Product identification.

An FCC ID is the product ID assigned by the FCC to identify wireless products in the market. The FCC chooses 3 or 5 character "Grantee" codes to identify the business that created the product. For example, the grantee code for FCC ID: NKR-VRWL25 is NKR. The remaining characters of the FCC ID, -VRWL25, are often associated with the product model, but they can be random. These letters are chosen by the applicant. In addition to the application, the FCC also publishes internal images, external images, user manuals, and test results for wireless devices. They can be under the "exhibits" tab below.

  • @ Atheros_AR9271 deficiances notes in openwrt forum:

(There is very little RAM available inside the 9271 chip, which limits what the firmware and driver can do. I think that only a few stations can be connected in AP mode.I have used ar9170 and ar9271 in AP mode around a decade ago. Yes it technically 'worked', but stability was 'not good(TM)', with stalls left and right - and that was just servicing 1 (rarely 2) wireless clients with very casual/ minimal usage. On top of that, mk24 is right about the minimal on-device RAM, which severely limits what the device can do (iirc 8 connected clients is a hard limit due to that, but you're already in trouble with fewer than 6). Apart from all this, it's 2025 and we have 802.11ax/ wifi6 (with massive improvements even on 2.4 GHz), but ar9271 is a 14½ year old 802.11n/ wifi4 chipset... If you are looking for a sensible solution, USB (too small for Mu-MIMO and beamforming to work (antennas too close to each other, too small), not AP-centric, tendency to overheat, USB related issues (with little on-device RAM as a consequence) is not one. A cheap plastic AP would be (e.g. mt7921a+mt7915DBDC) or a decent AP-centric PCI(e) card, if you have to.)

Can act as Access Points Interestingly in openwrt they dont think usb and not ap-centric is a sensible solution.
