Lollipop - Change in Wifi / LTE behaviour? - Nexus 7 (2013) Q&A

I did the OTA update to 5.0.2 a couple of weeks ago on my Nexus 7 2013 LTE.
One change in network behaviour is annoying but I'm wondering if there is a setting I am missing.
I have a WD Passport Wireless and I carry my music around on it. It acts as wireless hotspot and a DNLA media server - running Twonky - and until now I have used Bubble UPNP to stream music. Since 5.0.2 the WiFi will fail to get/ask for a DHCP IP and continue to use the 4G connection while showing a "!" on the WiFi.
If I remove the WiFi profile and re-add then it works - continues to show the "!" for bad internet connection but does get an IP and streams OK - while, as a bonus I still get Internet via the 4G link. As soon as I come off the private WiFi, e.g. when I get to home or work and turn the Passport off, next time the Nexus will again not get an IP for the WiFi connection.
The lack of IP is via the WiFi -> Advanced menu and it shows the MAC but under IP Address: "Unavailable"
I have tried this when underground with no 4G coverage and it seems to then work. So, it seems to be too clever in (not) moving off the 4G.
I have tried a static IP and it doesn't work.
I noticed a toggle for "Aggressive WiFi to mobile handover" in the developer options but neither setting makes much difference
My 4.4.2 Samsung Note 2 continues to work fine, so it's not the WD hotspot
All stock, un-rooted with just dev menus enabled.
Anyone got any suggestions / ideas?

* I am now trying a full factory reset, just in case - as I didn't when I got the OTA and it feels sluggish anyhow.

XDA IIs Wifi and lockups

Does anyone have a problem with their wifi locking up their xda iis? I have bought a linksys router and am getting frequent lockups when using wifi. I am using the shipped O2 rom, thanks
I have no problem at all with Netgear router. Try changing the connection speed setting in the router to the "b" mode only. Hopefully this can solve your problem.
No problems here either I'm afraid. I'm using a Draytek Vigor 2600VG at home and at work there are two of us with XDA IIs using a Linksys BEFDSR41W wireless router and no problems there either.
Sorry! :-(
Try a hard reset (gulp!) and see if you still have problems (Without anything else installed that might be inteferring) otherwise might be a faulty unit perhaps.

I second what xanth said, I had the problem where wifi would not turn on, so I hard reset and installed each software back individually the problem was Calligrapher 7.3 did not like being in Storage or Storage Card only in Main memory (go figure)

I use the XDA IIs on a variety of wireless networks and experience problems with an alarming regularity. The most annoying is the fact that the top bar seems to loose functionality, when using wireless!!
I will actually add that I do seem to have problem with the "range" of WiFi.
I need to do more testing, but it doesn't seem to be more than 20m or so before have communication issues/timing out :-( Will have to find out what our walls are made of!!!
I have problems connecting sometimes. I regularly use three routers, Draytek, Buffalo and Belkin. The only time that it locks up is when using skype. The skype problem is a known issue with no cure.

I am having a problem where my Siemens SX66 will loose connection to my Microsoft MN700 wireless AP on occasion. -It simply appears as if the Wifi radio shuts itself off.
Weird.....
Wifi has never worked for me. It simply doesn't work in the way nature intended.
The main problem (as far as I can tell) seems to be that it cannot get DNS or IP configuration settings from my router (Belkin 7630) automatically.
It can connect to my wireless network without any hassle, but that's about it. If I enter DNS and IP settings manually it works fine. But this is unworkable if you want to connect to another wireless network.
If I can't sort this out by next week I'm going to sell the unit on eBay. It's been nothing but a pain since I mistakenly bought it in December.
Wifi is a nightmare on this device! I'm going back to Nokia.
I am going to do a hard reset and test to see if i still get any freezes. Anyone know of any software i can use to backup my text messages?

Hi guys,
Haven't had too many issues with WiFi over here - standard O2 Asia ROM (with the BT 3500 update).
I'm running a Netgear WG602 @ home with 64bit WEP and a Dlink AP2100 @ work with WPA-PSK. No connectivity problems at either location, both DHCP. It does however take a few minutes to connect, but this is on the odd occasion.
The only frustrating thing with the WiFi is that I have to soft-reset often to turn Wi-Fi on - any ideas? Hopefully O2 will fix this in the next ROM. Other than that, I've had the Nokia 9500, P900/800 and this is by far the best device for the power user.
Just me 2c!
Cheers

Wifi is on all the time on my device, sometimes when I switch the device on while within range of an AP it does not connect. Often switching wifi off and then onn again causes it to connect. If this does not work then I can often go into the network dialogue section, and see the network marked as 'availble' but not connected (why it sometimes does not auto connect I dont know). Tapping connect usually cures. If that does not work then I too need to soft reset.
I hope like you that they fix this cause its damned anoying. I will be interested to see what the Benq P50 is like when its released. I shall get one from expansys to test and ship it back within the 7 days.

As for those having problems with specific access points. It is not nessesarily the fault of the blue angel. It seems to me that none of the manufacturers of wireless kit understand the term 'standard' they all seem to have their own take on it, which is why kit from different manufacturers refuses to talk to each other. I am of the opinion that they do it in purpose to lock you into using their client cards with their AP's !!
Try it with some non Belkin kit and see what happens.
Nigel
Well i tried a hard reset and didnt install any apps and tried connecting to wifi again and still got a lockup and loss of connectivity. Im going to swap the router for another make and see what happens
Swapped my linksys router for a D-Link and so far no problems after 2 days. so looks like my problem was my router.

XDA IIi and wifi
I just bought one of these and can't get it connected. I have a netgear wg602 access point. When I finally figured out how to set the IP manually (the 02 xda tech support said it can't be done - maybe they're right ;-)
I now have it saying it's connected, with right IP address. My DNS and gateway are set up for the wireless adapter in network adapters. The signal is average. The XDA says wifi is connected. The access point even says it's authenticated and associated - same as my other stations.
Only problem is, internet explorer doesn't find any web pages - says "The page you are looking for cannot be found" (works fine through GPRS)
Also, terminal services times out trying to connect to an internal IP address (to eliminate DNS as a problem)
So, anyone know how I troubleshoot network problems - it looks like a TCP/IP issue? Can't find ping or arp etc. I've also tried an IP address that I know works on the network.
thanks for any help

Hi
For ping, ipconfig and stuff, head to http://www.cam.com/windowsce.html
I have had multiple issues trying to get wifi working reliably. It still fails now, but there are a few tricks to get it working again. Most of my wifi issues have been due to regular use of three AP's [email protected] and [email protected] along with GPRS and VPN.
To start with I suggest setting all the ****e in connections (internet and home network to 'My ISP' then goto your wifi setup, network adapters, and tell it that the wireless card connects to the internet. Now, tap ok, and goto tools, network cards, tap the active connection (it must already be connected) and ensure that its set to internet.
Next soft reset the thing, and wait for it to connect to yr wifi. Now, use the ipconfig tool and ping tool from the above site to check that all is OK. Check that its got the default gateway right and a sensible LAN IP.
I have found on occasion that I can be connected via wifi, but that the device is still trying to talk using an old IP allocated by gprs which means nothing to my lan! IPconfig will show if all is OK.
Whoever wrote the whole of the networking system (and its terrible gui's) on windows mobile wants shooting. I usually have 2 VPN profiles setup under my work network. If I leave it set to that, and use wifi from my lan to connect to the internet all is fine. However if I try and access a local server, the damned thing starts trying to connect a vpn (it aint inteligent enough to work out that the IP I asked it to connect to is local).
I have been trying to find a setting for all this networking rubbish that allows me to do *everything* without reconfiguring each time - to no avail.
Another thing to note is that you cant send/receive MMS messages while wifi is connected (more stupidity), it tries to connect to the MMS server using the wifi connection, and the telco blocks it cause it wants to charge you for sending MMS over GPRS. Only solution is to disconnect wifi, send MMS then reconnect wifi!!!

No problems with WiFi for me
Hmm I'm using an O2 Asia Rom as well.. and my wifi manager seems to automatically create "settings" for each AP it detects and I seem to have no problems connecting at all... been using WiFi around my house since the first day i got it..
i am using a Linksys Wireless 802.11b router..
btw I am new here.. finally able to register!
How's everybody doing?
Cannot turn off IEEE 802.1x
Has anyone had problems unchecking the 'IEEE 802.1x netwrok access control' checkbox???
I uncheck it, but then when I go back to the screen (click on the connection | then select 802.1x tab at the bottom) it has checked itself again!
The XDA IIs does not save the setting - it just keeps re checking itself 02 help have been no use - they sent me an instruction manual and it even says in one of the step 'uncheck IEEE check box'
Im am using a netgear wirelesss router and have also tried on a d-link
Sugestions - is anyone else having this problem??

[Q] Wireless tethering via bluetooth

I've got an EVO running CM6 stable with android-wireless-tether (pre7). I am able to pair/connect to my home PC by setting up a bluetooth PAN in Windows 7. I right click on my device, choose "Connect > Access Point" and it says "Connection Successful". The only thing I get now is "Identifying..." until I am stuck with the good ol' 169.xx... IP address.
I checked the log for the wireless tether app, and it shows:
Enabling NAT rules... done
Enabling IP forwarding... done
Tethering now running... done
error: SIOCSIFFLAGS (Cannot assign requested address)
I've done a little research on the error and tried a few suggestions (rebuild binary/config files, changing the default LAN IP in awt settings) to no avail.
I also tried disabling WiFi and just attempting to share the 3G connection which still isn't working out (same error). Can anyone help me out with this one? I've also tried awt pre8 with the same results.
I had same setup and problem. Started the supper user app and quit app. Powered down phone restarted phone. After restart WiFi tether worked fine. Don't know why .
Sent from my PC36100 using XDA App
Just turn on wireless teather and the go to access conections fine androidap and connect to that. Why do you have to use blue tooth am I missing something? Wireless teather is in the settings with CM6 so you dont need an extra app for teather?
Thanks for the suggestions. I tried opening/closing SU app and rebooting, got the same result.
The reason why I am doing it this way is because I have a PC with only a network card (not WiFi). It's about 30/40 ft. from my router. Rather than buying a wireless card or some cable, I'm connecting via bluetooth and sharing my phones WiFi connection.
I understand if I had a WiFi adapter I could just use the built in Hotspot feature, but if I had WiFi, I would rather connect directly to the router.
I'm definitely interested in this too. At work, we have a no-wireless router policy, and I don't really feel like firing it up and have a guy holding a Fluke wireless network analyzer come and find me.
Bluetooth is alright for what I need. Seems to almost be a kernel issue or something. Worked *perfectly* with my N1, even with pre8. The EVO with CM6 stable isnt working. Just as a note, the wifi portion works correctly.
Actually let me rephrase : The bluetooth section does work, I believe there might be an issue related to the dnsmasq dhcp server not being able to serve IPs. The 'Upload' section of the information panel changes, the Green Download section stays 0.00. The client never receives an IP address, and thats about it.
Logcat didnt really show me much of anything critical error-wise, I'm really hoping that I can downgrade/upgrade a kernel in order to support whatever hardware changes there were between the N1 and the EVO.
I checked the wireless router wifi mode, and it no longer works either. 'Started with errors' is what I get now when in the wifi mode. The built-android wireless tether works fine, but I either wish I could hide the ESSID or have a bluetooth option available.
It *seems* related to the kernel, but logcat doesnt mention anything about not being able to load a module, and the wifi-tether app doesnt have a txt log, or does it?

Bt Home Hub 2 Problems

Hey
I've got some severe wifi problems with the BT infinity Home Hub 2.0:
1. Sometimes I cannot connect to the hub and the phone cannot get passed "obtaining ip address"
2. On rare occasions I can connect to the hub but no data is transferred and to make matters worse it takes down the wifi network for others (Other devices remain connected but no data is transferred) To get things working again I have to reset the hub!
If I try connecting to BT Fon or BT Openzone on my network the same problems occur. (Other BT broadband users will understand what I'm talking about there)
What I've tried to fix the issues:
I've tried setting a manual ip address with no luck
I've tried a full reset of the hub
Changed the wifi channel of the hub
Turned on best performance in wifi settings on the One X
I've tried a variety of roms and am currently on Viper
I experience these issues when connecting to other BT Home Hubs and other random hotspots. But at the same time I have no issues issues connecting to other wifi hotspots such as hotel ones and public hotspots.
At the moment at home I've got an old voyager 2100 bridged to the hub and I can connect through that with no problems, but as you can understand I don't really want two routers running at the same time when it shouldn't be necessary.
If anybody has any suggestions it would be greatly appreciated!
Thanks :cyclops:

Just noticed you have the infinity version, which I assume is totally different.
Sorry about that!
(however, I'm stuck on sub 8mb (2mb, ish) in the country, I'd put up with dodgy wifi for your connection )

It's pretty much identical but I've had the same issues on other normal home hub 2s
I had the same problem whereby every time my One X connected to my Home Hub, it would cause the network to become unresponsive for all connected devices! I eventually found that changing my hub settings from 802.11 b/g/n to just 802.11 b/g did the trick.
Go here: 192.168.1.254
then: Settings --> Advanced Settings --> Wireless --> Wireless interface type.

Thanks! I'll give this a go when I get home, I wonder what the underlining issue is here that's causing all of these problems
i don't think its the phone, id blame the router, mine does similar sometimes, works after a reboot of the router though
Hi,
I encountered this issue just recently. I have a Galaxy S3 and a HomeHub2 with Infinity. I tried setting a manual IP address, rebooting router and phone, changing wifi channel etc, but none of that worked. I later noticed that the dhcp table on the router was full of expired leases for the same device. I clicked the "refresh" button on the HH2's dhcp page and it refreshed showing a list of different mac address - weird - but this time showng them with an "andriod" prefix. I manually deleted a few of the expired entries - one at a time (pita) and that seemed to fix it, i.e. I was able to reconnect and get an IP address assigned on my S3 again. I've since selected the option to "always use this ip address" on the dhcp table entry details page (just click one of the items in the list to view). I guess there must be a bug/conflict/glitch between andriod and the hh2's dhcp service which perhaps prevents expired ip address assignments from being dropped and reused. I have a few other devices that are wireless and use dhcp (ps3, iphones, ipad, ipod touch, wii, samsung smart tv, wifi printer, microwave, fridge... ok i'm kidding about those last two , and none of those have multiple expired sessions.
Hope this helps someone get round the problem.
Jeremy
PS: Great noob vid.
Funny this is here. I had this exact issue its frikking irritating. I went through the hassle of unlocking the hub to work on talk talk...I had my nexus then and it flew..I know the nexus is like that though lol. So got the x was a nightmare on WiFi.coverage wise also in the kitchen..it went below a bar. So changed to b and g only. Works okay but still is slow ans doesn't do well. Annoying seeing the hub is capable of n

I'm having the exact same problem but with the homehub 3, I was convinced it was a faulty router and have been pestering bt for a new one. I realized it was the phone whenever the same problem happened at the father in laws house (he has a hh3 also). I have been using cyanogenmod for a a few months and this prob only occoured when I started using mike1986's Rom... Maybe someone should tell him
I'm having issues with my One X and my HH3 , it's only started since i went to jellybean. It was fine before now when my HOX is conneced to the router all wireless devices (Ipad and laptops-win7/ubuntu) will drop out and back in of connection. Sometimes the router will drop it's broadband connection then come straight back up.
It's driving me mad.

[TIP] Wifi connected but no internet connection!

At some points in your life, one of your Android devices connect to a wifi router, but can't connect to the internet. However, your computer, laptop or iPad will connect to that same wifi and use the internet just fine. I've looked everywhere on the internet for solutions, some of them are:
+ Turn off and on both modem and wifi router
+ Factory reset wifi router
+ Battery pull your phone, wait 30s and put it back
+ Reflash stock or custom ROM
+ Change DHCP IP setting to Static
+ Disable security (WEP, WPA) on wifi router
+ Check DNS server, gateway IP address for correctness
Fortunately, I stumbled upon this old thread last night -> http://forum.xda-developers.com/showthread.php?t=1371794
It helped fix the internet connection temporarily, turning off and on wifi on phone caused the issue to repeat.
In summary, he found out the correct MAC address for gateway was mismatched with the one on his phone. Even though the gateway IP address is correct (example: default gateway IP 192.168.1.1)
Upon further investigations, I found out my Wifi ROUTER has the same IP address with my MODEM (192.168.1.1) This IP conflict causes the phone to recognized the WIFI ROUTER's MAC address as the gateway's MAC address. This problem mostly occurs on Android phone, not computer (I'm no tech savvy so I have no idea why)
Simple fix: Go to wifi router setting page, change the IP address on wifi router to different number (other than default 192.168.1.1), and the problem should be fixed.
Please help spread the words to fellow Android lovers, I'm sure a lot of us have struggled with this problem :laugh:
I'm one guy who is desperately looking for a solution to this.
Unfortunately the solution you gave didn't work.
Hi
i have a problem with wifi. it remains connected but loses internet access randomly. i found this solution:
"In the wifi networks, select the network you want and select ‘Forget network’
Turn off the wifi
kill all the apps with your task manager
Turn on the wifi again
Connect to the network
Check the internet connectivity
If still the problem exist, switch off the phone and redo the above steps"
it solves the problem, but it happens again after some minutes. actually, i also installed an app named "wifi fixer" which does the above process automatically. when the program is active, it turns the wifi off and on every 2-3 minutes. and the phone has internet access when the program tuns the wifi on.
any idea?

2 years after the last reply I am having the same problem. My wife and kids all have internet access on their phones, tablets, desktop and laptops all from the same modem router yet I am unable to use the internet on my Galaxy S2 mobile phone even though my phone says connected to Wi-Fi Network Netgear 06.
The Mac address solution provided isn't applicable to my situation as my Mac address on my mobile is different to my modem router Mac address.
Any other solution?

[Q] Wi Fi Connectivity

Hi all,
Lost info for my original account, so I made a new one.
Straight out of the box my HTC One has not been able to connect to my router. It gives me the message that it's avoiding a poor internet connection although under the connections it says the signal strength is excellent. My laptop connects just fine. My Razr HD connects just fine, but interestingly my wife's galaxy S3 will not connect either. It gives her the same message.
I've tried changing the bandwidth from auto to 2.4 to 5. I've tried forgetting the network. I've tried static internet connection with IP address 192.168.0.15 and also 10.0.0.11 I enabled the DLNA, there is no useable option to clear cache or clear data and last of all I did a factory reset.
None of these worked. DLNA and the static internet connection have allowed me to connect, but it's not really connected. I'm not sure what's happening. It says connected with excellent signal strength, but nothing connects. No internet, no netflix, no nothing.
I think it might be something to do with the router itself, but I don't think I'll be able to get any information from netgear's people. It's not broken (other devices connect just fine) but these newer smartphones seem to have a problem with it.
Neatgear N300. Also, I tried WPS connection as well. No Dice.
Thanks
Update-I've found a -similar- issue in this forum regarding specific bandwidth connectivity issues for dual band routers. One of the suggestions was to update the firmware. I haven't been able to do this successfully. Still trying.
Update 2-Tried to connect to Safeway WiFi today. No luck. It goes to the sign in page and it's just blank. At home it says the page is unavailable. At safeway it's just blank...
*bump* No help at all?
