Help!!! MAC -Disconnecting from internet

There's something wonky with the Mac's Wifi. I'm tethering off of my iPad or iPhone, which, like yourself, have no problems connecting. My MBP is a brand new i7 15". it was happening in Yosemite, and now in El Cap as well.

So yesterday afternoon, during a call with someone, somewhere form Apple, I had gotten the idea to look at the Channel setting in the modem/router (an EasyBox 802 model). To be fair, it came form something that the tech guy said, but only in so much that it was something he said that only Vodafone could change. Anyway, I went into the EasyBox settings (at the time, from my iPad, because the MBP couldn't connect), and changed the channel to 3 (a number I picked for no reason) from the Auto setting it was on. Knock on wood, etc., etc., I've had a trouble free connection for about 24 hours now, after a couple of weeks of intermittent at best service. Do I think it's an EasyBox/Vodafone issue? Absolutely not. Clearly something is different in the way the MBP is dealing with Wifi networks.

To remind everyone, especially (hopefully) the Apple guy or gal that may read this, my iPad, iPhone and WLAN Printer (Cannon MF-4780w) never had a problem connecting. And fortunately, the channel change seems to not have effected these devices at all.

Same problem with my macbook pro Mid-2010....

I dit the upgrade to El captain, I deleted all my hard disk (clean instal...)... But the problem still..

To be clear, I'm connecting to my wifi but after 5 minutes I can't open any website... Safari said : No connection...

And I tried a lot of Wifi (Home, iPhone, School, at work.... all same problem)

Please Apple, do something...

Yeah, it has nothing to do with apps, HD, etc.... Remember, it worked fine up until a certain hardware/firmware/software upgrade from Apple. I almost wanted to laugh if it weren't so frustrating; the first guy that I spoke with tried to get me to do a HD check from Disk Tools in Recovery mode! I mean, really?!?

Anyway, as I've said, it's been working, knock on wood, since I changed the output channel on the router. If anyone's interested, I found the log-in info on the Vodafone website, so it's no harm to post it: username is root. And the password is 123456. That simple.

Maybe changing the channel on any router would work? Of course, as always, your mileage may vary, and no warranties, no guarantees... and this was a private home network. Take the info always as a suggestion.

:-)

I will try with my Wifi at house..

But with my iPhone, at school or work.. Impossible^^

Thank you

So your iPhone also has a problem connecting? One of the things that made it clear to me was how my i-devices and printer never had a problem connecting to the router.

Sorry for my English !

I tried different wifi (hom, school, at work.. And my iPhone in Hotspot) always the same problem !

If you're asking about your iPhone's Wifi problems, that's not what this thread is about. I'm sure there are plenty of discussions about it, though.

Hahha sorry for my english ! I repeat

my MacBook is connected to the wifi but after 5 minutes I have no connection more but I still connected to the wifi....

I tried different wifi (using my iPhone as Hospot, wifi at sch or works) ! And same problem! Hope you're understand
