Realtek Wireless RTL8187B is unavailable after suspending, must reboot. 11.4

English Network/Internet
1

If I suspend the computer to RAM, wireless capability becomes unavailable from Network Manager. It has also randomly cut off and made itself unavailable once during normal run-time.
Bus 001 Device 003: ID 0bda:8189 Realtek Semiconductor Corp. RTL8187B Wireless 802.11g 54Mbps Network Adapter

rtl8187 56735 0
mac80211 266082 1 rtl8187
cfg80211 155017 2 rtl8187,mac80211

This is new hardware for me, and an issue I have never seen before.

I don’t know about the problem with suspend/resume as my computer cannot do
that; however, such a problem is NEVER a reason to reboot with a USB device. If
the sequence ‘sudo /sbin/modprobe -rv rtl8187’ and ‘sudo /sbin/modprobe -v
rtl8187’ does not restore networking, then ‘sudo /sbin/modprobe -rv rtl8187’
followed by unplugging and replugging the device will work.

The rtl8187 driver is exceedingly stable. For me, the connection remains up with
both RTL8187L and RTL8187B devices as long as the computer is up.

Thanks, I’ll try those. But is there anyway to fix this so I don’t have to drop to CLI to get it working? Maybe add one of these lines to the startup script or w/e.

No, you need to issue those commands in a terminal, or you create an executable
script with them in it and place an icon to it on the desktop. A terminal is easier.

Neither of these solutions work. The latter can’t be done since the device is internal.

I have moved up to 12.1 64 Gnome 3. Still have this problem. I would REALLY like to get this to work so I don’t have to reboot all the time.
