Galaxy S23 Ultra wireless always 'connects without internet' to my Wifi

[FreeKnight]

I've played around with a number of settings on my router, but before I try a full reset as a last result (and sadly needing to resync all my google home stuff), has anyone run into this?

My S23 Ultra connects to wifi without difficulties, either with static or DHCP IP and the default MAC address or set to 'Phone' Mac. It maybe works for an hour but always eventually goes back to 'connected without internet'. It's annoying enough I generally just turn the wireless on the phone off entirely.

Most other devices seem to work, though my google doorbell does seem to disconnect periodically.

Debating if the reset is worth it, and if it doesn't solve it if my aging router might need replacement.

Router is an ASUS RT-AC3100, in 'Wireless router mode'. Wireless is set up as 'Dual-Band Smart Connect' with the smart connect enabled. Authentication is WPA2. WAN was set to automatic IP, but should I also try static?

Networking is my least savvy part of tech ownership so some suggestions to start troubleshooting are appreciated. I've never cared enough to look into it a lot.

I wouldn't touch Smart connect or DHCP reservation by MAC address unless you really know what you're doing.

Honestly though? ASUS router. Hated mine as soon as I got it, replaced it quick. It would overheat and start dropping connections, especially on the 5Ghz band. Maybe trying turning the transmit power on 5ghz down, move as many devices as you can to 2.4ghz, and try Just your phone or other essential mobile devices using the 5ghz.

It's been solid for years, generally worked really well, but the last few months it seems it's been twitchy. I'll look at the transmit power though thanks. There's only 4 items on the 5ghz band so it shouldn't be saturated (laptop, phone, google home and the work laptop which isn't normally connected)

If you factory reset the ASUS, I don't see why you'd have to re-do any of your Google Home devices. Just make sure you set the SSID & Password back to what it was.

Do you have any ISP-provided WiFi functionality that you could compare to? That would help to rule out the phone as being the culprit.

Ive been having similar issue with by ISP Bell with the gigahub with my s23 ultra, i did find a way to fix this by going in the router and disabling Wi-fi 6E, that was causing the issue for me, works normal on Wifi 6.

Some devices are not great with mixed frequencies. Nintendo Wii for example cannot connect to a 2.4+5 band it has to be 2.4 only.

If you running a 2.4/5/6 combo or something else it might give you the best results to actually separate the frequencies out. 2.4ghz for just the Google devices, and 5 or 5/6ghz without the 2m4 included.

Sometimes devices just don't always handle combination SSIDs very well. Especially if signal strength is even partly questionable in any area.

Setting a 2.4ghz onky band for the wii and the other IoT devices has improved a lot of random disconnects I was having with some devices.

I had done something similar years ago, but it kind of broke the connectivity between the google home devices, or maybe the home devices on the 2.4 vs 5ghz didn't reconginize each other after. I can't remember the exact details, but ended up having to re-pair everything after the reset (thought I maybe I changed dual band vs separate 2.4/5, it's been years.)

Mine only goes to Wifi 5 aka AC so it probably isn't that, but thanks for the suggestion.

I think I'll reset and give that a try. IIRC I had some headaches with devices working together between the 2.4/5ghz, but at this point I'm probably not losing out on anything by going back to 2.4/5 split. I'll post back if it works. Thanks for the input Izerous.

Antenna boost strength is also something to double check. At one point I accidently had 2.4Ghz set to max power and 5Ghz set to min power. Caused my phone to drop down to wifi 4 speeds depending on where I was in the house.

100% agreed, and good advice to everyone: IoT devices are all on 2.4ghz, because most (if not all) don't really need continuous huge bandwidth. Ex: Echo devices, smart appliances, security cameras (unless they're 4k ones) and similar don't really need speed beyond 802.11n on 2.4Ghz. So I save my 5Ghz band for my mobile devices (phone, tablet, etc) and full-time streaming devices (fire TV stick, HTPCs, etc). Gaming devices are wired though, always, and I'll never change that haha

Can't comment on the Wii needing 2.4ghz though, don't have one

There isn't a lot of point in getting one online anymore unless your looking to software mod it. The process is easier if it is online.

Getting a dreamcast online was more difficult but atleast a few online servers still exist.
