Cannot reach www.aruba.it or read email under that domain from my Xfinity home account
It is about 5/6 months that I cannot reach www.aruba.it or read my emails under Aruba.it using my Xfinity Access home subscription. If I connect to my MObile phone everything works OK.\
Sometimes when the router is resetted by Xfinity (I see that because for some time I have no access or answer then works again) I can get to Aruba.it for like 2 or 3 hours then it does not work anymore.
I have tried to contact customer service but they run theor test and say everything is OK; I was even called by the "superior level" Xfinity service but they guy had no idea of what I was talking about and solved nothing.
Can anybody help ? I need those emails for work and I really need to access them and the aruba.it site for my work.
