We recently changed out our environment from Cisco 1100 and 1200s for the Pepwave AP One. Initially we just pulled the ciscos and put in the AP one APs in a 1-1 ratio. Verified everyone could log in and went home. The next day we were flooded with complaints about poor performance etc. Note that we used the same channels, so the only thing different was the connection method (using WPA2 now instead of a WEP/domain authentication/IAS solution, and the SSID is different) and the hardware itself. We had previously used a wireless survey tool to scope our our building and the previous wireless network was working great.
So purchased a wireless survey tool (TamoGraph) and found that it appeared the signals were overlapping enough that the signal-to-interference ratio was really high. Seemed like a simple fix so we worked that out by reducing the number of APs we are using (down to 9 currently from 11) to reduce the overlap. The problem consistently is slow performance. The tool we are using (Tamograph) will show expected and actual PHY rates of 80-150 Mbps, yet the wireless users are consistently seeing extremely poor performance and off the wall ping times (1 ms then timeouts, then >100 ms, then 5 ms consistently - all in 1 minute).
I know our 2.4 Ghz spectrum is rather clogged, though most of the additional signals are outside of our building, and we were running on the 2.4 Ghz spectrum for the past 5 or so years w/o this problem (the slowness is directly linked to the changeover to the Pepwave product, so its either the product or the config).
The last piece of information to share is I’d really like to run just 802.11n in the 5 Ghz spectrum. That’s almost completely clear, and the performance change between g and n is the main reason we switched to the Pepwave product (we were running 802.11g prior to now).
APs are controlled by a Balance 380
VLAN ID: 0
Broadcast SSID is checked
Multicast filter is off
Multicast rate b/g: 54 Mbps (we had this at the default of 1 Mbps but had terrible slowness/disconnects. Upping to this value helped a lot)
Multicast rate n: MCS7
No bandwidth restrictions
No guest protect, no custom subnet etc etc
AP Profile (we have multiple channel profiles, but the rest is the same, so I will just post the other info instead of each channel)
Location: United States
Preferred Frequency: 5 Ghz
5 Ghz protocol: 802.11an
5 Ghz Channel Bonding: 40 Mhz
2.4 Ghz protocol: 802.11n only
2.4 Ghz Channel Bonding: 40 Mhz
Power output: (varies based on area to reduce signal overlap)
Management VLAN ID: 0
802.1x version: V2
Beacon Rate: 11 Mbps
Beacon Interval: 100ms
RTS Threshold: 0
Slot Time: 9
ACK Timeout: 48
Frame Aggregation checked
Frame Length: 50000
When I log into the APs, it shows their radio to be 2.4. I don’t know if that matters or not. Seems like they may not display things the same as the management profile.
Also I have the 3.3.1 firmware on all the APs, and am current on firmware on the 380.
Please help - pulling my hair out here.
