[Q] change CM12 wifi hotspot broadcast channel - Xperia Z1 Compact Q&A, Help & Troubleshooting

Background
I live in the stix and my only source of internet is my 'unlimited' data plan via phone carrier which also 'allows' me to tether.
This gives me about 15meg download on 58-65 ping which is really nice especially as there is no extra charge for the data I use.
Issue
Recently I started getting random 'limited' connectivity.... which of course means no net connection and to fix I discover the 'Default gateway is not available' and the adapter needs resetting. This solves the network connection.... but a complete nightmare if I'm downloading a big file that can't be torrented and I have to start again. I've tried changing from 'Obtain IP address automatically' to manually setting the IP address,subnet mask and default gateway but this random dropout to 'limited' persists.
I installed Vistumbler to check traffic and discover I'm broadcasting on channel 6 which is populated with lots of other traffic (5 other networks near by using channel 6) and figure this may be a potential cause. (someone else disconnecting from channel 6 at shutdown maybe...?... but that's a wild guess) So only way to discover how to stop this happening is by a process of elimination.
Question:
Does anyone know which 3rd party Wi-Fi tethering app will work on Lollipop and can change the broadcast channel number of my wifi hotspot from my Z1c running CM12...?

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] [REQ] Seamless data access

I've had a problem that has been bugging me with my phone for a few months. I have no programming abilities, but was hoping someone here might be able to whip something up.
Whenever network interfaces go down it kills data access for 30-45 seconds. Not usually a huge problem, but I work in a hospital where there is a new router over the same network every 50 yards which knocks out the signal.
I also notice the interfaces switching when I put pandora on in the car. In my driveway I am still pulling from the home router. I lose audio when I the phone switches to 3G then lose it again when it routes to 4G.
My solution: Have a dummy interface that all data is tunneled through. Some service in the background pings all available gateways every X number of packets to monitor which are active. It can then swap between known working interfaces so there is no drop in service.
Problems I'm considering:
1. Power - How much would keeping alive all interfaces and each modem drain the battery?
2. New source IP -- Each time you switch the interface you are connect to a website from a new IP address. Would pandora allow this, it sees it streaming to your account on a.a.a.a and all the sudden you are telling it to stream to b.b.b.b. Same goes if you were logged into your bank account, your logged in and all the sudden their servers see someone choosing links with a different ip address.
I know there are many people on the board much smarter than myself. Could this be done?

[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?

Lollipop - Change in Wifi / LTE behaviour?

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.

Problems to create 5ghz hotspot

Hello one more time team
Here I'm reporting another annoying bug with my device
I have tried many time to create or make a 5ghz hotspot work
My external devices can see others 5ghz network but even when i create it with the RM5S, It is not visible.
I have done a network reset on the phone, check and unchecked the "support 6th generation" option in the tethering options and it just does not work
2.4ghz works fine
I have reported the issue via ticket but I guess will not be solved as my previous tickets
Anyone with the same issue?

some countries do not allow the use of personal 5g wifi tethering. its possible you live in one of these countries? the feature is blocked on the rom if you are in a country that does not allow it.

Hey Patrick
Thanks again for your answer
I read about that limitation in a oneplus forum but I don't really know how to check that.
Actually, i can add something to my issue
While i am reporting the hotspot issue, i must said i am able to share a "connected" wifi using the 5ghz band WHEN (Sorry for the big letters) in use an app called "vpn hotspot"
I dont want to confuse you
I dont need the vpn hotspot app to create a normal hotspot. But the default settings of RM ROM does not let me create the 5ghz connection.
When i connect to a 5ghz router at home, i can "create" another wifi 5ghz network using "vpn hotspot" app (i usually do this cause i need a vpn network for many devices)
The main problem is with mobile data. When i am not at home, the vpn hotspot app does "IS NOT" allowed to modify the system settings for the hotspot created by the rom, it only replicates the original setup and bypass the VPN traffic
So, going back to the original issue, i am not sure if it is a country restriction. I usually live.in Hungary but i am now in poland and i received the device on this last country.
I would even wonder how to create the hotspot using the wifi 6 standard as it should be supported as well.
Thanks for the feedback

sounds like the VPN software you're using is interfering with the creation of the hotspot.
if the 5g hotspot wifi works as intended using the normal hotspot settings on the phone without the VPN, then it would make sense that its the VPN app thats causing the issue.
I can create and use both 2.4g and 5g wifi hotspots, sharing my Mobile network. it works correctly. i do use DNS 66 to block adverts but thats the only VPN type software i use, and its only for black listing adverts and inbedded video adverts on sites.
so test the hotspot settings with the normal phone settings with the VPN off or uninstalled. - if this works correctly. the problem is with your VPN software. you would need to contact support for that app.
some devices do not work with wifi 6 option enabled. turning it off may increase connectivity issues.

Well. I know there was going to be some confusion.
The hotspot does not work with 5ghz even without vpn.
When i use my home wifi, I connect from my phone (no mobile data) to my vpn provider and then with another app, "vpn hotspot" (root required) i can share the vpn traffic to external devices via hotspot. When I do these steps sometimes 5ghz works, and i say sometimes cause I left the "vpn hotspot" wifi setting as default. I might change some network options there but, those options are not available for hotspot within "vpn hotspot" this is why i am blaming the ROM, But maybe you are right and there is some interference between apps. I will try to flush the settings one more time
I have flushed the rules of the vpn hotspot app and tried again. Working fine with and without vpn!
Thanks
I see.
You are trying to filter your wifi connection at home through your phones wifi and share thst connection to other wifi devices.
I dont believe it will work correctly. you're essentially trying to create a wifi repeater.
You're making your wifi chip do 2 things, and its unable to run two streams at the same time.
It state in the Hotspot settings
" Use hotspot to provide internet to other devices through your mobile data"
If you want to connect to your home wifi with your phone, and share thst connection with another device you must use USB tethering.
You risk causing damage to your wifi chip trying to force two connections on it.
using repeater apps, does cause the signal strength to degrade, (bacause you're using the same antenna to receive your home wifi and to create its own wifi. limiting the bandwith and can cause connection issues over time.
the wifi chips in android phone can create a repeating wifi signal, but they're not made to do it. normally as stock android runs when you enable wifi hotspot, it stops the current wifi connecting to create a new wifi access point. using apps to get around that may cause issues and even damage as i stated above. if your wifi chip breaks due to improper use, it will need a warranty return.
