[RT] That ***ALMOST*** works. Thanks very much. The only WiFi device that
the machine now sees is the USB device. The remaining flaw in the
ointment is that when I close the lid on the laptop, it seems to stop
seeing any available networks. When I clicking on the networking icon
it indicates "Wireless disconnected" and does not list any available
network. (Previously it indicated that the USB device was disconnected
and listed available networks under the internal device.)
I thought I might try "sudo ifup wlan0" --- no idea if that really makes
sense, but it seemed like something I could try. However it just
complains that it can't find the network "UoA-Guest-WiFi" which is
a network available when I am at the Uni. Whereas I was doing this at
home and wanted it to use my home network (called "belkin.aaa"). Dunno
if it would've worked anyway, but.
It finds the available networks OK upon boot-up. It's just after
closing and re-opening the lid that they all disappear. Can anyone give
me a recipe to tell it to find the available networks? Seems to me that
this should be do-able.
cheers,
Rolf
P. S. I can't actually work around the problem, in a shaganappi way,
without rebooting. If I unplug the WiFi dongle, plug it back in, and
then click on the network icon --> Connect to Hidden Wireless Network ->
Connection (downarrow) then I'm given a list of networks. I can then
click on belkin.aaa. It spins the wheel of death for a while, then pops
up a window saying that a password is required (although the password is
stored in the connection information). I just click on "Connect".
It usually pops up that window again, I click on "Connect" again.
Sometimes that gives me a connection, sometimes a third or forth try is
required. Eventually (so far) I get through. Not impossible to live
with, but not really satisfactory.

Kernel mentioned at the beginning of the thread:
3.3.4-5.fc17.x86_64
and
Probably the last official kernel for Fedora 17/EOL:
…/fedora/linux/updates/17/x86_64/kernel-3.9.10-100.fc17.x86_64.rpm
Do you notice the obvious?
At least update the existing version.
I'm pretty sure that this is a red herring. I had the device *working*
under the 3.3.4 kernel, so the aged kernel wasn't the problem. The
problem was the the device would "see" available networks on boot-up but
would no longer "see" them after going into hibernation (I *think* it's
hibernation that it goes into!).
Be that as it may: I have recently (due to a disaster that I
instigated, the details of which I will not go into) had to reinstall
the Fedora system. It now has kernel 3.9.10-etc. And thereby has
arisen a new disaster. I can no longer get the driver for the ASUS
USB-N10 to build. The "make" fails with an error (a whole mess of
output which is incomprehensible to me). With the 3.3.4 kernel the make
ran seamlessly. And yes, in case you ask, I *did* put the source of the
3.9.10 kernel into /usr/src/kernels (using yum install kernel-devel).
The name of the directory corresponds exactly to the output of uname -r.
So I kind of followed your advice --- to update to the "existing"
version --- before I received that advice. And disaster resulted. My
USB WiFi device is no longer usable at all.

Device - built-in WiFi card, supposedly unsupported:
"08:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd.
RTL8188CE 802.11b/g/n WiFi Adapter [10ec:8176] (rev 01)"
Is it really so:
$ modinfo
./kernel-3.9.10-100.fc17.x86_64/lib/modules/3.9.10-100.fc17.x86_64/kernel/drivers/net/wireless/rtlwifi/rtl8192ce/rtl8192ce.ko
| grep -iP '(?=.*10ec)(?=.*8176)'
alias: pci:v000010ECd00008176sv*sd*bc*sc*i*
Firmware:
./linux-firmware-20121218-0.1.gitbda53ca.fc17.noarch/lib/firmware/rtlwifi/rtl8192cfw.bin
I have no idea what you are on about in the forgoing. It is all Greek to
me. Sorry to be such a thicko, but I am one.
[poma] Once more recommendation:
# yum update
I have, as I said, just re-installed Fedora 17, and in the process was
prompted to update a brazillion packages. Which I did. Now "yum
update" produces the message "No Packages marked for Update".
[poma] I have an idea what you could try, but I need information about the
module USB WiFi device uses, therefore c/p s'il vous plaît:

For what it's worth. But as I said, I cannot get the USB WiFi device
to work ***at all*** now, so this is probably all irrelevant.
[poma] Can you confirm whether this is indeed a problem with the system
hibernation(suspend to disk) or is it actually a system
suspension(suspend to RAM).
Sorry, I have no idea. I close the lid, and the screen goes black.
Open the lid, the screen stays black. Press a key, and the lights
come back on (but wireless connections are lost. Or at least they
***were*** lost when I had wireless connections! I no longer have any
such.)
Thanks for giving this some thought. I really do appreciate your
effort. But I'm afraid that my only recourse will be to sell this
<expletive deleted> Toshiba and buy another brand which has a WiFi
device compatible with Linux. I gather that they ***do*** exist.
I will take a financial bath by so doing, but I guess that's what I have
to pay for being stupid.
cheers,
Rolf Turner
