I have a Toshiba M645-S4070 and am seeing this exact same problem.Ībout once a day, my Internet connection dies, and the Windows 7 wireless widget says no wireless networks available. If all the above doesn't work, I suggest you replace your wireless adapter. Don't put your access point near any 2.4G equipments like cordless family phone or microwave for they sometimes cause severe interference. On top of that, make sure your signal indicator for your adapter stays more than 2 grids. Besides, I find some new 11N adapters do not work well with old G access point. Since your access point is only G, you don't need a N radio mode. Third, you could change the radio mode of your wireless adapter from N to legacy G, it's the same place as I just mentioned in the second action. Second, you said your adapter works fine for about 20 minutes, you could try to stop the power saving option in the advanced panel of your adapter interface. It's a easy action worthy to try though I don't think WEP encryption will cause deauthentication problem. Since you ask, I could provide my opinion belllow for your reference.įirst, You can try an open system which means no encryption is applied. I am not from intel, but I am a WLAN system designer who happened to see this thread when I intiated my thread in this forum. I've identified the version and updates needed for my system in Intel support tools and it generates an result saying that my Intel PROSet/Wireless was not detected. The Wireless is Intel centrino advanced-N 6250 AGN. What can i do? it is a hardware problem or software? anyone have this issue and fix it? Isn't because a conflict in wifi-wimax devices maybe? I only have like 2 months with my new laptop. I have updated the driver, unninstaled the Kaspersky 2010 (now I have Microsoft Security essentials), but even that the issue is happen.
but in the same time the failure come again. the message "wireless network connection cannot be found" appears, to fix this issue I have to restart my laptop and it start working again. my computer is TOSHIBA SATELLITE M645 S4050, it has WIFI and WIMAX together (Intel® Centrino® Advanced-N + WiMAX 6250), the issue is when I am turned on my computer, after about half hour my WIFI stop works, then I have to enable the wireless network connection.
Hi, I am having a problem with my wireless device I guess.
