    I have a 7 plus, and about the past 2 weeks, the wifi on my phone has been very incnonsistent at home. Does Apple have a way to test if it's going bad, or is it more of "it either works or it doesn't"?

    Whenever it seems not to be working I quickly turn wifi off, then LTE connects just fine. I'm on 10.3.3 still by the way.

    Suggestions?

    Thanks

    Have you called Apple support?
    My experience is they have been very helpful with any issues, even helping with my 5 year old Mac mini I finally replaced 6 weeks ago....

    While pretty fast @ 70Mbps (for my podunk town) I’ve also found that my home internet provider at times is inconsistent as they are “improving” services, and during such periods may have to power cycle my router to get back up to speed.

    I haven't contacted Apple yet. I reset my network settings and power cycled my internet modem. I have pretty good speed (100mbps wired) so I don't know what the issue is.

    Has it ONLY been inconsistent with your iPhone, or has it been inconsistent with all wifi devices you own?

    I know it's a bit of a PITA, but use process of elimination. Also, download the Speedtest app from the app store - this will allow you to check your true internet speed in real time. I have 100mb internet as well. Sometimes I get 175 (!!), other times I'm lucky to get 20.

    Internet speed really is a quirky thing.

    The wifi on my wife's iPhone 6+ has been inconsistent for about a year! I just figured it's so old it will be hit or miss haha.

    AT&T upgraded our home internet a few months ago, and my wifi has always been great on my 7+ (averaged around 80 Mbps) until the past couple of weeks. Just checked it now and got 24. Seems like it got worse around the same time I reset the network connections, which I did to try to improve cellular signal.

    I'm reasonably confident that this is a problem with your wifi and not your phone. Stranger things have happened but consistent wifi (and even internet connection as a whole) is a finicky beast.

    Have you had an opportunity to test your phone in other places with a different wifi network? Friend's house? Starbucks? McDonald's? That could help narrow it down.

    Can't agree more to using the Speedtest app.

    One of the culprits is often how slow your ISP's DNS can be. On one of your systems, try using Google's DNS (8.8.8.8 and 8.8.4.4). See if your performance is much improved - if so, you can change the DNS settings in your WAP/router to use the Google servers instead.

    In case you're IPv6 - the full info :)

    google-public-dns-a.google.com has address 8.8.8.8
    google-public-dns-a.google.com has IPv6 address 2001:4860:4860::8888

    google-public-dns-b.google.com has address 8.8.4.4
    google-public-dns-b.google.com has IPv6 address 2001:4860:4860::8844

    My wifi works good about, oh, 70% of the time. It's the other 30% where it goes so slow or won't connect to a site. I don't really try wifi at other places often. If I do usually it works okay because I just use it for a couple of minutes or something.

    Thanks for the reply, but I have no idea how to mess with the Google DNS stuff. Does that hurt anything?

    What model wireless router do you have? It's probably an old 2.4GHz only router.

    No, but that's why you try it with one of your systems before changing it in the router (to make sure it's a better experience than your ISP's DNS). Even then, I'd likely try it out over a few days...see what you think.

    But, if you aren't comfortable changing the TCP/IP settings on your Mac or Windows system, then you likely shouldn't! :)

    It's painfully obvious at this point that fischersd knows a lot more about networking and stuff than I do...but if your wifi is working correctly 70% of the time and is a little slow 30% of the time, that's basically standard procedure - at least in my house! Lol.

    Maybe we'll both learn something here.

    I'm not sure. Whatever AT&T gave me for Uverse Gigapower.

    Do you have a desktop connect to the same WiFi?
    You could run a Speedtest there whenever you notice it’s having issues in your mobile.
    That could help localize the issue as either isolated to your iPhone of a global issue with your WiFi provider....

    Thanks, but maybe I shouldn't mess with that.

    I have a desktop that's wired to the router.

    Thanks. I'll give it a shot later using its wifi.
