If you haven't tried this yet, change channel method on the Wi-Fi signal. If you use auto channel setup, switch to manual and bounce through them to see if any one connects. I had to switch from auto to channel 6 because of my wife's MacBook doing the same thing. Thankfully everything else in the house was able to connect on this channel as well.
Have you simply FORGOT the Wifi Connection and retried ?
Of course I've already tried that, did that well before deciding to post on here!
I have the same problem periodically. The wifi will connect on the SG4 then all of a sudden the phone will tell me I have no internet. I try to reconnect, but it just does nothing, even though it says 'saved and secure'. I have tried diabling my wifi adapter in the PC, re-enabling it, sometimes that works. Or sometimes I reset the DSL router and that works (I have an app on the PC that lets me share wifi from ethernet). But far too often when this happens, nothing will help. The phone (and other devices) will not connect to wifi, so I have to restart the PC, or even do a system restore (!) to get it all working again. Very frustrating. For some reason, I think, the PC wifi gets changed in some way so the devices see it, but cannot connect. Any further suggestions are appreciated
Well, my new modems provisioning finally went through recently, so I connected it and the Linksys E4200V2 router, and I can connect my phone to it, unlike in my OP when trying to connect to WiFi with the E1200.
Not sure about my tablet yet, will eventually try it.
Do you see anywhere where I said I used the CD, there's an option once you have the router connected to download the software -- which would be newer than the CD -- directly from the router's support page..?!
The new Linksys routers do NOT let you on the 'Net until you install the software! And I'll damn well get snippy if I want, child!
This is a known issue with some routers, and Samsung blames the companies making the router, while the companies making the routers blame Samsung.
The new Linksys routers do NOT let you on the 'Net to surf the Web -- among other stuff -- until you install the software! And I'll damn well get snippy if I want, child!
