Important note: wifi chipset/USB sticks and internal wifi chipsets should be evaluated concerning their Linux compatibility and not needing to compile source code before buying them.
TLDR
For creating an wifi AP, the most cost wise path is buying an openWRT compatible AP.
For having a more stable wifi connection, choose a notebook/iOT/router device where the WiFi chipset is not internally connected to the USB controller. Avoid realtek.
If having an internal realtek card, try to buy an internal replacement card compatible with the model of your machine based in atheros, broadcom, ralink or Intel, in that order of preference - I suspect Broadcom has the better quality/cost ratio, your mileage may vary. (Important note: your vendor might whitelist wifi card models, in which case you are at mercy of compatible models - HP, Dell and Lenovo are known for this, so check the brand/model of the notebook if you already own it)
Adenda: Usually users report the realtek chipsets work "well" in Windows because Windows drivers have nasty hacks to work around some of the bugs.
However, while they work "better", they usually work at much reduced speed/ranges and still have got problems, and in many realtek implementations, some of the more serious hardware bugs cannot be worked around.
Concerning realtek Chipsets
The ID 0b05:17ab and the string [Realtek RTL8192CU] in your lspci
output, confirms your wifi device is indeed a rebranding of the Realtek RTL8192CU 802.11n model.
I also had the Realtek RTL8192 in my ARM server/Lamobo R1 at home, which is the same chipset as your ASUS USB-N13. (or put it other way, ASUS USB-N13 rev B is an ASUS rebranded RTL8192CU).
Believe me that I have tried to do something with it for quite a while as you can see in post #23 of this thread
The chipset is junk. People who own the Lamobo R1 have totally given up in doing something useful with it.
Firmware bugs, drivers bugs, bugs in energy management that are prevalent and ubiquitous across most of the cheap Realtek chipsets revisions/models, that oblige you to use it at slower performances than the allowed by the protocols.
Even after trying to work around the bugs, you have frequent and inexplicable crashes - or more exactly, the wifi module misbehaves and then you are left with the filesystem in read only mode wondering what happened.
I also bought 5dB antennas to try to improve it.
I even also bought again a realtek nano USB wifi that proved to be even more disastrous; it started heating and stopped dead in it´s tracks for a few seconds at a time both in Windows and Linux systems.
The efforts and hassle to make realtek wifi cards working "properly" are not worth the trouble.
I gave up on trying to use my R1 with a realtek as an AP and bought instead an AP from TP-LINK - an Archer C7 v2 which I flashed with OpenWRT. (https://openwrt.org)
If you still want to have a go at the Realtek/ASUS, if in hostapd mode, in /etc/hostapd.conf you have to use
wmm_enabled=0
which makes you lose some speed.
Using it either as hostap or as client, you also have to configure the loading of the module in /etc/modprobe.d/rtl8192cu.conf
to work around some of the bugs:
options rtl8192cu rtw_power_mgnt=0 rtw_enusbss=1 rtw_ips_mode=1
Reboot then the device for the options to take effect.
General advice about WiFi technology
As last comments, specially in WiFi, you have to pay good money to have good chipsets that work as promised.
Normally it is a requirement to have external antennas, especially to use the chipset in AP mode.
Please do take note this chipset only supports the 2.4GHz band. As in most parts of the civilised world the 2.4GHz band is pretty crowded, either you have a good signal, or you are pretty much in trouble. So this reinforces the need for external antennas.
Even if using 5GHz, as the 5GHz protocol was designed to travel smaller distances, external antennas are a must.
Also beware that whilst you might got away with only one antenna in the 2.4GHz band, you need at least two antennas when dealing with 5GHz.
I have good experiences using Ralink and Atheros based chipsets, realtek ones not so much.
UPDATE: I used to have a realtek without shielding in my iOT device, that was not used because it was so bad. I also had crashes almost every week even with the thing blacklisted by software.
Cut it physically from the board, the board can go for months up without misbehaving, and RF interference at home is also lower.
I also bought a very good 10€ no-brand ralink wifi chipset dual frequency stick in aliexpress "300Mbps Dual Band 2.4GHz / 5.8GHz Ralink RT5572N WiFi USB Adapter" so much better, but ended up buying a TP-Link router with OpenWRT and connecting it via Ethernet .
To finish my "rant" about Realtek; while deciding what 5GHz AC AP to buy, I looked at one rather cheap AP, the ASUS EA-N66 which is entirely based in realtek chipset(s). The forums are full of complaints of it locking up mysteriously a couple of times PER WEEK at least.
I would not buy ASUS or Realtek any time soon. IMO they are focused in selling cheap junk that does not work.
REVISITING this answer: in the meanwhile I learnt that there are more deep settled reasons than I knew/suspected, at the kernel/USB level, which give very plausible answers explaining the stability of wifi adapters working better via PCI/card sockets vs the instability of USB-based chipset wifis.
I also learnt the USB wifi market is mostly dominated nowadays by realtek vs ralink, and most of the other brands are just rebrands.
The USB Ralink adapter I bought in AliExpress unfortunately is also an old chipset model with its set of bugs, however between two devils, it works consistently better than a Realtek. OpenBSD manages to work quite well using this Ralink, FreeBSD still has some nasty bugs using it.
PS: I was suggested to buy a USB->PCIe adapter to be able to use better brands of Wifi cards externally. If and when I try/test it, will revisit this answer.
