FTTP installed with good speed but a lag when using iPhone apps like safari.

Hi everyone, I have recently had FTTP installed (500mbps download and 70mbps upload).

The sky broadband router was terrible and upstairs in the back bedroom I was only receieving 3mbps. So i've now turned off the Sky Wifi and purchased a TP-Link Deco XE75 Mesh System, which I use in Access Point mode. The broadband now reaches further, although still not great for gaming, I seem to get bad lag.

What is strange though is I can be sat 3 meters away from the router, open Safari on iPhone and search something on Google and it can take 15-20 seconds to action / respond. If I switch off Wi-Fi on my phone and use mobile data, the results appear immediately. Same when I go to do a speed test, it can take awhile to connect, but when it does it's 400-500mbps.

Is there a reason for this lag? It's really frustrating when it happens whilst trying to use Google or social media apps.

Does anyone have any ideas on how I can rectify this and how I could improve my gaming experience without having to trial an ethernet cable through the house? Maybe I could update some settings on the sky router / TP Link Deco XE75? I never experienced this when I had Sky Broadband FTTC. Makes me wish i'd not upgraded 😔

Thanks in advance

When you use the TP-Link it usually has 2 wireless bands 2.4Ghz & 5Ghz to eliminate almost all lag choose the 5Ghz band by usually splitting the SSID into two one for 2.4Ghz & one for 5Ghz, and then try connecting only with the 5Ghz band if in range.

If the games console will only connect to the 2.4Ghz which has a greater range you will run into a terrible latency issue. The only way to solve this is to move the router closer to the console and that will need a wired connection, unfortunately.

For competitive gaming, it is always wise to use an ethernet cable...
