I have had lots of connectivity issues that I appeared to have resolved over time but is anyone experiencing this..

Sometimes the internet won't connect and neither will Mail.

I go through the whole gamut of local fixes but to no avail.

I then go to my iPhone/Mail...it downloads new mails and when I click on Safari on my iMac..bling...I get connected.

Is there a conflict involved here or is my ISP not up to scratch?
