I have a strange situation which I have been trying to get to the bottom of for over 4 months now.
AS a result we have not launched due to this problem being the norm rather than the occasional problem…
I have asked numerous technicians questions pertaining to my situation but they all declare I have a unique situation which none have seen or heard of…
To begin with, I am experiencing these issues whether I am using 2.4Ghz OR 5.8Ghz bands.
What is a real pisser is I go to each clients site and perform a site survey using identical equipment mounted on a 3’ TriPod and 5’ Mast and all of the sites surveyed out fine.
Most sites will display the characteristics defined below after mounting the antenna to the clients home [high or low mounting elevation doesn’t matter].
System information
AP Side
AIRMatrix (OEM Ikarus) Hi-Power 400mw Ubiquite base stations.
Encryption: WPA2 PSK tkip
Preamble: short
Sectors: 16db 120 degree VPOL & HPOL PW [2 opposing POLS per tower]
Client Side
RB112/ Wistron CM9 a/b/g wireless card 65mw
Encryption: WPA2 PSK tkip
Preamble: Long (when I use short setting client won’t connect to ess)
Antenna: PW ROO2 15 & 24db V OR H POL According to desired AP
I have clients that are 3-12 miles out from the AP, some clients work and others I have attempted installing fail due to the following event:
I can establish a connection of -73 from 12 miles from an AP [19db ROO2] with a noise floor of -101.
When I run the survey I can see the desired AP and can connect.
After connecting to the ess, I open Wireless → Interface → WLAN and then select the Traffic Tab.
What happens here is wierd: While viewing the Traffic of the client device the unit remains “connected to ess” but the Traffic will drop to “0” on both TX & RX side on a fairly regular basis.
When this is happening and if I open a web-browser it will indicate there is no service available.
I have tried other Wistron CM9 wireless cards, new U.fl pigtails inside the client antenna, different RB112/CM9 systems which work perfectly for surveying a clients site but still suffer this situation when mounted to a clients home.
If this were a TI or RF interference issue then the other operators in my area would be suffering the same issues but are not!
Can anyone help me please???
I’m going totally insame trying to establish a reliable system considering this problem.
Thanking you in advance for your help and input.
