All of these computers only have have ONE common denomenator so by basic logic and troubleshooting I have limited it to Intel being the issue. I have an industrial D-Link Router that is configured properly and has the most up to date firmware so please do not give me a list of things to do with my Router. I am having the same problem, I have four different computers. Annoying solution, but this laptop was such a bargain I won't be too dissapointed. Otherwise, I'll just buy an expresscard or USB wifi adapter and disable the internal card completely.
He's absolutely right that changing the type of encryption or the wireless protocol being used might avoid whatever firmware call is triggering the hang. I'm moving overseas shortly, so if the problem comes back, I'll try some of the suggestions mentioned by the wifi engineer. Given what I'm hearing, I'm skeptical the problem will be gone for good, but I figure I'll give it a shot. I just went through Toshiba Tech Support - there is no web/email form, but it took about a 15 minute phone call to get a return authorization. I also have only installed the 802.11-N portion of the driver, because I likewise found the WiMAX driver troublesome and pointless as there are far better broadband options in my area. To me, this indicates that heavy amounts of network traffic increase the likelihood of the problem occuring. The problem can occur at anytime, but I have noticed it seems to happen most often just after resuming from standby or while video conferencing on Skype. Therefore, I believe it must be a hardware issue.
#How to fix intel centrino wimax 6250 driver not working install#
It has occured with the Toshiba factory image, and with a completely clean install of Windows 7 Professional + the latest Advanced-N + WiMAX 6250 driver from Intel. Mind you, the problem has occurred while connected to multiple different routers. The only way to un-hang the card is to restart the entire computer. I cycle the power on the wifi card, but it doesn't come back online. I go into the network devices in the control panel to try to disable and re-enable, but the device doesn't disable. 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.
