I did a big mistake updating to 4.11. So called crappy Xradio has been working great for me with 4.10. Is there any possibility to undo the update?

I like the case! I just printed one. I flipped the colors. Seemed more sense to make the orange design in orange.
I had to do a little trimming on the antenna hole and around the USB jack--near the back, mine have a fold that sticks out a tiny bit, maybe 0.2 or 0.3mm. 30 seconds with a hobby knife and it fit together just fine. I used M3x8 self tapping screws instead of machine screws--because I have a ton. They worked just fine.I would like you post, but I just signed up for the forum to make this reply and I guess the forum doesn't trust me with that kind of power, yet. So, here's my verbal thumbs up to you!
Thanks, yes - slight connector placement inconsistencies from board to board are expected but nothing major. The bigger USB connector on mine has a twirl of about 7 degrees from the pivot but still fits fine.

Designed a case for it. Available on thingiverse if anyone interested - http://www.thingiverse.com/thing:1918590

It's probably a problem with interrupts. I suspect the latency you are seeing is because interrupts aren't waking up the driver so it's only reading data when it wakes up when waiting for an interrupt or tx event times out. Take a look at /proc/interrupts. I think with the legacy kernel the wifi interrupts might be grouped with MMC1.

Which version of the xradio driver? Anyhow you are probably missing interrupts.
The one that came with latest Armbian:
zero@orangepizero:~$ sudo modinfo xradio_wlan filename: /lib/modules/3.4.113-sun8i/kernel/drivers/net/wireless/xradio/xradio_wlan.ko alias: xradio_core license: GPL description: XRadioTech WLAN driver core author: XRadioTech depends: mac80211 intree: Y vermagic: 3.4.113-sun8i SMP preempt mod_unload modversions ARMv7 p2v8 parm: macaddr:First MAC address (charp)

Got mine delivered (Lahore, Pakistan) earlier this week but only just managed to test it. Everything is running smooth so far except wifi which has huge latency problem. Tried disabling power management but no luck. I know it's just early days with xradio driver but is this known issue?
Some info and ping results:

Well, here is a hardware based solution. I modified the 3d case and added a usb port via usb to dip 2.54mm board and plugged in cheap Ralink mt7601u dongle which I prefer over typical realtek ones. The on-board wifi can be used anytime, too. The case can be downloaded from thingiverse: https://goo.gl/r6E6u9
