Daily re-pointing the dish, is this normal?!?

You should not need to repoint your antenna, provided it is not so loose that it is moving about in the wind.

What is your receive signal to noise ratio ( Rx SNR ) ?
Look for a screen like this:


How does the C/N vary during the day ?  Expect a stable value like 16.4 dB if your location is near beam centre.

It is possible that your C/N is very low and tends to vary and fail at times.  This could be due to you being tuned to the wrong beam type and thus well outside the nominal beam coverage.

What is your exact location ?  Check your beam type and location here:

There are four beam types, 1, 2, 3 and 4.

Another possibility is a bad F type cable connection. The centre wire pin should stick out 1.5mm proud of the rim and go smoothly into the hole when the plug is screwed up. It should not "push back" the cable.  The outer braid connection is important also. It is possible that your connection is intermittent and that moving the antenna about temporarily fixes the bad connection.

Please tell us here how you get on.  I am interested to know that you are in Hungary.  We have had many happy cycling holidays in Hungary in recent years, see: http://www.satsig.net/velobad3.htm

Beam type 2 (orange on the Linkstar modem screen) is good for you. You are almost in the centre of that beam.  You are not in, or close to, any other beam.  A SNR =14.8 dB is excellent. Signal quality is not the problem. Leave the dish pointing alone once you are peaked up.

Regarding losing connection to the internet when you enter the modem interface.  This is probably because of different IP addresses, between the modem status screens and the internet access mode. Try doing network interface refresh on your PC. Cycling the modem power or rebooting your PC might also be effective.

Please tell us how you get on.
