My MacBook Air has been having wireless network problems. Yesterday

Resolved Question:

My MacBook Air has been having wireless network problems. Yesterday I lost wireless access to my printer. I managed to get that back today. Now I have lost access to the internet and my e mails. (This is coming to you from my iPad!) The MacBook can see the hub and as I said can print wirelessly. Network Diagnostics / Assistant keeps failing - looks like perhaps the ISP and/or other addresses have screwed up? HELP!!
Regards

Yes delete that, that can’t be right that is the IP address of the computer.

Bingo! Through on Safari but Mail gliched and would not down load e mails from my main e mail account from the server; it did download from 2 sub accounts! So I logged on to the host via Safari and that seems to have unblocked Mail. Weird but at least I am back on line. Muchos Gracias!!
