One UI 7 wifi issue

[Isaiah0723]

After installing one UI 7.0. I have had a lot of issues with slow wifi, whether that be loading browser pages, apps, in game loading connecting to servers etc, download updates for smart devices. It has all failed or not working at all. Unless I use my data. I have reset my network settings and my router etc all the obvious stuff. Definitely an issue only when I use my wifi which has never happened before.

I have looked everywhere to disable IGMP snooping and I have absolutely no clue how to do this. I've went to my router settings and saw absolutely nothing related to it or related terms after looking for about an hour. I'm at my wits end with this issue.

If it's not in the router settings contact your ISP. I had to contact them cuz my router didn't have it either

I learned something new today through all of this. check it out... I guess google owns ATT and T mobile.... lol. So, if you ever have problems you can now skip the tri-men and middle man. maybe this info will serve you well if you need it, later on. you helped me. Thanks so much.

"snooping" is a weird way to phrase it, isnt it? when i found out i didnt like that at all lol. eh its it talk. it searches constantly for channels.

It's on default security settings for me, medium I think. Why say that randomly tho?

I noticed my wifi speeds topped out at about 20Mbps down, 100Mbps up on both S22U & S24, both updated to OneUI7. I run my own firewall/router, so I have tools to diagnose & differentiate between speeds from ISP modem to router and router to device (wired/wireless). Wireless speeds on other Wifi6E capable laptop was topping at 800Mbps, which is what I would expect of my Samsung phones. This appears to be a software/firmware problem on the Samsung devices that needs correction. My wife & I intentionally have Hi-Speed wifi for work, so we have to resort to USB to Ethernet adapters for certain workloads until Samsung resolves this problem. While one user noted IGMP snooping turned off on their router fixed the issue for them, that sounds like a temporary fix and not an actual long-term solution. I have submitted a Feedback report to Samsung and hope they push a patch through within the month. 800Mbps --> 20Mbps is pretty rough.
