W806 Alps (Aka K18) MAC wifi issue - Other SmartWatches

Hi all,
Is there anyone having this weird issue?
It looks like every time the wifi gets disconnected or disabled (or the phone is switched off) the MAC address of the wifi CHANGES!
Which for me, since my router is open but access is limited to MACs allowed to connect, is a pain
This is what I noticed just in the past few attempts to connect to my router
1ST 00:08:22:B8:18:FD
2ND 00:08:22:9E:6F:01
3RD 00:08:22:50:BF:B8
4TH 00:08:22:52:60:BB
Any fix and/or workaround?
Thank you

X10 & Netgear DG834v5 Wifi Connection Problems - Solution

Hello all,
I love my X10, but the frustration with getting it to connect to my Netgear DG834 router was getting to me, so I dedicated an afternoon to working out a solution and I've found one that works for me, so I hope it'll work for you too.
Summary of problem
--------------------
The phone will connect to the Router once, and once only. Any attempt to re-connect to the wifi will result in the phone disconnecting, scanning again, then discinnecting until the user gives up. Nothing will cause the phone to reconnect (telling it to forget the connection for example). The only surefire way to reconnect is to reboot the router each time - not ideal.
Manually adding a Static IP also doesn't work - which is weird as that is how I've solved it, see below.
Scale of problem
----------------
The problem seems to be with the router and not necessarily the phone as it appears to be on a wide range of phones (Hero, Droid, Touch HD etc.). Seeing at the DG834 is the most popular router in the world, and Android is growing all the time, there are a large number of people affected.
However Iphone and Symbian phones appear to be unaffected.
Reason for the problem
-----------------------
Currently unknown, but appears to be something to do with the handshaking procedure when a device asks the router for an address (DHCP) - though as to what I don't know.
Solution
--------
1) Download an app called WiFiStatic from the App Market. WiFiStatic takes each DHCP assigned IP address and stores it in a small database to be re-applied whenever you are back in range of the same Router again. It is not an ideal solution as you may have to re-scan and re-assign if you visit a busy hotspot, but this is a two press function, so it's not that onerous.
2) Turn off your Router. Make sure the WiFi on your phone is off too.
3) With the router off, clear your Remembered WiFi connections (or at the very least the Netgear connection). Once that's done, turn the Router on again and wait until it is full back up again.
4) When the Router is fully operational again, turn on your wifi on the phone and let is scan for and connect to the Netgear Router. You may need to tell it to connect from the Wireless Settings menu on the phone.
5) The phone should now connect to the Router successfully. If it doesn't, repeat the above procedure.
6) With the phone connected to the router, fire up WiFiStatic. Check Auto Switch and Show Visual Prompt if they are not already selected, then Tap Add configuration at the bottom of the screen.
7) The IP address and other settings assigned by your router should be displayed at the top of the screen, at the bottom should be the name of your router and its MAC address. If not then tap Menu > Generate to populate the form.
8)Tap Menu > Done when everything is ok.
That's it. Now when you move into range of your Netgear, you should get connected, though it does take a bit longer than normal (the Router still wants to assign an address first before accepting the static IP). You can speed this up by changing the Device table on the router to always keep the Phone's static IP open.
This shouldn't work as all my other attempts with Static IP failed, but I've had five days now of instant connection to WiFi at home, so something has been freed up.
i can not tell you how seeing this post was like finding bin ladin in the white house. Prob would have found him twice trying to solve this WIFI problem. And the strange thing is this is the 1st phone i have had that there are so few posts about it...is everyone on that icrack? scary. cheers to you...
Thank you for posting this.
I tried this with my and it seems it doesn't make a difference for me. I still can only connect once to the router and for me to connect again i have to restart the router again. Am i missing something?
Problem is when I connect for the first time at home it works then when i leave to the office i use the wifi there and never have any problems there but when i get back home it doesn't work. Do you guys switch the wifi off manually when you are not using it?
one thing that is almost always overlooked is updating the router's firmware. this usually solves a number of issues. I dont know about netgear but it's worth a try to update

That was one of the first thing i tried....it seems i have the latest firmware.
Is this an issue for a lot of people then? Ive one of these routers and never had an issue connecting any phones to it. Had 3 nokias and 3 different android phones, currently on the x10, and they all connected fine everytime.
i have some troubles in x10i wifi connection and holp someone helps me~
------------------------------
im chinese, my x10i have had the lastest firmware but the phone cant connect the AP which set the channel is "13". but i used it long before and suddy just one day i find it dosnt work~ it cant scan(and find) the AP anymore !
then i have tried and config the router in another wifi channel(just like 1,8,11..) and the phone can scan and refind the AP.
i have tried to reload the phone's default setting,but it dont work(in channel 13)ToT
---------------------------
someone tell me why? and someone give me some suggest?
in china , lots of router's wifi channel are using "13" by default(factory setting);so, if my x10i cant works in that channel means i couldnt find the "opend APs" which in the public place(like KFC~~)
THX to help~

Thank you! I have spent three days trying to get my phone to re-connect to a DG834v5.
Your solution has worked! I had gone as far as reserving an IP address on the router and linked it to the MAC of the phone... no dice. The phone would connect once and then never again until the router was reset. Really irritating because I have two PPPoe connections running through the router with a routing table that has to be re-loaded via telnet every time the router is reset. I was considering a new phone or a new router.
HI,
I have near the same problem.
But I found out that when I remove on the access point the hidden function ( SID ) then it works perfect.
so that is a bug in the ROM of the X10, I have the R2b026.
At the moment everone can see my Access Point but I can live with that solution.
Worked for me! Many many thanks this had been infuriating me...
Same problem here - never had an issue with any other router, so I blame Netgear...
Let's just hope this works - it's been driving me crazy for the past 5 days...
Neh, hasn't worked for me....
Stupid freakin' Netgear...
works on the HD2 aswell. Thanks alot!
Not just Netgear, maybe Android

I am having the same issue on my HD2 Android 2.3.4, connecting to a D-Link DIR-635. If I use Static IP, everything is fine...
WORKS! I can't believe it, finally i can disconnect and connect without having to reset my router everytime. BIG thanks man!
alright, it worked fine for the first 5-6 hours. then it went back to not connecting without rebooting the router. this problem happens only with my home router, at work i can connect fine, as well as in other places.
any thoughts or solutions? i mean it did work in the beginning, then why did it stop? shall i change my router?
P.S.: i noticed that every time i connect to my home router i get the same IP address and all the stats are the same.

[UPDATE]Official Nexus one Wifi issue thread(every N1 owner should read)

Sorry I know this problem probably has been brought up many times. But here I just want to make a total one and collect all the feedbacks from N1 users regarding to the wifi sleep issue with N1.
Let's just make it simple: Every N1 owner PLEASE DO test out the wifi connection when your phone goes to sleep as there are MANY people suffering from this problem all over the world. Especially the later buyers since February this year, almost every phone is potential to this problem.
######################################################
Diagnosis:
1. Set the wifi sleep setting to "never" in the wifi advanced setting menu.
2. Turn on Last.fm app(or Pandora, but Last.fm is most effective and responsive one to test it out), leave the phone on wifi and turn off the phone screen or let it goes to sleep.
3. The symptom is the app will stop streaming shortly afterwards(with Pandora stops maybe after one song, for which I suggest everyone test it for at least 15 minutes). Also most likely you will stop getting any email notification or anything requires data connection. And you might not be able to ping your phone or the ping responses VERY slow as well.
######################################################
######################################################
Background:
This problem was recorded from earliest almost 6,7 months ago and has affected both AT&T and T-Mobile versions(with reports of the same issue on other versions sold outside US). So far, it's suspected that the problem mostly likely lies in the lower level architecture of the phone(either software or hardware) because the problem still exists even after people has replaced the stock ROM with the custom ROM. Another proof is that people get problem with brand new phone and also the replacement phone. Another note is the problem has been found both before FROYO update and after. At this moment, there's no official fix(some Google employee blatantly brushed the issue away and asked N1 users to get over it, check out the link below for original conversation) for this issue except a work around thanks to wifi fixer app developer.
######################################################
This issue is often times neglected by N1 users because usually people don't use the phone on wifi all the time or they simply switch between 3g and wifi. But for people who use wifi a lot or use VOIP, it could be a real deal breaker.
So here I just hope everybody could test your phone out and see if you have this issue or not. Please report how your result turns out in this thread. Also, for further and more detailed discussion and cases, please check this out:
http://www.google.com/support/forum...52&hl=en&fid=01a47ff5b0a92d5200048be07b6cb5c1
You are more than welcome to add your experience to the discussion above so hopefully it can wake google up.
####################################################
UPDATE:
So Broadcom just released a wifi driver fix several days ago which may solve this issue. According to the record, phones with non-zero MAC address suffer from problem.
The driver has been incorporated into the latest Cyanogenmod(either RC or nightly build). People are reporting it fixes the problem while in some other cases, the problem still exists even after the fix, even for people who's MAC address starts with 00.
Last.fm works fine with the screen off here, always has done. I even turned off mobile data to be sure it's not switching over to that.
This is with the wifi set to sleep with the screen off (ie. the default setting).
i've been using wifi fixer and since i installed it, i haven't had a single wifi disconnect on my home network(it seems to be a network dependent issue as i never have issues on other networks)

yeah, the point here is that many phones have the wifi sleep policy issue(doesn't work).
Indeed, however mine does, so this thread will need both sides of the argument
No problems on my Nexus One, running latest CM 6 nightly build.
I bought it couple months ago from eBay, so I'm not sure which shipment it is from.
Only issue I'm having after upgrading to Froyo is that my phone won't connect to my home network by itself when in range.
I have to go into Wifi Buddy and manually connect. This never happened on 2.1, but magically started after the FRF50 update, and never fixed itself in the next couple of builds.

I have always had this same issue! Maybe its something to do with my home wifi? I am yet to test it on froyo.
I am mostly connected to wifi with no sleep issue.
I have kind of the same issue at home, I recently replaced my wireless router, I never had problems connecting to the old one it would just stop broadcasting constantly but my N1 would always connect automatically. With the new router my N1 keeps saying the connection is disabled and I have to connect manually. This never happens at work, it always connect automatically so it seems to have something to do with the router settings but I have no idea what.
No problems here. Last.FM works fine for me on WiFi when screen is off. I also get notifications. Running FroYo rooted with locked bootloader

i am having the same problem, when i go out of range from my wireless and then back in range, the n1 just says scanning and never re-connects.
that said, using a channel lower than 11 on my router did seem to help with the sleep issue.

sorta, i never had the issue on any network besides my home one
I've also been having the disconnect problem with my N1. Maybe it would help if people whose sleep policy is actually working could post what wifi router/AP/whatever they are using. Also, if possible the first for identifiers of their MAC address. I read on one of the Google posts someone with a MAC address starting with 38:E7 having problems. The MAC for my phone is the same. For what it's worth I'm using a D-Link DIR-655 router and a Speedtouch 716 v5 WL and am experiencing the disconnect on both.
I've had the issue with 2 N1 tested on 3 different routers. I've read that it is related to the low power mode the N1 uses while sleeping not playing nice with routers. Not all N1 show the problem, apparently only the most recent ones. I've called google support and was told google knows about the issue and is working on it, but I am a bit cynical and I'll believe it when I see a fix.
Wifi-fixer fixed my problem only after I disabled Sipdroid which was interfering with it.
Mac adress: 38:E7: D8
I'll post my router model later when I get home.

It's weird because most of the time I don't have this problem. My WiFi stays connected all night long to WiFi. But once in a while it does disconnect and switch to 3g. I think its certain routers, because I didn't have this problem for first 3 months on my old router, now it happens with my new router.
My phone never has trouble reconnecting back to WiFi. Everyday when I come home from work, as I walk up my driveway the phone has already automatically connected to WiFi. I've made sure about this one since I read this problem all over.
I bought my Nexus One directly from Google when it came out for AT&T. It certainly has the wifi issue and it is very annoying. My expectation is that the phone jump on my wifi network when in range as all of my other phones have done. Instead I have to manually engage the phone to get on wifi. SUCKS!
this is the biggest problem for me with my n1.
although the wifi does stay awake, it slows right down..
if i ping my phone, the response time increases when the phone is asleep, but doesnt time out.
if i ftp a file from my laptop to my phone, the speed drops from 1mb/sec to 100kbps/sec when the phone is asleep.
i have found the app "fix my wifi" solves the problem of waking the phone after a few hours of sleep and finding the wifi has failed. if only there was a way of getting the speed to stay the same.

[Q] Reboot router to connect to Wifi

I'm puzzled by the behavior of my phone. For probably a week at a time, I go to work, connect to a WIFI there, then come home, connect to a WIFI there. No problems at all.
Then it seems like after a week or so of 'being good' sometimes I'll wake up the phone and it will see the network, but will not connect to it, asks for passphrase repeatedly (WPA2-AES Cisco E3000 router) but just will not connect. I have found no way to trigger the phone to reconnect (and I refuse to do another hard reset because that is no solution at all).
The simple fix is to reboot the router. Presto, the phone will connect almost immediately.
I am willing to accept that maybe something is wrong with my router, although I have 3 laptops and a couple of IP cameras, and an Xbox that connect wirelessly all the time, and I never ever see this refusal to connect on any of those devices, and my wife's Blackberry will also connect whenever. So I'm thinking its my phone.
So for the experts out there, what is it about rebooting the router that fixes the problem?
I only recently learned how to get into the manufacturer's special app, so I'm going to pay attention to my IP address next time I have an issue, and see if it actually changes when I reboot after this problem occurs again.
Where does one discover how and what can be tweaked in the secret app? I'm cautious but not afraid....hey, I've edited the windows registry countless times on my PC and never toasted the OS yet! Does that count for something?
Add: I had this happen once at my work WIFI, using an ancient DLink router using WEP. At the time, I was trying out a bluetooth headset (Plantronics Backbeat), which worked, albeit, after I was done listening to the podcast, be darned if I didn't get into this refusal to connect thing, and unbeknownst to me, I was using the 3G data connection for what I thought was a wifi broadcast. That sucked 175 megs that day! I was a bit pissed about that. I have not used the Bluetooth since then.
Rebooting my router at work fixed the problem but I hate doing that, because I've got other equipment on that network that likes to be permanently connected.
the same happened to a frined of mine: interoperability issues with that model of router and the phone, changed the router and after everything worked perfectly, that sucks, but it is
Had a similar problem, and simply could not pinpoint the cause. Solution? I resetted my router to factory settings, and started to change all the settings from scratch to my desired settings. One thing that helped solve my problem was that I changed the default IP address used by the router (in my case, 192.168.0.1) as well as the IP range to something more ... random. Also, I limited the number of allowed IPs to 10 rather than the default 100...That helped. Never got a disconnect or problem connecting again. I had the same thing happen on my mother's iPhone and my brother's Galaxy S, and this solved it.

Major WiFi connection issue

Hi
I've had a search in the forums but haven't seen any other posts re. this but wondered if anyone had any ideas?!
Basically I'm having problems connecting to some networks with my Tab 10.1 (stock, updated OTA to the latest TouchWiz UX last week).
I first had a problem last week when I took the device into work - there's an 802.1x EAP network there but it wouldn't even show up in the network list. My SGS2 connects to it without an issue.
Then when I got home tonight (after happily using it at my parents' house during the day) I found it wouldn't connect to my home WiFi (hidden SSID, WPA2). It had connected to this network fine in the past, but now was just sitting showing it as 'not in range' network. At first I thought it might be a router issue (it used to be a little flaky), but then I saw that my iPod and SGS2 were both connecting and working on it without a hitch.
I couldn't see the network at all in WiFi Analyzer (similarly to at work), although it was showing my neighbours' WiFi networks fine. I tried deleting the saved entry and telling the router to broadcast the SSID but it still wouldn't work.
I then put on my WiFi hotspot on my SGS2 (also a previously remembered connection) and it worked absolutely fine!
Does anyone have any ideas where to go next apart from doing a full reset? (which although not the end of the world would be quite a pain).
Thanks for any suggestions/tips!
OK, bit the bullet and restore my device to factory settings - it STILL can't see my home WiFi, despite my SGS2, laptop and iPod all connecting to it fine. It is however showing up two networks belonging to neighbours and also my SGS2 if I put it in WiFi hotspot mode!
Any suggestions folks??
Sounds like a route issue, did you reboot the router? Is the router on a channel below 12?
Hi thanks for the reply!
I actually just spotted a post at http://www.thegalaxytabforum.com/index.php?/topic/5511-my-wifi-no-longer-works/ with the same issue.
It looks like Samsung have mucked something up when they made the Touchwiz UX update - it now blocks WiFi channels 12 upwards, when the old stock Honeycomb firmware didn't do this. I'd moved my router onto 13 to reduce congestion and I guess the work one must be on 12/13 too.
I can see from the table at http://en.wikipedia.org/wiki/List_of_WLAN_channels that 12/13 are only allowed under low-power conditions in the USA, but this isn't the case elsewhere so they shouldn't have locked it down outside of the USA.
This also happend to me

As I had setup an additional router in my house (with assigned a high numbered -or so i thought- fixed IP address) for some reason my main router tryied unseccesfully to assign the same IP to my SGT as the router. This had obviously conflicts and could not log in.
Went into the router eliminated the fixed IP address and voilá! it got working again, all IP a dinamic!!

S8 Internet connection may not be available issue

Just got the S8 and I have 3 Wi-Fi access points at home to cover the whole house. My S8 has been registered with the passwords for all of the APs but it continually rejects the connections with an exclamation mark after the WiFi icon having connected and then shown a message that the Internet connection may not be available. The Internet connection is available as other devices are connected and using it perfectly. If I switch the Wi-Fi on and off and reboot the S8 the issue corrects itself but I should not have to go through that nonsense every time I come home and want to use my Wi-Fi. I have explored the advanced options on the connection settings and they appear to be quite limited (DHCP Etc). Is there some way to solve this issue? I have no problem with other android devices connecting to the same hotspots. Any ideas that might lead to a solution would be appreciated.

I had this problem when i first got my s8 from vodafone but when i got this latest update it's been good no issues with internet anymore.
I have this problem as well with my S8 from Verizon. Worked flawlessly for a week and them today I get this error. Very frustrating. I know the SMG955U from Verizon is already unlocked but is there any way to put the International ROM on the phone seeing that the Verizon and the International are the same?
I've tried all the resets etc and the WiFi connects but I get the 'Internet connection may not be available' message.
Update 27/04/2017
Thanks for the reply. My S8 developed some interesting issues including the switching on of 'do not disturb' mode intermittently and along with the Wi-Fi issue the mobile data was failing in areas where a full 4G signal was present. Rebooting, resetting etc did not resolve the issue and I returned the phone to CPW for advice. The staff at the Glasgow store wasted no time and exchanged it on the spot after some negotiation with their technical service centre. Full marks to CPW for the prompt service and I can report that all of the previous issues have now been resolved with the replacement handset. I thought it worthwhile to post this information so that others who experience similar issues may be able to get a similar resolution.
Poor WIFI performance
I also have issues with the wifi of the phone, /i will get the terminal replace some time today or next week.
1. WIFI keeps disconnecting, actually it's flapping connct&disconnect for 5-10 min until it finally connects, on this matter I have seen on the acces point that it tried to allocate an ip from an unknown without asking DHCP server for an IP renew it actually tries to alocate itself the last known ip, and clearly disconnects because of lack of internet access, this happens normally as power saving mode is on, disabeling power saving and assigning a static ip on the phone seems to resolve the issue.
2. poor wifi signal... no fix for this thus far
- i have 580Mbps speed connection on my S5 and only 120-240Mbps on my S8, steaming not working and connection in general very bad, time ots and stuf, although I position myself at 10cm away from the wifi router antenas i only get 540Mbps signal, although I have an AC1750 router , s5 gets 840 in the same spot... I think the modem(that is part of the Exynos chipset) does not work wekll with Atheros based AP´s , I have an Archer C7 with 2.4ghz QCA9558 chipset capable of 450 Mbps theoretical speed, but only uses 2 antenas as s8 only has 2 from my knowledge and reaches a max of 140Mbps(should of connected at 300Mbps at 10cm in theory ) with the s8 and QCA9880-BR4A on the 5ghz side of things with a theoretical speed of 1300Mbps should work at 866 with the S8 because of the 2 antenas of the S8.
phone changed 90% of problems fixed
Hello, just got my phone replaced, tha new unit has way better wifi signal considering I hace atheros router and the phone has broadcom 43xx chipset... worth considerign changing to a broadcom router...
Hi,
I have found a solution to this problem.
1. GO to wifi settings
2. Forget the wifi network
3. CONNECT AGAIN BUT BEFORE CONNECTING GO TO ADVANCED OPTIONS AND CHOOSE STATIC INSTEAD OF AUtOMATIC. Enter in the ip address etc and connect.( It requires to be entered manually) Problem will be solved.

Hi,
I have found a solution to this problem.
1. GO to wifi settings
2. Forget the wifi network
3. CONNECT AGAIN BUT BEFORE CONNECTING GO TO ADVANCED OPTIONS AND CHOOSE STATIC INSTEAD OF AUtOMATIC. Enter in the ip address etc and connect. Problem will be solved.
@Saurav913 doesn't work your tip,but my wifi drop too much especially in stanby (set it on always option) and till I wake up my phone i don't have wifi again with router Vodafone revolution..
Change the DNS...
Hi there..
I had just the same problem with s8 plus and s7 edge(after updating to android 7.0), it kept saying "internet may not be available", I changed the DNS to 8.8.8.8 and tue problem solved. Go to SETTINGS》WIFI》SSID》MANGE NETWORK》change the IP SETTINGS to STATIC》then change the DNS1 to 8.8.8.8 hit save and you are good to go.
Sorry if there are any mistakes. I am new to XDA and not good in english.

Just got the S8 and I have 3 Wi-Fi access points at home to cover the whole house. My S8 has been registered with the passwords for all of the APs but it continually rejects the connections with an exclamation mark after the WiFi icon having connected and then shown a message that the Internet connection may not be available. The Internet connection is available as other devices are connected and using it perfectly. If I switch the Wi-Fi on and off and reboot the S8 the issue corrects itself but I should not have to go through that nonsense every time I come home and want to use my Wi-Fi.

I have same problem and it is very annoying. I got 2 S8 plus and both have the problem.
There are 3 WIFI Router that covers my house. I have problems saying internet might not be available every time I connect. This is very annoying. Other Phones in the house like Iphone do not have the problem.
What I noticed is that the IP range of my router is:
192.168.1.1
But my S8 says he is connected but the IP is
192.168.0.100
Anyone have same problem?
Thanks!

I found a quick work around on how to fix this temporarily until Samsung issues a patch.
just turn off 5ghz SSID broadcasting and you should be ok for now.
here is a quick how to video i made on just in case.

I'm having a very similar problem with my home WiFi and my Verizon S8+ I bought from Samsung's website. I've tried switching from DHCP to static and entering all my info. No luck. I've also switched my dns1 to 8.8.8.8 and dns2 to 8.8.4.4, and my WiFi router is set to 2.4ghz only. No success in resolving the issue. Currently my phone will show the "internet may not be available" with the added exclaimation point for a few minutes when first connected, then the exclaimation goes away and I'll have regular full speed internet for around 25-45 seconds before it goes back to a non-internet state. Any suggestions?
Try changing in your router the security setting. If your using WPA2 AES/TKIP, change to just WPA2 TKIP and see if this works for you...
I was having the same exact issue for months. I changed to TKIP only and have been rock solid ever since. No more ! at all... I'm gonna switch to just AES today and see how that works.
Changed to WPA2-AES and within the hour had ! back and no internet. Went back to TKIP and rock solid again. Looks like a possible bug with AES to me. Sticking with wpa2-tkip setting for now.
I'm having this same exact issue.
Anyone who knows what to look for to fix this, what info or files do you need from me? I'm at the end of my tether with this ****
I am having the exact same issue on my galaxy tab s2, even on the replacement. Due to the being such an intermittent problem, it wouldn't do it when Samsung support checked it out...
This happens on both 2.4 ghz and 5 ghz frequency for me. I've tried downloading a wifi fixer, I've reset network settings, and turned off nearby device scanning. I've also tried doing what a forum suggested by changing the ip settings from dhcp to static but it wouldn't connect to wifi at all. Not sure what else to try...
I read that it may be due to nougat 7.0 software. I was suggested by Samsung to first put the tablet on safe mode (this disables third party apps, and would reveil if an app was causing the problem) but the problem still persists. Also did a hard reset on the first tablet I had but it still done the same problem...
I always thought that this was a is problem in 7.0, and was addressed in 7.1. Hopefully, when the next major update comes out, this issue will be resolved.
Oh come on Samsung!
It's been 4 months since the first post and still no solution.
And it's a basic wifi connection!
Internet may not be available! = Samsung may not be available
Heya all. First post I guess
Edit: Gah it was the second. I have to controll myself better and not spam.
So I had the same problem and tried more or less all.
My "solution" was to disable the firewall on the router which means some settings/security there was triggered. My guess is that it's the "Smart Network connection" that trigger it if the phone have both poor Wi-Fi and 4G. It then jumps back and forward = firewall detect strange behaviour and block. That's why there are so many strange "fix" related to the router - hidden network - no security - disable 5Ghz and so on.
Can someone please test asap as I have a plan But if it's not this to test
