No wireless connection with Live+Nonfree Stretch

Postby xanadu18 » 2018-04-02 04:03

I downloaded, verified SHA256 then burned the iso of LIVE Debian 9.4 non-free installer to a DVD. Upon installation, the screen shows successful network hardware check and DHCP check. However, I then got the message about repo mirrors being failed.

I continued on and completed the installation. Upon the initial reboot, there's no wireless connection at all.

My wireless adapter is TP-Link (forgot model number) using RT-2700usb driver, according to lsusb command.

Did I downloaded the wrong installer file?

Look forward to hearing from you soon. Thanks for your help.

I re-installed Debian Stretch 9.4 using DVD1 ("nonfree firmware included"). During installation,WPA2 and DHCP connections were tested "successfully". I chose KDE interface.

However, after initial reboot, the screen shows "WiFi network could not be found" even though during installation and after reboot I chose the correct SSID and password. In fact, the SSID I chose is one of the available connections from Network Manager sub-screen.

I thought the non-free firmware for my Ralink-based wireless adapter would be included in the DVD.

This reply was posted using openSUSE Leap on the same PC, where there's no problem with wireless connection.

Any suggestions? Thanks a lot for your help.

I am at a loss.

Code: Select all
lsusb

Device ID: 148f:3070 Ralink Technology, Corp, RT2870/3070 Wireless Adapter


This adapter is in the list of wireless adapters supported by Stretch.

firmware-misc-nonfree is the latest package and is already installed.

Code: Select all
rfkill list

phy0: Wireless LAN
Soft Blocked: No
Hard Blocked: No


Please help!

networkmanager since jessie has issues with rt2870 devices among others. Try turning off MAC randomization

Hello bw123,

I turned off random MAC address feature in NetworkManager configuration file (i.e. Networkmanager.conf) as suggested in the second link you provided.

WiFi works now. Thanks a lot for your help.

:D
