Just a few updates which may be of use to anyone else having the same
issues...
1). As this issue persists without a truly good solution, it may be a
good idea to simply replace the wifi card with, say, an Atheros one
which works better. You can find them relatively cheaply on ebay.
2). One of the major issues that I was having was that my main Wifi
would crash internally, then whenever I tried to plug in a USB Wifi
adapter they wouldn't work either, leaving me literally without any
method of getting (wireless) internet. I assumed these two issues were
connected, however, further research has led me to believe otherwise.
I tried entirely removing the internal wifi card to see if that would
make a difference on the USB wifi cards, yet still neither of mine
worked. Further looking revealed one or two strange oddities...
phy#1
Interface wlx000f6001cb1f
ifindex 3
wdev 0x100000001
addr 00:0f:60:01:cb:1f
type managed
txpower 20.00 dBm
The interface is WAY out of convention. As explained here
(https://superuser.com/questions/1086632/wlan1-showing-as-weird-
characters#1086705), interface names are limited to 16 bytes. My theory
is that when network-manager tries to connect with this interface, it
breaks that limit. The solution suggested in that thread works, append
net.ifnames=0 to the kernel parameters in grub and suddenly all of my
USB wifi adapters work fantastically.
I have a feeling this itself may warrant a separate bug report, I'll do
some looking and see if anyone else is having the same issue/if
someone's already reported it.
TL;DR: If your USB wifi doesn't work and you get weird/long interface
names from "iw dev", use "net.ifnames=0" to fix the interface name and
take back your wifi.

Intel Wireless 7260 often crashes

Bug description:
Hardware: Acer CB3-131 Chromebook (GNAWTY) running Ubuntu Mate natively (BIOS
enabled by SeaBIOS firmware from scripts here:https://mrchromebox.tech/). Uses
Intel 7260 wifi, rev. bb:
01:00.0 Network controller: Intel Corporation Wireless 7260 (rev bb)
Software: Ubuntu Mate 17.04, upgraded from 16.10. Currently,
everything (kernel, firmware, etc.) is stock. Issue has persisted
across multiple installations.
Bug: Wifi/Bluetooth crashes and refuses to come back up, even after
multiple reboots. Issue persists across distros (Arch, Ubuntu, etc.)
When the wireless (Bluetooth and WiFi) works, it works flawlessly. However,
upon boot, it is not uncommon for the wireless to stop working within two
minutes of login time. Curiously, the GUI usually still shows being
"connected", though trying to change anything with the wifi shows otherwise.
Other times, upon system resume when wireless was previously working, the GUI
will show "device not ready" and refuse to continue. Dmesg shows the following:
[ 423.814823] Bluetooth: hci0 command 0x1403 tx timeout
[ 424.172973] iwlwifi 0000:01:00.0: Failed to wake NIC for hcmd

enqueue_hcmd failed: -5
[ 425.194593] iwlwifi 0000:01:00.0: Scan failed! ret -5
Solution: Rebooting doesn't fix the problem. Perhaps a different
firmware version will work better? Configuration settings? etc.?
Unknown.
Thanks ahead of time for the help. Let me know if there's anything you
need/commands I should run/solutions I can attempt.
