The hotel we are staying in has a wireless connection that is a joke, except it isn't very funny. We have tried everything we know to get it to work right, including talking with a technical support person, and having one of the managers talk with another technical support person.
This may seem odd, but try it.
A lot of hotels have weird security settings. Trying moving to a lower security level. I stayed last summer at a Hamptom in, and hsad the exact problem you're describing, righ up to no help from tech support. On day 2, UI got to discussing this problem with the girl (she's easily 20 years yonger than me, so forgive the 'girl') who was on the night desk. She told me to dial down my security settings to medium, and that would fix the problem. And it did. When I asked her why she knew thatm and tech support didn't, it turned out that she and her boyfriend had a fledgling software business. In other words, I got lucky.
If you're like me, you'e got you security setting set as high as possible. Which is a good idea. But in a lot of hotel chains, it just doesn't work. Trying moving you security to medium, and see if you connect better. Then decide if the increased risk is worth it. If there's a Panera Bread nearby, there wireless broadband works even with ultra-tight internet security.
BTW, sine you're there, get off Daniel Island and visit not only Charleston, but Mount Pleasant as well. Rent a car if you have to. It's worth it.
a) Charleston's gorgeous.
b) This is the heart of history of the USA. Charleston was the major port from bring slaves into the USA. It's where the first major battle of civil war was fought.
c) Get over the bridge and visit Mount Pleasant. You can't tell now, but a mere forty years a go, that was the unincorporated un-service Charleston suburb where the Blacks lived. Now, it's the probably the most valued, (because of development potential) land in South Carolina.
d) The food. Go out every damn night. You'll go home fifteen pound heavier, but it's worth it.
