Please circle back here and post any possible solutions for the issue here in these open forums so that all readers here may benefit from the exchange / info. This is in keeping with the spirit for which these public help forums were originally intended. Thank you.

Thanks all - the issue seems to have resolved itself after I put in a support ticket. For awhile I could not get to the sites mentioned. Then I could only get to them on the 2.4GHz band but now all seem to work on both 2.4 and 5GHz bands. Will circle back if it comes back.
