iPhone 10 slowest performer on network

iPhone 10 slowest performer on network

My XFinity Wi-Fi has worked without a flaw since day 1.  However recently, some friends have moved in. We share our Wi-Fi with friends and family. The new users all use Apple iPhone 10. 

Internet service on my network devices works with great performance.  With exception to the three new iPhones. We have some dead areas in the garage where the speeds go down below10mb. The gateway device does just under 400mb throughout the house. The Apple iPhone 10 is extremely slow even in the same room as the gateway.

Can I do anything reasonable to remedy this problem? I have two extenders on the network already. Suggestions?

Try to use the 5g wifi band its alot faster then the 2.4g band. You can change it on your iPhone in settings.

My first suspects would be the extenders. Having used the iPhone X previously (have an 11 Pro Max now), those phones have pretty powerful antennae, and I susepct they're picking up signals from the extenders in addition to the gateway, causing slowdowns.

I'd suggest turning off the extenders temporarily and see if those phones improve their speed.

For that to work, the router or access point would have to broadcast the 5Ghz on a separate SSID in order to connect to it separately. Plus, given the existence of dead spots in the house, using a separate 5Ghz SSID isn't recommended, as the band doesn't penetrate through obstacles as welll as the 2.4 Ghz band. 

 

Besides, even if the affected phones were connected to the 2.4 Ghz band, both the iPhone X and the Comcast gateway support 802.11 AC, which allows the 2.4 GHz band to hit up to 450 or even 600 Mbps. Clearly something else is going on here.

@darkangelic 2.4g band doesnt support wifi ac, only 5g does

 Then why does the Wiki page have this chart that  clearly shows 2.4 GHz support?

Re: iPhone 10 slowest performer on network

@darkangelic I have the new Xb6 gateway, when I go to the admin page under wifi 2.4g where you can set the wifi bands to use, ac is not a option, it's only a option under 5g, I am going by that
