No Mac or IP address - Xperia Z3 Compact Q&A, Help & Troubleshooting

I have tried everything to resolve this issue. Pc companion doesn't work, EE have no clue as their diagnostics doesn't flag a problem with the WiFi. Flashing kitkat 4.4 made no difference. Is there any other firmware that might help? I see lots of people having the same issue but no resolutions yet. I have no warranty so I can't send it for repair.

[Q] Milestone X720 problem with network.

I've purchased a Milestone X720 for my wife, but I found the internal WiFi to work erratically at best.
It seems like it has no problem connecting to Google.com webpage (also it can sync mails and contacts), but when trying to access any other webpages (bbc.co.uk, espn.com, etc.) using the browser, it's always timing out. I know it's not a problem with my WiFi / internal network / router /internet connection, because I can navigate just fine using my HTC Desire or home laptops.
It worked for a while yesterday afternoon, then this morning wasn't able to connect to any website.
The wifi connection is using DHCP, and it shows a correct internal IP address and an excellent signal level. I don't think there's much more things I can tweak in the phone configuration, or isn't there?
Maybe it is a defective phone? Did someone experienced something like this? Should I return it and exchange it for a new one?
I'd appreciate any help.
Alex.
Actually, I've been having problems with my wifi. My wifi will stop working on any webpage at seemingly random intervals (I used to think it was when it went into sleep, but it happens when it's not in sleep now also). Eventually after restarting wifi so many times it'll glitch up and I have to restart the phone.
Providing your phone's stock (as in you haven't rooted it or the like) I'd recommend going to your carrier about the problem.
EDIT: I just checked through the posts on this board and some guy was having another problem with his wifi (different from both of ours though), he suggested getting WifiPowerSavingOff off the market, I'll try it and tell you if it fixes my problem. The only problem is it requires root access, I don't even know if it will fix your problem so you're better off sending the phone back (especially since rooting voids your warrenty). One other thing you could try is just a factory reset, it sounds like a software problem so that might work wonders, you might have to reactivate your phone afterwards though.
Well, thank you for your response.
WiFi was working OK when I came back from work, but is not working now.
The phone is unbranded unlocked, so I'll probably have to talk to the seller.
I tried to see if there was an update from Motorola, but every time I go to the System Updates it says that it is unable to connect to the server, so there's probably no available update for this phone yet.

If it's unlocked OTA updates (updating through the settings) are probably disabled, because installing OTA updates will make you lose root (I'm assuming your phone also is rooted if it was unlocked by the seller). do you know what baseband your using right now? Also, have you installed rom manager or anything that can make nandroid backups?
I might be wrong, but I don't think it's rooted, I think it's just the way it's sold, SIM free and unlocked from factory, not by the seller.
Baseband is 3GSMEPU91A_U_91.07.56I
Well if you wanna double check, just look to see if a superuser permissions app is installed (if you don't find one it's not rooted), I never knew they sold them unlocked (although I'm in the US... so I doubt they do here). All I can say is to try a factory reset then, if that doesn't work then talk to the seller. It sounds like more of a software problem since Google works.
In the end it seems there is some kind of incompatibility between the phone and my WiFi router (a Belkin G). Yesterday I managed to borrow another WiFi router (Netgear) and it works flawlessly when connected to this AP.
I will keep testing during the weekend but I'm pretty sure this was the cause.
Thanks Shiny for your help.
Hi. I picked up a milestone via Ebay two days ago and had similar wi-fi issues. After reading a number of forums I discovered that the problem lay with my router - Siemans Gigaset SE587 (Tiscali). The wireless channel or regulatory domain was set to auto channel 1. I think this confuses the phone so with the help of the router manual I disabled auto and reset it to channel 13.
Wi-fi works flawlessly now and it hasn't affected my other devices. The link below might help.

[Q] Exactly same MAC address on two different HD7 devices

My basically knowledge of networking devices tells me that two different devices should NOT have the same MAC address. However, this happens on my two recently bought HD7 phones.
I didn't notice this at the first time since the network all work on both devices, browsing internet, email, etc.
Then I tried to activate the devices and tried to install apps through marketplace. One of the device works just fine. However, the other has a problem that, it keeps prompting me to setup the account and it keeps failing with "Can't set up your account", error code "8000FFFF" and always stuck at the Country/Region Loading status...
I tried to re-flash the ROM, doesn't work, change the location, doesn't work. I then noticed that both the devices share the exactly same MAC address and this just blows my knowledge foundation of the computer netwoking. After checking the Wi-fi connections on both devices, they are with different IPs (assigned by my router, DHCP). I also checked my router, it shows only one of the devices. The other doesn't appear, however, I can use network on that device. So mysterious!
Now I come to this forum to see if anybody have experienced the same issue before and might share with me some lights.
Thanks,
-jack
Agree that it shouldn't happen. Don't know what version ROM you have but there were versions (I believe some Mangos) that were changing their MACs on every reboot. That has been fixed by the chefs. Maybe you can try rebooting to see if your MAC changes. On the possibility that you have an older ROM you would see the MAC change and thereby fix the problem of identical MACs. If so, you could let it change and then flash one of the fixed ROMs so it won't change again. If not, I suppose you could flash an older ROM with the problem, let the MAC change and then flash a good ROM. Just my non-technical DIY approach. Perhaps a dev has a more elegant solution.

I'm using the latest deepshining v7.7 ROM. I guess this is a new ROM that resolves the changing MAC address issue.
Hi, you can try downgrading rom to nodo which doesn't have static mac address and then rebooting phone and switching back to tango (or mango), this might solve the problem.
My firend have same problem so I formated his HD7 and entered my live account I was able to download stuff from marketplace so what do you think about it he is using deepshining ROM 7.7 with all language

Wifi issue after MM update

Hi guys! Can you help me out! I installed several MM Roms, as i can not connect to certain wifi networks. I installed many of them to troubleshoot my phone. I have no idea why i can not connect, why it stucks. . It stucks at obtaining IP adress. Before i first install the marsmallow on 5.x.x series i was able to connect to any wifi network (obviously if i had the network key), but now i can not connect to my workplace wifi, also at my friend. At home it is all OK. All networks are 2.4ghz. Other then this i can not see 5ghz networks. i saw a solution for that, but most adb drivers are for x86 even if it says its for x64 systems (or either im too noob, buti can not install them on win10). But the main issue, which pisses me off, is the problem with 2.4Ghz networks. Does any of you have any solution for that. Furthermore, have any of you faced this problem before??? Thanks anyway!

Yes, i tried that, thanks. The problem doesnt seem to be the encryption, as its passes through. The issue is with obtaining IP address. Maybe in MM they changed the way that DHCP(IP address obtaining) works. If i can not find a way to change that, i will have to revert back to Lollipop.

Oh! I see... that is a pitty! I'm thinking in advance to Android 6.0, but i hear several issues about it. So, meantime I´ll keep android 5! Hope you finda solution, best regards.
Hi Guys!
Accidently i found the solution for the issue. I share it with you, in case if anyone interested. If you tap 5 or 6 times on the build number, you'll be able to become developer. After this you go to the developer options, then scrolling down, you'll find an option to revert back to Lollipop tipe DHCP. If you tick that, you can connect to any wifi network. (in case if you have the network key) You'll no longer stuck at "obtaining IP address"... Hope that helps

Can't turn on WiFi...WiFi permanently disabled

A couple of weeks ago, I found my Xperia Z unable to turn on wifi and bluetooth, making the phone almost useless. It was under Android 5.1.1, and to latest version.. but I can't say for sure if the OTA update had happened overnight or not.
Like many others, I had Wi-Fi MAC address and Bluetooth address unavailable in Settings/Status.
Both tests in Settings/Diagnostics returned a "Passed" result.
I went to *#*#7378423#*#*:
- in Service info/WLAN MAC addresses, MAC Address 1 was still present (which already made me doubt that it was HW issue)
- in Service tests, the WLAN and Bluetooth tests failed.
In my case, pushing on the Wifi and Bluetooth button had absolutely no effect.
So I started to read forums and posts regarding this issue.
Like others, I tried to repair the phone through Xperia companion (PC). It didn't fix anything and on top of that, I lost all my data. Not a disaster since you can retrieve a lot of things with the google account.
Then I tried a factory reset, for the same result.
Next, I decided to try to downgrade the system, so I unlocked the bootloader and looked for Sony roms to flash.
In most cases, it just failed, yet I managed to downgrade to 4.4 and 5.0.2. Unfortunately, no more result.
So what else to do ....ANY SOULTION ...PLZ
the info in the original helped me a lot to confirm that my xperiaz still knew its wifi mac address, thanks.
In my case a full factory reset from the settings>backup-and-reset option (Andoid 5.02 on xperia z) did the trick. please try that first after backing up your pictures and downloads and other personal files. Also do this with the usb disconnected and allow the booter to scan for wifi networks during boot rather than deferring until later. Finally dont confuse this kind of factory-reboot with a normal power-off reset. I only did this after it was suggested on the sony xperia website - still useful in 2020.

New mac adress after every reboot with Atoto A6

Hi,
is there a way to get always the same mac, because of that my mobile hotspot doesn't connect correctly.
I always have to add the new mac address to trusted devices.
I know a reboot is normally not necessary, but sometimes it happens, but this my cars fault.
Some tips?
Thanks
Frank
Somebody, Anybody?
Damn this is the only thread to show up with this problem when searching. Mine does it too
I emailed atoto they said their aware and working on the issue for the next update.
I guess you could wait or try to root and install a Mac id changer and set it yourself to stay the same?
Hi, this is now solved with the update released yesterday, check out the support site the update is big, so it won't go through the OTA.
