Connection issue error 106

Hello everyone, for the past 2/3 days I have been having a problem with my PC. Overnight, the wifi network connection stopped working and it tells me that the connectivity is limited or nonexistent and displays error 106. Anyway, I check that my wifi card is properly installed, okay, I restart my modem, it doesn't work either, then I decide to call my provider, who makes me do different manipulations, and after several failures, he tells me to perform a system restore because according to him this "bug" comes from a Windows update, so I proceed and great, after the restore it works! except that every time I turn off my computer and restart it, there's no internet access and the same error code appears, so it's getting quite annoying to have to do a restore every time I want to go online!! Does anyone have a solution to this problem?? thank you!!
For your information, I have Windows XP and my wifi card: Trendnet 150 mbps wireless PCI adapter, normally it is well installed since it was working very well two days ago!
