It can reach 2100Mbps in 5GHz and 1000Mbps in 2.4GHz.
Used. It works perfectly.
In excellent conditions except for the broken retaining ring on two of the four antennas (see pic #5). It's a merely cosmetic flaw, it doesn't compromise its functions in any way, the antennas can still be screwed in as firmly as the other two.
I don't have the original box.
The bundle is complete: external magnetic antenna base, low profile bracket and Support CD.
