this is my first post here as I have been struggling with a problem with my internet for about two weeks now. I'll try to describe the problem in as many details as possible.
I have a HP laptop with Windows Vista. Recently I moved to a new home and this [rented] home included a wireless network for me, it not being shared with anyone else.
When I connect to the wireless network it tells me I have limited connectivity, or no connection at all. The weird thing is that once in every few days it will work for a couple of hours and then say it has limited connectivity again.
My wireless network has WPA2-personal security and an AES encryption type. I have tryed connecting from a list from available networks and manually connecting to a wireless network, but the problem still remained.
I have called the person who takes care of the router and connections in my building which literally said I must have been doing weird stuff with my computer and that must be the reason for it not to work (how unprofessional is that?). I said that couldn't be the problem as I don't do weird stuff and he should come look at it. He came, he tryed to connect manually and it worked. He looked at me as if I was stupid and left again. But like I said before, a couple of hours later it didn't work again. I called him the next day and again he claimed I must be doing weird stuff with my computer and that if had to come again he'd charge me. So I wen't to this friend of mine which is an ICT professional and he said there are no problems with my laptop.
I called the other guy again and asked him if it could be that my adapter settings weren't the same as that of the router. He said that couldn't be possible as the router auto-adjusts to my adapter (Intel(R) WiFi Link 5100 AGN). He suggested we install a cable connection in my home because he can't keep coming to see what the problem is (I guess he got tired of me calling him?). He came yesterday to see where he could install the cable and such. After that he wen't to my laptop to check the connection once again. To my horror the connection did it again whilst he used exactly the same method to connect as I. He looked quite pissed at me. I told him I was sure that in a couple of hours the connection would be limited again (and that happened). He was like 'Yeah, whatever.' and said I should call him to install the cables when it doesn't work again.
After the first weeks of the problems with my own laptop I got a second different laptop which had exactly the same problem with the internet. I really don't know the problem anymore and I hope someone here could give a professional opinion/answer on this.
