Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I think the crucial thing about the case might be the error message about the router/access point channel conflict.
Wireless transmission and reception (WiFi) has 'channels'. This is a setting on the router's setup, and also perhaps on your device or devices in the WiFi settings.
If channel conflict occurs, either you added a new WiFi device with the wrong channel and it is making waves... radio waves... that interfere with communication, or - more likely - the router has spontaneously changed to the wrong channel, diminishing or stopping communication.
1. Check the channel settings on your device incl. laptop, first, and make sure they agree on a channel. Channel 6 is usual, I think. Or Channel 11.
2. go into your router's admin setup utility, and set the Channel for the WiFi, there, to match.
That will (with perhaps a total shut-down and turn-Off of all devices, for 5 minutes all together, then powering the router On and letting it initialize for 2 minutes, then turning On the other devices) probably solve the problem.
The router really is where the change would be needed, I think.
WiFi channel may be an obscure setting on some handhelds. But *if* the WiFi channel might not be changed on them, then it must be set to a standard channel value, and the selection on the router must have changed, and thus the channel on the router needs be changed back.
Open a web browser on your computer.
Enter the IP address of your local router in the Address field and press the RETURN key.
You should get a popup prompt for username and password. This is normal when accessing a router's settings... for username, enter
and for the password... whatever the admin password ***** ***** to. If it is set to a default value, such as
or just a blank, no characters... then that explains your problem: with a default password, anyone within range of your router (several hundred yards theoretically) could access the router's settings and change them. In any case, log in to
and whatever password ***** have, or that works, then go into the WiFi settings, note the channel setting, and set it to 11 (or 6 perhaps.) Those are most likely to work best and be fastest, and if the setting is anything else, it has most likely been meddled with.
IF that restores your wireless communications with all devices, once you have set it that way and Saved the changed setting, please go back to the admin setup of your router, and change the password (the 'admin' password, NOT the wireless password ***** passphrase or encryption key... the distinction is important.) That way your router settings cannot be changed by any stranger.
If you never set a password ***** the router, then it should be a username of
and a password *****
or just blank, no characters.
But if the connection is being refused, then you cannot enter any password ***** doubt! So, determine the IP Address of the router for sure by opening a
and entering the command
and pressing the RETURN key, once. Read off the Default Gateway address, and that is the address of your router.
Enter that address in your address bar. Try it.
