Over a month passed, since I started writing this document, while creating the access point took me only three days.
During the time being the AP did not drop one connection, while providing coverage over almost a 100 meter diameter. No timeout error messages occurred, which was so common for the "Linksys SRX 200" router.
Over 30 of my neighbors started using it more or less heavily and some really heavily.
For example, while writing this:
root@acer:/var/log# cat /proc/net/ip_conntrack |grep tcp -c 565 root@acer:/var/log# cat /proc/net/ip_conntrack |grep udp -c 76
And even in a moment of heavy load, like below, not only does the network remain stable, but it also provides a descent speed for everyone.
Now I have comprehensive log files like:
Nov 21 21:29:49 acer kernel: [420579.216945] RULE 3 -- CONTINUE IN=wlan0_0 OUT=br0 SRC=172.17.128.154 DST=184.108.40.206 LEN=40 TOS=0x00 PREC=0x00 TTL=63 ID=58669 DF PROTO=TCP SPT=49604 DPT=80 WINDOW=0 RES=0x00 RST URGP=0
All in all I am satisfied with the outcome. It was worth the effort, and the result surpassed the best of all my expectations.
