yessuz

Hi. i have Aspire 5349 with Windows 7 64.

 

latelly it started to drop wifi connnection. it is easily restored after the troubleshooting.

 

other devices (3 blackberries and tablet) holds the connection without issues.

 

wifi drop randomly, more or less once/twice per hour, regardless the load on the network.

 

Driver version: 10.0.0.234 

downloaded from chipset producer web-site.

Hi. are you using a router? Try to shutdown everything including your modem, pc etc. then wait for 30 mins then turn it on again. Maybe it will fix it. or try setting a diff or higher channel.

It seems to be a problem with all the Acers. Having the same problem with my M5-582PT did a search and stumbled across a whole range of Acer laptops all with the same problem.

 

Wishing I did more research before making my purchase. Shoddy wifi chip is kind of a big deal for a laptop.

First I would check for another nearby device transmitting on the same channel. That would explain periodic dropouts since the device will go to the strongest signal. When using 2.4GHz Wifi I try to use only channels 1, 6, and 11 since the bandwidth can spread three channels.

 

Do you have a way to see what other transmitters are near and what channel they are on ? (I use a reflashed WRT to do site surveys since Windows just tells you what is near and not what channel it is on.

 

Also have a U$6.00 Chrystalview repeater found in a drugstore (I like toys) and there are some software programs that can tell the same. I just like using the Linksys since it is plug and play.

 

Seek and ye shall find: just  checked the play store and there is a free (home) app called INSSIDER for multiple platforms that will display local networks, channels, and signal strengths. Seems to work well on my smartphone. See http://www.pcmag.com/article2/0,2817,2418212,00.asp

Hi guys.

 

I have checked the channels on Router, checked interferences, but mine was ok. I had set my WiFi on 9 - non standard channel, thus decreasing possible interferences before.

 

However, I have found that I had set my router to work on 40MHz wifi (AKA turbo N), which, actually increased the speed, however, as I see now - Qualcomm Atheros AR5B125 is not fully/faultless compatible with 40MHz network (Or at least with BT Home Hub 3.0 working on 40MHz).

 

I switched my router back to 20 MHz and it looks like the problem is solved - wi-fi is stable and no single signal drop in a week (while it used to be like once an hour).

 

So, I presume, that I found the issue.

Anyone can comfirm this?
