BKKdreaming Posted September 18, 2016 Share Posted September 18, 2016 I have a 2 year old Dell 15 inch laptop , The Home WIFI worked good on it in the morning but a few hours later it would not work , even when the control panel says CONNECTED...... But phones and tablets work OK off the same WIFI as does an older laptop I dug out of the closet that had been sitting 2 years ..... Ummm so any idea what went wrong ? The laptop was not moved, not dropped , nothing happened that I know ????? Can a laptops WIFI card just die ? I restarted the driver but that did nothing ? Any ideas on what else I can check ? Is there a modem checker program I can downloading from the working computer and transfer it by USB card Any ideas appreciated......Thanks Link to comment Share on other sites More sharing options...
cooked Posted September 18, 2016 Share Posted September 18, 2016 TOT messed about with our router and we had problems but My iPhone and iPad now work ok after going to devices - router in the control panel and clicking 'look for problems'. Having a PC I was able to download 'OSToto' which is basically a shortcut for turning your PC into a wifi transmitter but I guess you can't do that? I have to use that for the Androids our family has. Link to comment Share on other sites More sharing options...
chrisinth Posted September 18, 2016 Share Posted September 18, 2016 Not sure which OS you are using, but you could try going into WiFi, 'forgetting' your current home connection and try connecting again by inserting the password when logging on. Also try changing DNS setting to (or from) say, google or openDNS servers. Also check your Control Panel\System\Device Manager to make sure there are no indications there. Have you recently updated your system? Might be an idea to roll back on that. Seems like the problem is with your laptop rather than the router if you have other devices connecting.

Pib Posted September 18, 2016 Share Posted September 18, 2016 Try what chrisinth recommended above, but first you might want to try below if not tried already. Alrhough your laptop may very be connected to the Wifi router you may not getting an IP address issued properly which means you are not reaching pass the router out into internet land. You are indeed connection to the Wifi router...you just can't go pass it. Try turning off your Wifi router for at least 15 seconds and then restart it and give it about a minute or two to fully reestablish a connection with your internet service provider. Now see if your laptop's wifi connection fully works. Link to comment Share on other sites More sharing options...

We had at many times either a laptop, or an iPad etc that would not connect, at different random times. I, in those cases had already downloaded another alternative, for creating my roving hotspot, as my particular connected everytime no problems. Using http://www.virtualwifirouter.com/ was quite successful; enabling one little laptop to serve all our devices (2 families in different rooms way, way down the corridors) simultaneously, password protected - even through those big thick walls of Italy's old Venicetown.

dddave Posted September 18, 2016 Share Posted September 18, 2016 Any chance your laptop was purchased in the USA? Certain WiFi channels (10-14?) are blocked on US origin computers as they are reserved for govt use. When my router reassigned channels, it assigned one of the restricted ones and I had the same situation...all other mobile devices connected but US purchased HP laptop would not. Took a while to figure out. Go into your router admin and see what channel it's on. Link to comment Share on other sites More sharing options...

mtls2005 Posted September 20, 2016 Share Posted September 20, 2016 This seems to be a common problem, with Windows 10 anyway. Seen it on many notebooks over the past few weeks, not sure if it's related to 1607? I deleted the WLAN network adapter in Control Panel, System, Device Manager. Turned of, turned on, Windows re-installs the WLAN adapter, seems to work fine thereafter. Assuming your router and internet are working fine, and you have WLAN on other devices (phone for example), this might work. Or it could be an IP address conflict where your router has handed out the same IP address to multiple devices. Restart the router, which will flush the DHCP process, and new IP addresses will be handed out. Take a look to see if you have a local IP address associated with the Dell (WLAN adapter); look at the DHCP table in the router to see if the IP address matches. Delete the WLAN network from the Dell's networking, turn it off/on, re-add your WLAN triple-checking any security pass-phrase. Link to comment Share on other sites More sharing options...

This seems to be occurring quite a lot recently, but as you are running W7, can't really blame the W10 1607 bag of worms for this. (Yes, I've had bad experiences with this as well) Glad to hear you got it back. Link to comment Share on other sites More sharing options...
BKKdreaming Posted September 20, 2016 Author Share Posted September 20, 2016 yeah , the only thing I can think of is ESET virus protector , it Updates around the time the WiFi stopped working The Windows 10 deal is scary , not so bad if you have other devices that you can look at to figure out a fix , but what if that is the only Internet device in the house , Microsoft really pushed everyone into W 10 and they became crash test dummies !
