In the testing environment, both Mac and Windows 10 laptops were able to reach 200 Mbps the 400 Mbps.  Speeds are a little less in the real world but still much better than before.  Thanks to everyone who helped. ... View more

Helpdesk has not yet brought me the promised Windows laptop but I was able to grab a Mac and test with it.  Using iperf I was able to reach 200 Mb/2 to 400 Mb/s.  That's with 80 MHz bandwidth.  Not as good as I'd like it but way better than before. ... View more

@patoberli wrote: Ok great. What is the channel width you have configured on the 5 GHz interface of your test AP? Please note 30 and 43 Mbit/s are fairly close to the possible maximum you get with an 802.11n 1SS client on 2.4 or 5 GHz with a 20 MHz channel. That is in a somewhat busy environment. In a basement you can reach up to around 70 Mbit/s with the same test client. Right now it is set to 40 MHz. I also tried it at 80 MHz but I guess neither of my laptops will connect to mutiple channels. They are both castoffs nobody wanted any more so maybe they are just too old. Next week I will try to get a Windows 10 laptop to test from. The world looks way different if you go for 80 MHz channels and a 3SS client which runs 802.11ac, that can reach up to 500 Mbit/s realistically. If I could get the bigshot laptops to operate at 500 Mb/s I'd be the corporate hero of the day. :) You shouldn't use encrypted protocols (like SFTP) to test bandwidth, because the encryption can be very heavy on the client CPU and produce wrong data. I've found sftp between Linux boxes to be not too much slower than FTP or NFS. ... View more

Thank you for the reference. It is very helpful I was using SFTP to transfer files because that and FTP is what the developers are using. The transfer rates I get from iperf are consistent with the sftp speeds. EG: ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 85.3 KByte (default) ------------------------------------------------------------ [ 4] local 198.204.114.92 port 5001 connected with 10.212.56.131 port 45106 [ ID] Interval Transfer Bandwidth [ 4] 0.0-10.2 sec 35.4 MBytes 29.1 Mbits/sec ------------------------------------------------------------ Client connecting to 10.212.56.131, TCP port 5001 TCP window size: 81.2 KByte (default) ------------------------------------------------------------ [ 4] local 198.204.114.92 port 59024 connected with 10.212.56.131 port 5001 [ 4] 0.0-10.1 sec 51.6 MBytes 43.1 Mbits/sec I have to come in tomorrow evening to run some patches and I will bring in my personal laptop which has better diagnostic tools. ...

I turned it up on the test SSID I am using and it connects at 5.745 GHz but only transfers at about 35 to 40 Mb/s over sftp. I know sftp is slower than ftp or nfs but sftp is what the big shots want to use. I can get sustained speeds of 700 to 800 Mb/s from sftp over a wired conenction.  - Are you using separate SSID for 2.4 Ghz and 5 Ghz? If not, I highly recommend to do it due one 2.4 Device could slow your Wi-Fi significally. I didn't know that I could even force a SSID on the 5508 to use 2.5 versus 5 GHz. I can certainly setup separate SSIDs for most of the users. At least one SSID will have to support 2.5 because some devices on the network just do not support 5 GHz.  - Are you using RF profiles? Maybe are you using teh defailt one? If yes which is the beacon that you are using? As near as I can tell, I have no RF profiles defined. I think (wihtout the information requested) your porblem could be located on the beacons that you are using. This could cause that one client will be connected to one AP that is not the better one on that location (maybe the roaming didn't complete correclty). That could be. Could FlexConnect have anything to do with it? I use it because there are APs at remote offices that are managed by the 5508. ... View more

I used a Fluke One Touch AT to check the signal strength in the offices and conference rooms. The SSID they connect to varies from -46 dBm to -52 dBm.  The access point I am using to test registers about -45 dBm The Air Quality Reports averages 99% to 100% for 802.11a/n/ac and 95% to 99% for 802.11b/g/n. According to the 5508, the laptop I am using for testing is connected via 802.11an which, if I understand the nomenclature correctly, is 5 GHz. Everything looks pretty good to me. Using sftp, I just transferred a 1.07 G file in 3m 27s which translates to 5.2 MB/s or about 41 Mb/s. My configuration is attached. ... View more

All I really know is they are using MACs. I tested using a Dell Latitude E6540 which probably uses the built in wireless. The latop is running CentOS 6.10. The kernel version is 2.6.32.

The laptop is picking up a correct configuration for the site.   Most of the local addresses here are 10.212.X.X but the new site will be 10.214.X.X and I typed 212 in a few place I meant 214. Sorry for the confusion. I edited the original post to fix that error.   JIC, Lat night I also shut down the stack (it's still in the lab) and scanned for any 10.214.0.0/16 addresses that might be laying around the LAN.
