cannot communicate with DNS server. ... cannot be repaired automatically." Sometimes I get an "IP conflict" error. Sometimes I get "Windows cannot solve the problem." Sometimes it seems to work fine for an hour or so.)

I've checked with the cafe's tech guy here, and he says it's on my laptop not their computer. Other patrons have no problems.

I have a Lenovo T500, running Vista Business (32), with an Intel WiFi Link 5300 (AGN) wireless card. All Microsoft Updates are up to date, as are drivers and BIOS so far as I know. The wifi Properties are: No authentication (Open), None Encryption, Access point, All users, Connect automatically.

Is this something as simple as needing to clear cookies each time? Or is there some setting I can tweak, to help me stay online?

Thanks for any input!

 

i had a problem like this a few months ago on an xp pro machine.
it was a conflict with the broadcom software and windows zero config.
i stopped windows zero config in services and just used the broadcom software.

just a thought

It looks like I have fixed that problem with the wireless on my laptop.

In the advanced section of the configuration properties of the wireless adapter (Intel WiFi Link 5100 AGN in my case), I changed the "Transmit Power" value from "5. Highest" to "2. Medium-low". Wireless connections have been stable since then.

 

This is exactly the same problem I had. Try changing the "Transmit Power" settings to a lower value. As I said before, changing it from 5 to 2 solved the problem for me.

 

Solved the problem finally. It had nothing to do with the laptop, OS, settings and etc. The problem was in my cordless phone interfering with the router. I guess the quality of Siemens SE567 was not very good. There were no problems after I replaced it with another brand.
