[solved]How can I turn my LM into wifi hotspot?

[jahid]

Seems like my wifi card doesn't support "hostapd". And it was a great pita to make it work in my LM in the first place. So is there any other way I can turn my LM into wifi hotspot so that windows pcs and android devices can get internet access?

Hi,

it really depends on 3 things:
1) your card
2) the driver used for it
3) how do you access internet on your laptop?.

Code: Select all

sudo aptitude install iw

Code: Select all

iw list

Look for supported interface modes section, where it should be an entry called AP.
and to see the driver used:

Code: Select all

lspci -nnk | grep -A2 0280

Hi,

1) MEDIATEK Corp. MT7630e 802.11bgn Wireless Network Adapter
2) rt2800pci
3) Mobile Broadband Modem

Code: Select all

sudo aptitude install iw

Code: Select all

iw list

Look for supported interface modes section, where it should be an entry called AP.

yah, the entry called AP is there:

Code: Select all

Supported interface modes:
		 * IBSS
		 * managed
		 * AP
		 * AP/VLAN
		 * WDS
		 * monitor
		 * mesh point
	software interface modes (can always be added):
		 * AP/VLAN
		 * monitor
	interface combinations are not supported

and to see the driver used:

Code: Select all

lspci -nnk | grep -A2 0280

Kernel driver in use: rt2800pci

then this should work, I'm using it with my broadcom card and ralink card.

or you can just use ICS

The first process returns:

Code: Select all

$ sudo ap-hotspot start
Your wireless card or driver does not support Access Point mode

[PatH57]

did you downgrade hostapd?
and you selected the right card?

Code: Select all

iwconfig

and it's not connected to wifi?

[jahid]

sorry aboout my previous post. My wifi driver was not ready. But now everything works in the ap-hotspot section, my android device now able to see the wifi, but it cannot authenticate/access the network. It says "Authentication problem".

[PatH57]

that depends on the settings you used.
wpa/wpa2 and what the android device does support, you will have to try (password must be at 8 alphanumeric characters)

[jahid]

ap-hotspot says its wpa and the android device supports wpa/wpa2 security. I have tried several passwords including the default password (qwerty0987) by ap-hotspot. But the android can't authenticate....

[jahid]

The password 123456789 failed too. It's frustrating at this point. Finally I thought I could enable hotspot in my computer.... but it seems it's going near to impossible

[PatH57]

send me your

Code: Select all

iwconfig

and

Code: Select all

wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && \chmod +x wireless_script && \./wireless_script

It will download a script and create a file named wireless-info.txt or wireless-info.tar.gz in your home folder with wireless information so we can see the condition of your wireless at the time. The MAC address, WPA key and WEP key are removed for your security. Paste contents of the wireless-info.txt or wireless-info.tar.gz file at http://pastebin.ubuntu.com or alternatively http://pastebin.com/ then post the link here in your question.

how is it your kernel is 3.5?
Mint 17 comes with 3.13

[jahid]

The driver for the mediatek wifi card is not installable in kernel other than 3.5. And that driver is not an official driver too.

[jahid]

hey, I see an official driver for that device is available now which supports kernel 3.13 & 3.14. I am going to install the new driver now.. I will report after completing that....
