WirelessRudy you say that you can't see any difference between arm devices and mipsbe ones,but there is a lots complaints about packet loss in that architecture by using 802.11,nv2,nstreme.Please tell us more about it.Thanks
Exactly! Because I don't see that difference I did mention it....
Just for the sake, I ran 2 bw tests; one initiated (download, 1 tcp stream) from a rb911Lite5 ac (mipsbe) and one same parameters from DISC Lit5 ac
Ap has 14 units associated and works in 20Ce/ac protocol (All associated units are 'ac')
Bandwith test runs through 2 wireless backhauls and 2 CCR's for mpls routing towards gateway (CCR) which has a queue for each of this client set to 50Mb burst and 33 regular (we sell 30Mb)
It is also near prime time and both backhauls transport traffic of some 300 clients....
From both I run the bw test.
The rb911 has a connection rate (download) of some 270Mbps with a CCQ regurlary touching 100%. Signal is -23 (way too much but ok, It at 150 meters distance, 30 meters below.)
The DISC has a connection rate (download) of some 243Mbps with a CCQ 60-85%. Signal is -54. (This units 'looks' through a tower with 5Ghz ubnt sectors and 2 backhauls at 250 meters and the client is a 3km)
The rb911 runs a relative stable 28Mbps download (25 mins)
The DISC runs a les stable but average 23Mbps download (same time)
The AP shows other traffic from other 12 clients and is continiously showng 50-80Mbps
Ping with 256 package size and 500ms timeout:
DISC shows 25ms average with 2% package loss out of 1000 packages now
RB911 shows 13ms average with 1% package loss out of 1000 packages...
The small difference at the expense of the DISC is due its weaker signal and lower CCQ (The signal path is 15 times longer and the noise must be horrendous going to shoot 'through' another 4 sector ubnt tower. I actually picked the worse client from this sector I now realize...)
So I think the DISC Lite5ac is working absolutely fine in this 802.11ac environment. (I had the bw test running for almost 30 minutes while writing this post.)
