iwlegacy and bridging iwl3945...? (sort of)

https://wireless.wiki.kernel.org/en/users/drivers/iwlegacy

('$ ethtool -i wlp16s0' says 'driver: iwl3945' but
https://wireless.wiki.kernel.org/en/users/drivers/iwl3945
links here
https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi
then here
https://wireless.wiki.kernel.org/en/users/drivers/iwlegacy
So, running fedora 21, I assume the above means my driver is iwlegacy)


Hello Folks,

I have a deceptively simply questions;
Will this iwlegacy driver driving iwl3945 hardware work as per this
How To here:
https://wiki.debian.org/BridgeNetworkConnections#Bridging_with_a_wireless_NIC
?

That How To provides (to a novice) a comprehensive explanation to the 
problem of bridging a wireless connection that seems to be universal to 
all wireless connections.  But, there are other explanations of the 
wireless bridging problem which make me suspicious it might not work...

Warning here:
http://www.linux-kvm.org/page/Networking#public_bridge

Explanation here:
http://www.linuxfoundation.org/collaborate/workgroups/networking/bridge#It_doesn.27t_work_with_my_Wireless_card.21

So, can I expect to be able to bridge my 802.11 connection to work with 
my KVM guests?

(I'm setting up an old laptop to run as a home server.)

Many thanks for your help.
Morgan.

No, never over wireless, regardless of the driver.

(Unless you also control the software on the AP and can run openwrt or
such and use the Linux-specific 4-addr mode)

Thanks for the follow up.

That's certainly a possibilty - I have in the past had Gargoyle on my 
router but, I hadn't installed it on my present router yet because it 
wasn't supported but, I see as of May the tplink c7 archer is 
supported...  Perhaps it's time for an upgrade.

However, before I go down that route are any of the options for bonding, 
which again seem as if they would work, actually a reality?

https://docs.fedoraproject.org/en-US/Fedora/21/html/Networking_Guide/ch-Configure_Network_Bonding.html

Then would the example at the bottom of this page work:
https://docs.fedoraproject.org/en-US/Fedora/18/html/System_Administrators_Guide/s2-networkscripts-interfaces_network-bridge.html
That is, bridging the bonded interfaces?
This is the most appropriate set up for my use.

Many thanks

I don't really know anything about bonding, sorry.
