[Q] Cannot connect to Wifi after suspend

Hello,

I am quite new to both #! and Debian. My problem is that my Toshiba laptop doesn't connect to the wireless network after resuming . After restarting it is back to normal.

Here are the details of my system.

Linux crunchbang 3.2.0-4-686-pae #1 SMP Debian 3.2.41-2+deb7u2 i686 GNU/Linux

Also, the wifi-card in question was not detected when I installed #! . I had to manually download and install the driver for it to work.

02:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device 8723
	Subsystem: Realtek Semiconductor Co., Ltd. Device 0723
	Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-
	Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
	Latency: 0, Cache Line Size: 64 bytes
	Interrupt: pin A routed to IRQ 17
	Region 0: I/O ports at 2000 [size=256]
	Region 2: Memory at 88400000 (64-bit, non-prefetchable) [size=16K]
	Capabilities: <access denied>
	Kernel driver in use: rtl8723e

Any suggestions or fixes are welcome!

Re: [Q] Cannot connect to Wifi after suspend

Does the card work again after you modprobe the wireless module manually?

sudo modprobe rtl8723e

Its looks the module is loaded.

`--> lsmod | grep rtl8723
rtl8723e              163387  0 
rtlwifi               100668  1 rtl8723e
mac80211              171389  2 rtlwifi,rtl8723e

I noticed this in the kernel messages.

[  447.675571] wlan0: authenticate with xx:xx:xx:xx:xx:xx (try 1)
[  447.677283] wlan0: authenticated
[  447.678096] wlan0: failed to insert Dummy STA entry for the AP (error -17)

For now, I am using the tether via usb from my phone. Need to get longer Ethernet cables  sad

Re: [Q] Cannot connect to Wifi after suspend

Install the latest kernel from experimental to see if the problem is solved with that kernel.
See this post for instructions.

This is non-destructive. You will be able to boot into your current kernel as long as you don't remove it manually.

I am having the same problem, but unlike OP, the following instruction did not work on mine. I have the same wireless adapter as him, I am using a Toshiba Satellite C850-B559

this is what I get after I did what you instructed

sudo modprobe rtl8723
FATAL: Module rtl8723 not found.

also, when I run rfkill this is what I get:

rfkill list
0: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no

I found other thread about wi-fi problem but they all have their wifi or wlan detected

Hi dave13,
most of the activity here has now moved to the BunsenLabs Forums. I think you'll get better help if you sign on and post your support question again over there.
