Realme 7 pro (RMX2170) running Android 10 got random wifi mac address feature enabled by default and the only way to disable that is to change individual wifi properties AFTER connecting to the network (per ssid basis). That is a problem for me because our Institute wifi uses PEAP and needs device mac to be registered first on their system. Since my device is not connecting via true device mac (which I registered), I can't connect it to the network. There's no option in developer options as well.
the same by Realme 7 5G (RMX2111) android 11 UI V2.0, i cannot give a fixed MAC address!
I can say to use a fixed address but every joining WLan the last six HEX Numbers were random playing....

I got my HTC Hero on Orange in the UK last week.
I am getting an issue where a normally stable wireless network will be knocked out if i connect the Hero on Wifi.
I know its not the radio - connects fine on WEP secured work network and on the open connection on the train and at McDs
I have done a fair bit of googling and RTFM and basically found lots of router specific issues on Android phones but nothing that looks like the same issue i have encountered except one on the Android community forum where no one has a solution or suggestion i havent already tried.
XDA developers was a great help with unlocking and flashing a ROM to my Trion so i thought i would amend the post i made there and see if i get any more expert opinion on here. Apologies for the length of the post - will post ROM and build numbers if that helps (and someone tells me where to look on the phone!)
Conscious this is a lenghty post (hello all!) but thought as i struggled to find anything it might help others in the same situation if i detail the issues and what i have looked at and hypothesised that i need to try to resolve this - in case anyone else has similar issues.
Netgear DGFV338 ADSL and Ethernet VPN & Firewall router.
Three wireless laptops and Sony Ericsson G900 all connect fine
Laptops run XP Pro, Windows 7 RC and a dual boot Vista/Ubuntu machine
desktops (all on gigabit backbone) run similar mix but only lose internet after router and modem have borked.
I am running this on a 20 MB Virgin connection which is usually faultless (3 years or so uptime not counting upgrades to the modem). Speed or timeout is not an issue - usually get between 12MB and 17MB DL and 700kbps UL
As soon as i connect with the Hero i can use the Wifi but briefly (one web page, start to load Market etc) - basically network detected and WPA-PSK TKIP connected, IP allocated and showing in wireless clients table of router.
I was running restricted MAC access and IP/MAC binding as i have ports open for the 360's and the Wii and want to restrict access to these devices only but removed this as part of the troubleshooting.
Shortly afterwards 20 seconds to 1 minute after connection the wifi drops - all connections lost, laptops lose connections and i lose connection to Virgin. It requires a full reboot of modem and router with the Hero off to recover a connection.
I wiped the router and all the security and all the other pcs etc work fine
then turn on hero - same story. So its not any of my more esoteric and paranoid router settings - i dont think.
Been on the Netgear forums and apart from some issues with the G1 and AES on home routers (mine is the full enterprise kit metal case) i find nada
Troubleshooting to date has narrowed it down to a couple of choices.
I know my router but i am brand new to this phone so some of this is pure guess work. One suggestion was ARP floods from multiple requests from phone getting it blocked by the firewall. Except traffic logs dont support this
Encryption support:
I use WPA PSK TKIP - this is detected as WPA Personal by the Hero but it can connect to router when i use the pass and this setting so i am working on the basis this is supported and correct.
I have read about issues with poor AES support on some routers which are fixed by a firmware update but have the same issue with other devices on AES so would prefer TKIP. So it could be encryption handling - initial connection works but error logging could crash the router if this is not working correctly
Anybody know if the WPA personal listed for connections is TKIP or AES?
I cant find any clear information on this.
Orange DNS or restricted gateway settings:
This appears to be the main symptom - i lose DNS support and therefore access to the internet. Turning off the Hero and reconnecting the laptop gives me access to the router but i need to reboot the modem to get my IP back (dynamic but changes every 12 months or so) the hypothesis is that the Orange connection in this build has the DNS hardcoded to go through their DNS servers which either Orange or Virgin systems dont like and boots my connection off the internet. Bit of a long shot but as i cant seem to find any way to fix static IP or DNS listings it could be the case as i cant switch to OpenDNS as i would to test this otherwise.
Only comes to mind as the first day with the phone (when Orange 3G was not active) i didnt have this problem - wifi on phone and laptop worked fine and both together
Bit of a longshot but the symptoms point to a DNS corruption if it isnt my router treating repeated WPA or DNS requests as a DOS attack. It could be DHCP creating errors but i can bind a MAC to specific IP to override this on the router. It sees the Hero, recognises the MAC and adds it to the restriction whitelist.
I havent checked ARP logging but that theory could pan out as its unlikely DNS would take down the router and modem - ARP or DOS lockdown could.
WiFi Channel
I run channel 11 due to neighbours wifi interference - Wii wont work at all with default channel.
I cant find the default channel information on the Hero but would assume it is 6 like most devices.
this one is strange - if it is the Wifi Channel then seeing the router should be a problem and connection shouldnt happen at all. It seems unusual to allow a connection but then crash the router as it is getting traffic on a different channel.
Could be another side effect of my routers firewall blocking suspicious traffic but seems unlikely.
As you can see a fair amount of things have been tried and i am still getting nowhere.
I need to try the encryption settings - does anyone know what the WPA setting is on the Hero and which encryption is supported/offered as standard?
I need to try changing my router back to channel 6 - does anyone know the default channel or how to change this in the Hero?
I need to try static rather than DHCP (but on the phone as already have tried forcing IP from router) - how do i get to these settings?
I need to try static DNS rather than Dynamic (router proxy of Virgin DNS)
I do have a Linksys WRT54g (three of them - one vanilla, one Sveasoft and one Tomato) which i use for outside events at work so i could swap one of those in but i suspect its a combination of Hero settings and router settings and i would like to get my main router set up (and keep the 8 ports) than swap back to the older WRTs and have to set up my Xbox 360s to get around the issue they have with being on a switch with a different subnet and not connecting to Windows 7 media centre
Basically i have tried most of the things i can try with the access i have on the phone and my knowledge of its default settings. What apps can i try to give me control of the networking and access section?
Otherwise, loving the phone. Better than the reviews and whilst not lightning fast its a damn sight quicker than an overclocked Trion i was running before (which worked fine on the same router and WPA Personal)
I am liking Android, glad to not be locked into the Apple tax/ecosystem and realising that WinMo has a looong way to come; even with the help HTC and xda developers offer to make better use of the hardware.
But i am heavy internet user and i cannot risk running my Hero at home on 3g when i have 500MB cap and a £3 a MB over limit charge with no notice from Orange to say i am near limits.
Any ideas? feedback? similar tales of woe?
Possible solution
Ohkaaay - found advanced settings so that helped! n00b error
Removed all security.
Changed channel to 6
connects
change to channel 11
connects but crashes router
reboot router and modem
change back to channel 6
change security to WPA Personal AES
connects
doesnt crash router
change to channel 11
connects
doesnt crash router
i appear to have a working connection and there is no way i would have made it through this post with the Hero on before i made these changes
weirdly i now have two identical entries in the wireless networks list
one says SSID_name Connected
two says SSID_name WPA Personal
remove remembered networks
Hero autodetects my SSID_name
sign in with AES password
two listings in wifi list again, same as before.
So it looks like WPA TKIP doesnt work on my router with Hero
AES does.
Channel 6 works with no security
Channel 11 doesnt
BUT... enable AES and Channel 11 works.
Guess the Channel 6 signal issue interferes with the TKIP or something
But i can report that on Netgear router WPA Personal AES works ok, which apparently on the pre-Cupcake G1 was a known issue.
Apologies to post and then reply to my own post but this might help someone
I can confirm your findings regarding WPA + TKIP vs WPA2 + AES.
I was running WPA + TKIP on a Linksys WRT54GX and experienced major connectivity issues with my Hero (although is did not crash the router). Did not experience this problem with my iPhone 3G.
Changed configuration to WPA2 + AES and Hero does now work without any issues.
I know this:
A. Is fairly obvious
and
B. Is not particularly helpful to you
However - if any device (regardless of whether it is buggy or not) is crashing your router, the router clearly has buggy firmware itself and is at fault. Router firmware should be robust to the unexpected, especially on wifi as this could be prone to denial of service attacks from anyone happening to be walking by. A router that is crashed by an attempted client connecting is a bad sign.
My personal advice would be to change to a decent standalone router. I use a Buffalo WHR-G54S flashed with Tomato firmware v1.21.8005 (with a seperate linksys Adsl2+ modem to provide internet). It is working flawlessly for me in WPA + TKIP/AES with no issues.
Just got a Wifi/3G Flyer today, running Gingerbread 2.3.3. and software version 1.56.720.2. I have a WPA2-PSK secured Belkin wifi router at home. Currently, it has 2 laptops and 2 phones (BB & Galaxy S2) connected without any problems.
My Flyer refuses to recognize the router, but it shows up my neighbor's similar WPA2 secured SSIDs instead - (so presumably the wifi hardware is working).
I have already tried/checked the following:
Router's SSID is not hidden.
Router supports push button WPS - does not work with the Flyer though it configured my Samsung Galaxy S2 perfectly fast.
Rebooted router.
Changed router security to none, WEP 64 bit and WEP 128 bit.
Manually entered settings - it just says my network is 'not in range' despite my sitting right next to it.
My router settings are:
Authentication - WPA-PSK + WPA2-PSK
Algorithm - AES
Wireless channel - auto.
Wireless mode - b/g/n all supported.
Is there a fix for this that doesn't involve rooting the device?
Update: Used the software update to get it to 2.3.4 and software version 2.27.720.1, and it still is showing up every goddamn wifi network in the vicinity other than my own one
change your channel from Auto to channel 10 or 11. Normally this will not affect your other devices. It seems that the Flyer is quite sensitive for this kind of 'problems'
Holy quack, that worked!
Thank you so much! I set the channel to 11, after which it started detecting the network, but would connect and instant disconnect. A reboot fixed it for good!
All,
I just recently got my S3 (T-Mobile) on opening day 21Jun12 however could not get my wifi to work properly at home. It would say "connected" on my S3 but no internet and wifi calling. In addition, when I tried to "enable" my wifi calling, I would get a REG99 error. Tech support narrowed this error to an address update on my profile (911 address info) which was updated but the problem still existed. I troubleshooted with my router and saw no problems on that end due to the fact that 8 other devices connected fine. After looking carefully at IP addresses, I noticed my S3 persistently tried to connect with an IP of 192.168.100.16 where all my other devices had an IP that started with 192.168.1.(xxx). Check to see if your S3 defaults to a conflicting IP or IP that your Router does not accept (My router accepted standard IPs from 192.168.1.1 to 192.168.1.254). Before you do the steps below, reference your Router Configuration and check your starting and ending IP addresses, Gateway IP, DNS and Alternate DNS.
Now for the fix:
If you're S3 is connected to your home wifi but no internet, wifi calling, etc.
1) Simply goto Settings
2) Click on Wifi to get to the your wi-fi networks list
3) Press AND HOLD on the connected network (The one that says connected) and a window will pop up
4) Select modify network config.
5) highlight advanced options
6) Change IP settings (dropdown) to static
7) Enter a new IP address that your router accepts (ex. 192.168.1.10). Like mentioned above, my router takes 1-256 for the last number set. Be careful to not select an IP address that's already being used. You can easily see what IPs are used in your router configuration setup (something like attached devices).
8) Make sure your gateway is similar to your router config (usually 192.168.1.1)
9) Network prefix length - I left this alone at 24
10) DNS 1 and DNS 2 can be also found in your Router Config setup. (DNS 2 is usually your alternate DNS).
11) Click save and voila (You may want to turn wifi on and off on your S3 to recycle)
After 3 tech support calls with no resolution and researching this for the last 2 weeks, I found the answer to my problems. I can understand how annoying this problem could be for some people out there so I decided to register with XDA and post this for you all.
Hope this works for some of you. Enjoy!

Sounds like an issue with the phone's DHCP client.
However afaik T-Mobile sells the US Galaxy S3, not thn international i9300 what this forum is about.

Got an s3 today from radioshack. I had an S2 before. I went home and tried to connect to wifi like I normally do. I use WPA2 Personal TKIP+AES encryption with MAC filtering enabled so only devices I know about can connect on my WiFi (friends were jerks and I needed a way to control who gets on.) Anyway, I added the Mac address to the list of trusted devices and tried to connect after putting in the WiFi password. I was unable to connect and the error message it gives is "authentication error occurred" "incorrect password". A bit of trouble shooting later, because i knew the password was right. I decided to disable the MAC filtering for a moment to see if I could connect. I was able to connect, but as soon as i enabled the MAC filtering it disconnected with the same error.
My Question is, is there a way to fix this problem? Without rooting and without disabling MAC filter permanently
Things I have tried:
changing the frequency of the router tried channel 1-11 (phone only works on channel 6 with filter disabled)
changing the authentication type
removing re adding the mac address
rebooting the router
rebooting the phone
standing in-front of the router with the phone pass-phrase input
dialing *#0011# and turning off power saving on the WiFi
I assume you've double checked the mac address is correct? Ensured lower case for a-f chars? Oddly it does seem as if its an incorrect mac address.
Does your router show macs of connected devices if you turn filtering off? If so, copy / paste from there?

just wanted to update and let you guys know whats going on. I found out what the problem was, and I am currently taking steps to fix it. So the mac filtering is the problem for sure. I did not input anything wrong. I found out that because the S2 and the S3 are similar the mac address of both phones cant be added at the same time or neither device can connect to the network. I decided to root the S2 and change the Mac address so that both devices should be able to connect.
Better than rooting the S3 since i dont have insurance on it.
anyway hope this update helps someone else who has the same problem.
Hi. I own a pocophone F1 which recently got the android 10 update which come with the randomised Mac address setting. At first I thought by activating the said setting I had get a different Mac address each time I connect to a X network but it seems like a set Mac address is associated with X network even when I forget it and reconnect. I wonder if there is a way to customised the random Mac address.
Thank you
