Firewall rules resequencing v3.20

OK, this sounds so dumb but has anyone experienced a problem where firewall rules don't stay sequenced. We sort by rule no. close the firewall window and when you reopen it the rules are out of sequence. Acts like the rules are sorting on another column even though we sort on sequence number. Runnin...

Re: Ideas on implementing wireless mobile mesh

Just checking to see if auto tx power leveling and auto channel selection is important in your deployments. If so have you figured outt a method to achieve this? We have looked very hard at Cisco and others that have a method of adjusting tx power up and down as well as choosing the best channel to ...

We have a large number of Mikrotik AP's deployed with PW 120' Vertical sectors. We run ch 1 on sector 0, 6 on 120, and 11 on 240. We recently discovered that we are causing our own high noise levels. For example, we have tower A with CPE connecting to sector 240. We have tower b 6 miles from a on an...

We are starting equipment testing for a 42 sq mile Metro WIFI Mesh and will most liekly test 25 or so MT AP's in a test mode.

I asume the 79 and 80 is the db you got from card 1 to card 2 or visa versa. When you did you link speed test what was you noise floor and you signal level from the other end.
