MOSPEED ------------> I do my own 'pointing up' of my dish once-a-month ...just to keep my SS maxed out (at 97).  I'm using a .98m dish, but the method for zeroing in on a satellite is precisely the same no matter what dish size you have.  (Although it's easier with the .98m).

1.  You can only move your dish three ways: Up/Down (elevation) |Side-to-Side (azimuth) | Skew (rotation)  But first, take a level and ensure that your pole is sitting perfectly level.  If it isn't ...MAKE IT THAT WAY!  lol...

I use an indelible marker and draw marks around where the washers are so that I can always find my way back to where I started (something like having a backup ...heheh), then I loosen the nuts that allow up/down movement.  I start a bit higher than needs be, then slowly lower the dish in tiny increments while somebody watches the Signal Strength until I get/find the highest signal, then tighten the nuts back up.  Then I loosen the 'side to side' nuts and 'pan' slowly from left-to-right in small increments, (waiting a full three seconds at every 'stop'), until the highest possible signal is found then tighten THOSE nuts back up.  Finally, I loosen the 'skew' nuts and do the same as the first two (except you'll probably find that there is NO need to adjust the skew by more than a "hair" to the left or right (at most).  By the time you get to this point you'll find that you are getting a much higher signal than when you started.  The key to success is to pause at every stop for about three seconds to allow time for your signal to travel the 22,300 miles out there and back ...otherwise you will 'blow right by it'! 

If you LOSE your satellite, don't panic.  You can either just return everything back to where you marked with the ink pen, or you can 'scan' the sky in the same manner that a farmer would plow a field ...one row at a time (slowly) until you find your satellite.  If you get a suddenly get a signal of about 30 but can't get it any higher, it just means you found the wrong satellite, and yours will either be slightly to the right and higher up, or slighltly to the left and lower down.  (That's how the Clark-Allen belt is arranged, in steps, with satellites being low (to the left), and climbing in a stair-like fashion as you progress to the right).

Hey, it's better than waiting for someone to show up to do precisely the same thing, and since you already HAVE a signal, you know that getting a higher Signal Strength is just a matter of moving your dish "ever so slightly" until you discover which of the three "movements" are off.  Granted, it will void the warranty if you are using a .98m dish or DW6000 ...but who's going to say that you did it?  (Dishes 'lean' or get knocked off alignment all the time by the wind)!  One morning, I woke up to find NO signal.  I went outside and saw my brand new .98m dish pointed at the ground ...that's when I taught myself how to align my own dish!  lol ....  (Besides ....you'll take FAR longer finding the best possible Signal Strength ...chances are the guy that shows up will just bring you up by 10 or 20dB then split.  He won't put near the effort into it that you (or ANY owner) would do.  SImple!  So why NOT "DIY?" (Do It Yourself).

Late Entry:  Please bear in mind that when you are messing with the Skew, you will be affecting the "Cros-Pol" (Cross Polarity) of your dish ...which can make or break your connectivity ...so just use extremely tiny adjustments when 'skewing', and you'll avert a host of headaches!

Cheers!

*There are some other (somewhat rare) things that can happen to your dish to cause problems as well.  For instance, after a dish has set for a time, the "radio" (transducer) has a tendency to 'sag', and so it is no longer precisely level or pointed at the exact center of the dish (called the "sweet spot".  Sometimes, when all else fails, it may be a matter of having to 're-level' your "radio" before the SS comes back up.

ALSO:  REMEMBER THAT ANYTIME A DISH IS TRANSMITTING IT IS EMITTING ELECTROMAGNETIC RADIATION WHICH IS HARMFUL TO YOUR HEALTH.  So ..just make darn sure that you don't go messing around that dish when it may be transmitting!  (Or, at least be BEHIND the dish (safe zone) if you must be working on a 'hot' dish).  Behind it or at least 1.2 meters (four feet) away from the transducer/emitter/radio ....whatever you wish to call it. 

IMPORTANT:  A DW6000 dish is "cold" unless it is being used ...so there is little to no danger working on one.  However, a DW4000 is ALWAYS "HOT" ...so you MUST stay on the backside of the dish to afford yourself the greatest degree of protection.

*Some people say that grounding is terribly important. The truth is that on the newer dishes, like the .98m's, the grounding achieved through the coaxial cabling is all that is needed for a good ground.  The DW4000's MUST be grounded to prevent 'static' from building up on the dish and emitter ...which will not only slow you WAY down ...but can even "cook" your transducer ("radio").  Just use the standard 10-guage copper wire running down to a copper rod driven into the earth ....no different than what is used to ground your electrical service entrance.

I guess I should mention that it is illegal to install your own dish on a Commercial System (like mine) ...but there is NO law that states that you cannot "tweak" your own property!  (There's a difference)!

Duh. never thought to hit the modem direct (using a DLink router reconfigured to 172.16.0.1 BTW).

How is signal strength of 77? Overcast evening here near JAX.

What are awesome, good, bad and ugly strengths?

Thanks a lot.

Awesome would be in the 80-90's (you won't see this unless you have at least a .92 meter dish probably), good would be from about 60's-70's, and bad would be from about 40's-50's, and ugly would be anywhere in the 30's.

Right now I'm getting a 45 (I'm thinking there's a tree in the way).

BTW, you can't get a signal under 30.
