Lol. You didn't see any real operator class router if you are willing to name this board like that. "real operator class router" costs 10-20 times more. For me, CCR delivers good enough performance. Especially considering it's cost. I hear what you say, but I don't understand the problem. If you pa...

Re: Mount HP Omni upside down?

Or you could use a daughter board on the RB600.

The omni's signal patterns differ quite a bit, especially in 'signal elevation' I'll call it. The higher the gain of the antenna the less the elevation is normaly.

Re: Mount HP Omni upside down?

Check the antennas signal pattern. But in you case I'll mount it lower. It will catch less noise and the chance of signal going over your clients is smaller. For hotspots I usually use a 12 db yagi pointed into the ground. If I was in your case I would use 3 yagis pointed 120deg from each other. as ...

At 400-500m it should work fine. But the only thing you are going to do by putting an omni upside down is giving it a greater chance of getting its internals wet, because its not the way it should be mounted(not that I gonna care, the only good onmi is a broken one).

Re: Script to change Adsl accounts

15 accounts.

Problem is a route must change the moment the account is capped. There is already 10 pppoe active in anyway(some for local, some for voip, some for dns, etc)

Problem with uncapped is its slower than capped. And for proper uncapped its R5000 for a 1mb line. Not worth it imo.
