Vaio Wireless Issues

I currently own a Sony Vaio VGN-FS740 and am having wireless issues. I will try to explain as best i can...

After time with no warning my wireless becomes very very slow, almost like it is bogged down. This is the third time it has happened but the first time i have been able to narrow it down to the wireless. The other times it has happened i have done a full system restore on the computer (i didnt realize it was just the wireless) and it repaired the problem.

It has now been about 6 months since the last time it happened and i do not want to do a restore due to the amount of programs and content located on my laptop.

i have attempted as much as i can trying to fix this problem but it seems to be past my skill level.

Has this happened to anyone else? how can i fix this. I really really really do not want to do a system restore again. When plugged into a network cable the computer runs fine BUT as i have described, my wireless is at turtle speed.

Thank you for your help!

 

Hello,
I'm wondering if your router could be at fault.
A Medion laptop had trouble with our router... and it was getting worse, you reinstalled it, and it worked...then there was some issue with the CA firewall (it had to go...)
Then disabling internet protocol 6 enhanced things...


I could think of three possebilities:

1. You computer switches off the wireless device, or reduces its powerinput, try visa the device manger, stop it from swithing it off, maybe increase the power output.

2. Your Router may cause problems. (if it wasn't labelled Vista comptible...)

3. Try running on internet protocol 4 only (settings for you network from the computer)

Oh, and PS: I assume you are using Vista, do post you operating system.

(I do have to say Vista is dodgy - so what works for me might not work for you...for whatever reasons...)

 

I would recommend getting the latest drivers for your (presumably internal, Intel?) wireless network adapter as a first step.

DevletCM's advice re: the router is good, too. It's worth checking if you get the problem on all access points or just the one you use most often. Maybe upgrade the router's firmware if you haven't already tried that?

 

i am running XP. i deleted the wireless driver and then reinstalled and it seemed to do the trick.

 

I have the same computer and have had wireless problems almost hte whole time I've owned it. Right now it wont wirelessly connect to my Netgear router, but it works with my belkin router fine. Before, the ethernet port would not work..

 

I would be tempted to blame the router, TBH. I've had problems with Netgear, Belkin, D-Link and Linksys routers at one time or other. All of the 'consumer' grade routers are a bit flaky (hence they're a fraction of the cost of the enterprise class rack mounted gear that works for years on end without a glitch).

For instance, my dad's D-Link router often refuses to hand out IPs via DHCP over wired ethernet ports, even though it's fine with wireless which you would think would be more complicated... Go figure!

But definitely update the drivers for your network adapters if you can - they often fix subtle incompatibilities quietly, I've found.

 

.........and can try to update the firmware of your router..........

 

try to set different router setting in WAN setup, under MTU default value is 1,500 and you should put 1,452. Worked for me (Dlink 524)

and here is short explanation:
you might try lowering the MTU value on your router. The MTU can be changed to accommodate fragmentation of packets; specially encoded packets with secured data can be too large for the current MTU and cause too much fragmentation.The default MTU rate is 1500, to change this enter the number in the MTU field and click the Apply button to save your settings. (Start off with 1452)
