u get from who, any recommend? lowyat?

you can come to me fore y580 or y500 Full hd or hd
2.72 plaza lowyat 2nd floor.

Please remember this is discussion thread.

You can always use button if you intended to sell something, bro.

Just a friendly reminder.

May I know your wireless adapter model? Mine is using Atheros AR9485WB-EG and the latest driver I can find is 10.0.0.75 for window 7 64bit.

the above driver is for intel.. i guess u need to wait until atheros update their driver

May I know ur Wifi adapter model? I'm thinking of changing it but it seems like Lenovo have a wifi whitelist that only let the pc boot with specific wifi adapter.

out of curiosity, u model from which country? intel n2230... i tot all model uses this...

Mine is local set with 2 yrs warranty. I hope drivers can fix this issue...

Local set of Lenovo Y series all come with Atheros/Broadcom wireless adapter.

Weak wifi issue is common on Broadcom brand wireless adapter built-in models, but seems here most of the y500 with Atheros are having the same issue too.

^I remember looking through the full tear down guide of Y580, the layout of the wifi attenna is not typical (some sort of new layout scheme).
Till this day, I still strongly suspect this new layout may have lead to wifi signal interference (hence the weak wifi is not solely due to adapter) in Y580 (and may have pass the curse to Y500 )

But I don't bother to test my theory since my Y580 is also plug into LAN at home

I'm getting this card:
http://www.ebay.com/itm/140821299031?ssPag...984.m1439.l2649
to test out the signal after swapping the card. Need to wait 2 weeks for the card to arrive.

Its seem that the local set with atheros wifi adapter facing the same issue like China set (BCM4313 wifi adapter) according to chinese forum http://ideapad.it168.com/thread-2903884-1-1.html

You can try out the solution suggested by them. do let us know whether it work.

You unlock the wireless adapter white list in bios?

Follow the pics if cant get it.
Here the simple guide according to them:
Try option 2 first:


Alternatively, you can try to change your modem setting to 802.11g only instead of 802.11bgn mixed. This will limit ur wifi strength.


do let us know the status.

Nope, but it mentioned that the card is for LENOVO Bios version. So decided to give it a try.

Added on January 4, 2013, 12:46 pmI tried method 2 based on the image in the link, but there is no improvement noticed.

Method 1 wont be convenient coz I always connect to the wifi in the office/outside.

Local Y400 come with W8 and default wifi driver 10.0.0.209, you reinstall to Win7 and unofficial wifi driver 10.0.0.75?
May be its a drivers issues.
If use Win7, try Lenovo official wifi drivers 9.2.0.439 below for Y480's atheros wifi since no official Win7 drivers for Y400.
It seem Y480 user dont have any problem with Atheros wifi adapter using default drivers.

1 more question, is the bluetooth integrated into the Wifi card as well?

Bro Azsace, can you check ur lappy bluetooth module in device manager? izzit intel or others brand?

i wanna ask how to use always on usb actually bcoz
i had shutdown my laptop and charge my phone with usb cable but it didn't work

yep... intel n2230 hav both wifi n bluetooth 4.0
the model u wanted to buy only hav wifi...
y u need to buy... just set ur wifi adapter to one protokol like b... or g

n u said, if u off ur bluetooth, wifi improve, maybe u bluetooth signal interference... if u can set ur wifi channel, try to set to other channel like 5 or 11
