Hello all,
I am having a problem that I could read in many other posts is about the same (high ping) but I have another question that is making me nervous: my wireless clients are getting disconnected from a wireless network (mikrotik) without a reason and, when they try to come back, the wireless network do not allow them I put this kind of message in the wireless info log:
May 3 07:48:58 192.168.160.5 wireless,info elj02: data from unknown device 00:40:F4:XX:XX:41, sent deauth (31 events suppressed, 71 deauths suppressed)
This box (it is a common PC, Pentium IV, 2.0 Ghz with 512 MB DDR RAM) has 4 wireless pci adapters (D-Link DWL-G510 with atheros AR5212) that I call ELJ01, ELJ02, ELJ03 and ELJ04.
All system uses setorial panels, 90 degres, 12 dBi. Wireless networks ELJ01 and ELJ02 are in the oposite directions (180 degres a panel from another) and ELJ03/ELJ04 are 90 degres from ELJ01/ELJ02. This way I can cover all 360 degres from this POP.
The problem, first one, is the dropping wireless. This is happening in all the wireless networks. I tryed to reboot the machine: do not work; I tryed to shutdown the machine: worked for about 2/3 hours, them the problem starts again.
I have gone to university last night and, when I get home, I tested the network I was connected to… It was too slow. Pings with more tham 1000ms. I changed my equipament to another SSID (I was using ELJ04 and moved to ELJ03 that, in my Gi-Link WA2404, was with better signal) and my pings come back to 10~22ms.
Now, its morning here, I was testing again and two of my very problematic cliets are getting very good latency:

This picture shows my APs Survey. In this one is the channels I use. My home is in front of the network ELJ04 but my better signal came from ELJ03. I can not understand this (I have gone to the tower and I am, for sure, known that the panel connected to elj04 pci card is the same that points to my house!):
If anyone here can help me I will be very glad. I am going to the POP to test another situations.
Thank you all that are reading this post.
