Dear all users of y480/y580,

I have bought Y480. wifi (wireless) connection very slow and the line keep on drop.

there is 3 network adapters:
Atheros AR8161/.......Ethernet controller
Broadcom 802.11n Network Adapter
Microsoft Virtual WiFi Miniport Adaptert

2 of them (Atheros LAN and Miniport) are disconnected status and Broadcom is connected.

my question here is:
1. should i Disable Miniport adapter? will this impact my slow connection?
2. when setup wireless connection, we MUST put the network location (home/public/business)?

1st time using win7 too.
hope u guys can help me on this.....................

Many thanks!!!

any other setting should i check to solve the slow connection?

already uninstalled any anti virus software. now the laptop is without anti virus software. lolx

When look at properties under the SSID i connected, there is a "Enable WLAN", this 1, need to check it?

u mean this Broadcom 802.11n Network Adapter is weak 1?

that miniport adapter, when only use it?? what's the different btw miniport and broadcom? @@

what should i do with this weak card??? why lenovo give a weak card for Y480? zzz

thanks for your help..

go back will try to uninstall it and reinstall. see is it ok.

><

any command need to do after set the tcp/ip? like flashdns..
any other?

i asked the reseller help me separate my harddisk into 2 partition.

when i take it home wish to create recovery disk, only found that it can't be done with >1 partition.

what should i do now??? T.T

I have no idea. once i get it, it already like that.. should ask who? reseller? ><

why y480 dun have standard spec for this network adapter? some ppl here is Broadcom, some are Atheros.

(my LAN cable named is Atheros)

any short cut key to off the screen?

at power plan there, have Dim the Display, Turn off the display. what's mean by Dim the display? lolx

ic ic..

thanks!

if let say network adapter rosak, is it:
1. buy a new network card to replace it
2. buy a USB wifi cable

both also can be a solution right?
or there has other ways as well..

usb wifi cable, any recommend product for this?

there is too many models in market, from rm2x - rm1xx also have.

thanks for the reply!

i just chat with Lenovo support, he checked the record there and say the system shipped with Liteon wireless card for my y480.

i just @@

i only know Device Manager --> Network Adapter to see my network card. it's mention to me is Broadcom.

now this guy say i shouldn't install broadcom. zzzzzzzzzzz


i dunno how to check the REAL wireless card i using???

now at office, not able to check it.

will update here to9.

thanks for you all help..

feel tired with this kind of thing.

(1st guy tell me this: As per our database your system is shipped with Liteon Wireless card. We do not recommend you to go with Broadcom driver if your system is shipped with Liteon Wireless Card.Broadcom driver will not work in Liteon hardware. You need to install Lition driver to make your Wireless card work.)

ok..after chat with 2nd guy of lenovo support, he tell me this:
"We would like to share with you that system is shipped with broadcom wireless adapter. Yes the both the adapter are same. Please find the details on wireless adapter at your system Liteon WB195 BGN+BT HMC WLAN."


means Broadcom = Liteon. =.=

different guy tell me different thing.
