    Hi guys,

    So I got the Note 9 during the pre-order time with Tmobile. I traded in my Note 4. The first couple days, the phone worked fine through 2.4 ghz wifi. But then due to the signal congestion in the area, i think, i had to unplug and replug the modem+router once or twice a day in order to make the wifi works. When it was on 2.4 ghz, i don't remember if my Note 9 got affected at all, i always had connection but the rest of the family devices did. So i decided to turn on the 5ghz and turn off 2.4ghz. Oddly, now the rest of the family, 5-6 apple drvices, smart tv, mac book pro and a samsung tab 4 have not had any issues at all with the internet. But my Note 9 started to act weird, sometimes there will be the '!' next to the wifi signal indicator and the phone loses the connection while other 5-6 devices are connected just fine. I have only found 2 ways to temp fix it: turn wifi on/off and forget network then enter the password again. This is annoying. I have network reset the phone several times but no luck. I am trying to understand if there is something todo with the phone settings itself or from the router. My Note 4 never had anything like this. What are your thoughts on this?

    lot to take in....

    off the top of my head, id say its the router. if you have a lot of devices on 5ghz, there could be some QoS settings on the router that could be causing issues. you may have mac address filtering going on in the router, or any number of things.

    if you have reset more than once and still get the issue AND you are able to connect to other wifi networks, id say its a router issue.

    I had the same problem with my Note 9. Went into my router settings and changed my wifi channel to manual and set it to channel 153. Been problem free for weeks.

    I tend to agree with @marctronixx If you have to reset your router that often that's typically an indicator the router is either not very capable (dated or a low-cost model) or it's configured improperly.
    What kind of router to you have? Is it an ISP-supplied modem/router unit or do you have your own third-party router? What model is it?
