BT - WIFI interfirence
Try this on your Excalibur:
Establish connection with BT headset
Dial voice number
Activate WIFI at the same time
Did you hear any crackling and noise in your BT headset?

i'll try this a bit later when i get the chance, but isn't it common to have some interference if data is transmitting for both since they're both operating on 2.4ghz? also, what headset are you using? bt 1.2 should be better than 1.1

Well, I don't have this problem with TyTn.
I've tried Nokia BH 900 and Jabra JX10 - both 2.0

I'm glad i saw this thread. I'm having the same issue. I cannot stream music to my motorola ht820 bluetooth stereo headset if i use wifi. It just keeps stopping and freaks out on me. I was having issues streaming videos to my dash via wifi and using the headset also. I could not stream 100kbps videos over wifi! I thought the phone just wasn't powerful enough. (although it's not.. I could stream 300kbps videos on my old hp 3615 via wifi fine.)
I just was able to stream a video at 300kbps fine without bluetooth turned on using wifi and it worked fine. Grr!!

BT and wifi both use the same frequency.
I think you shoud try an other channel for the wifi. It may solve your problem.

Wifi how do you set IPs/DNS info?
did i over look something i can't figure out how to set IP, DNS and Subnet for my phone. I've gone to every connection screen did i over look something?

Internet via WiFi - Wireless Access Points Only
I am not subscribing to the data service on my cellular net. I only want to be able to access the net and email when I am in range of my WAP at home/work or at my favorite hot spots. I've got the WiFi settings so that I am connecting to my WAP and can see the SSID when it connects.. I've tried adjusting the settings in the IE options and am at the point where once in a while (1 out of 8 or so ) I can open access one page of a web site.. but can not navigate any further. If I type a different URL in it says locating and loading then times out.... what did I miss???
T-Mobile Dash / Re-ROM-ed to Excaliber.
All other functions seem to be OK.
Thanks, XmP

I've seen this as well. Playing around earlier today, I installed Opera Mini. Opera works fine over wifi or edge. I believe that the issue involves one or more IE bugs involving either the size (fragmentation?) of cache and/or scripts.
Also, Opera Mini isn't a solution (yet) either. It works great once installed and launched from the installer - but has to be uninstaller and reinstalled to work after you exit.
I can't wait for a linux port

I run into this problem all the time at my college and at my home. I turn on my wifi and the phone defaults to the network instead of wifi. I am on cingular with the 8125, I was using I/S PL 1.08 i just updated to cingular rom 2.24.10.1 WWE. I have tried IE, Opera, Mozilla (Minimo) and another i forget the name of. In all I preferred Opera but I feel Mozilla will be the best once the bugs are gone.
Oh yah and when I try and connect to the wifi network at my school they require a redirect to login through bluesocket. That is just too difficult for my little wizard and I rarely get through that system.

External antenna jack on Excaliber/Dash... is it just for GSM? or also WiFi?
Anyone had experience with the external antenna jack on the back of the Dash (under the mirror button)? Just wondering if using this connector would improve performance on WiFi? or is it designed only for GSM reception?
I found a cable which fits the connector perfectly. Thanks for your responses.

Issue solved!
I rebooted my wireless router and everything works great...

Bump!
I'm guessing the absence of answers means that the settings cannot be changed (or may need a reg hack to do so) - I can't find them anywhere either...

so it works for an external wifi as well?

yes, it is possible to change these settings (or at least the IP adress). I have read about it, but can't remeber where. It's possible to chnge it somewhere in the registry, can't be changed directly through settings. If I find it, where I read about it, I will post it here ...

As I remember the external is designed for car holder external antenna, not for WiFi. You may find at most of the GSM mobile back also have this.

This was posted over at howardforums too. What, you didn't search the internet endlessly to find an answer?
Above poster is correct, it's for GSM only. Like I said over at HoFo, unless you're lost in the backwoods, I don't think it's going to help much. Plus, it looks a tad silly!

Thanks for all your responses. Yeah, I posted the question in a couple of forums (the level of expertise varies widely, as you know!).
Reason I asked... we want to be able to access realtime weather conditions while at a remote nature facility on a barrier island here on the West Coast of Florida -- you know, like hurricanes There is a weak WiFi signal from an access point about 1/4 mile away. I simply wanted to establish a stronger link by using an external antenna.
So although it might have looked silly, it was to be a quick fix for instant weather updates (like radar), when needed.

Wifi connection sloooow. For you also?
Hi, with my stock htc s620, establishing a connection to a wifi network that is already saved (home & work), takes around 1 to 2 mins.
What often happens also is that it goes to sleep before even connecting (with me waiting in IE or mail to clic on a favorite or do a send & receive action).
I can't understand this since a nokia n80 will take seconds and it's almost instantaneous on my macbook.
Are there any tricks or software that can accelerate this (unless I'm the only one to have this problem)?

Seems to be a problem of your hardware or a configuration problem. I have energy save mode enabled and usually it takes two or three seconds to connect, sometimes up to ten seconds, if it has extremly low WiFi-Signal.

interesting, I'm going to investigate on the software part first... You really think it could be a hardware issue?
What's sure is that once the connection is established, it's fast and doesn't drop.
BTW, do you mean seconds after the handset is waken up from sleep?
Hum, after looking in my Remove section on my handset, nothing appears, is there some kind of registry cleaner for smartphone?

[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?

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.

Help with my wlan_rx_awake issue N7 4.2.2

I've been trying to narrow down the battery leech on my Nexus 7. Something is keeping it from going into deep sleep; it will spend more than 80% of its time in wlan_rx_awake and 20% in deep sleep and a few others (with screen off and otherwise idle). For example I just rebooted about 2 hours ago and while PowerManagerService is currently the #1 offender since I've actually been using the tablet, for just wlan_rx_wake I've got 32 minutes and a count of 2204. Last night I saw the count at over 8000 and the majority of the time.
I've blown away the obvious suspects - apps that might be waking my device up like facebook or garbage like that. I've done a lot of googling and UTFSE, and have been monitoring BetterBatterySaver, Network Log, and CPU SPY. There are no single processes or appps that seems responsible on the N7 - I'm thinking it's some sort of wireless broadcasts from my d-link 655. Network log shows a lot of UDP packets from 192.168.0.184 to 255.255.255.255, with source ports either 32805 or 32806 and dest port 1234 or 53274. Some research shows 1234 is VLC USP stream and 53274 TCP is "Xsan. Xsan Filesystem Access" from Apple - but I don't find anything about UDP 52374 192.168.0.184 is my Seagate Goflex Home, my network attached storage device - which is also a media server. I don't use the media server component but it apparently can't be disabled (though I've thought of logging into the goflex via the secret ssh interface and killing the minidlna server for troubleshooting purposes[it's running an embedded linux].) I've already disabled UPnP on it and that didn't change anything. I've also gone to the 2 Windows 7 machines that share the wifi and disabled the IP Helper service; something I read somewhere suggesteted that. It also suggested disabling Shell Hardware Detection, but disabling that service disable Windows Image Acquisition, rendering my wifi-attached HP 3050 scanner inoperable. So I had to leave those running. I'm not seeing a lot of packets from that printer so I don't think that's it - I really am suspecting the Goflex Home.
I wish I could output from Network Log. The Goflex home traffic is broadcast in bursts of about ten packets with anywhere from 1 minute to 45 minutes between. That's why this is my suspect but it could be a red herring. Can anyone offer me suggestions on how to proceed? Is there perhaps a sysctl command I can use to tell the device to go into deep sleep quicker? I suppose I could just have wifi turn off when the screen does but I'd rather not, I like the benefit of having everything sync'd and up to date. For now I've installed DS Battery Saver which just intermittently turns on Wifi. Hasn't been long enough to know if that helps.
Thanks for any help!
tl;dr wlan_rx_wake is keeping my device from deep sleep, leeching battery, and I suspect it's my Goflex Home's network broadcasts but I'm not sure.
Edit: Attached BetterBatteryStats output log

Did you try shutting the NAS down for some time, to really see if that's the culprit ?
Also one idea I've seen is disabling IPv6 on Windows clients in Adapter settings, which connect to the network, but this probably isn't the main case here.
Regarding output from Network log, you can enable monitoring in the app, so the log gets recorded to the storage. You can even filter the output before recording, so it's not crowded.

I've got it logging, and filtered right now for just the Goflex IP.
I have rebooted the goflex, but not shut down for a period of time. Since it's only a weekly backup server that's not a bad idea.
I have made some progress. I got root on it and killed the minidnla service as well as the mt-daapd service (the latter provided Itunes [and possibly Bonjour] service I learned). Even with those killed I'm getting the same spurious UDP broadcasts with the same UDP ports. Using netstat on the goflex I found that a service called "locator-server" was opening connections to one of the aforementioned remote ports (didn't note which). I can find very little info on this service in google though. The goflex's core is an Axentra so I'd think more info would be available but not that I could find. Here's what's in the startup script for that service:
# locator: UDP broadcast of HipServ's presence
# description: broadcasts UDP messages to announce presence
I *think* that locator broadcast is just for this garbage Seagate dashboard program which is not necessary for the function of the NAS and is not installed. But I'm not sure. I suppose I need to shut it down and see if I lose functionality.
I guess I before I spend more hours on this I need to answer a basic question: does a series of wireless UDP packets to 255.255.255.255 even keep the N7 in wlan_rx_wake state?
Whatever's doing it is hitting it hard, of 2 hours uptime BetterBattery shows 45 minutes wlan_rx_awake right now with 2nd place going to just 2 minutes of PowerManagerService.
Edit: well I killed locator and not 2 minutes later got another burst of traffic from it, to UDP ports 1234, 53274, from 32775 and 32776. I even did "netstat -cap|grep -e 1234 -e 32775 -e 32776" but got no output. Time to shut it off.
Edit: No longer getting the spurious broadcast packets, but the wlan_rx_awake number continues to grow. All apps look normal - google play, mail, currents.

Hm, maybe try shutting down all devices in your network except the phone and router. That's the easiest route to troubleshooting with so many parameters - exclusion.
If this doesn't help, then you might want to borrow another router and after that it must be the phone configuration. But you'll know where to focus on.
A quick google for udp broadcasting to 255.255.255.255 says it might be the Apples Bonjour service. I presume you have some Apple software on the clients, so you might want to check that out. Try my suggestion above to see if it clears up when only the phone is present on the network and you'll know it's the other clients for sure.

Well I did a sort of test like that today - I took it to work. No issues at all with it going into deep sleep or wlan_rx_wake increasing dramatically. My battery lasted all day even with quite a bit of use.
Using Network Log I can easily see which systems are sending out the 255.255.255.255 packets, next step is to narrow it down as to what IP corresponds to what device. I can't shut all devices down, I have roommates.

With the Goflex NAS shutdown, my network broadcasts have dropped dramatically. At work I can use it off and on all day and still have 80% battery with 5 hours deep sleep. I get home and the battery starts to drop faster, and the wlan_rx_wake counter starts rapidly going up. But Network Log shows only normal things like checking email, no suspicious packets. I don't get it - why is it that at home the wlan_rx_wake counter just goes nuts and my battery shoots downwards -- it's now at 64%, down from 80% when I got home four hours ago, and I haven't even touched it.

Then it's the clients or router, if thats also whats left in the network ;] As i said try to troubleshoot those, talk to roomates to shut them down for couple hours or something.. Maybe its just one particular client, with some kind of broadcasting **** which is waking your device.

Do you happen to know does any packet sent to the broadcast address wake an N7 up from deep sleep?
Also shouldn't they be showing in Network Log? It's like wireshark so it should be showing any packets I receive.

You can also go through some tips in here : http://forum.xda-developers.com/showthread.php?t=2133176
The NetBios part was happening in my home network and I saw those in Network Log app.

Thanks, those are good tips I hadn't stumbled across that thread. I don't think I can disable netbios (I'd have to google how to do that anyway); I do my backups and file storage to a Goflex NAS via Windows networking and my wife I and I share some files between our Windows 7 machines. I also can't turn off Shell Hardware Helper service, as it seems to be needed for my network scanner. I did turn off the other services already "IP Helper" and "Windows Media Sharing Service" with no change. I've already got all systems that I have control over getting a static IP from the DHCP server, though I realize that's not the same as setting a static IP. But if I set a static IP I'll have to disable it when I get to work and re-enable when I get home. If I just spent my time on one network that'd work. Actually though for testing I could do a static I suppose. It's not possible in 4.2.2 to set a static IP on one SSID and DHCP on another is it?
Network Log is really not showing much NetBIOS activity anyway - seems like dhcp requests are the most common broadcasts I'm seeing.
Biggest revelation from that thread was that Network Log doesn't capture all packets! - I'd need to put Shark for Android on my N7 then transfer the file to my desktop and use Wireshark to look through it. Ugh, time consuming but I may have to do. Another thing I can try is disable IPv6 on my N7 but it looks like I need to install Android Firewall to get to that setting, it's not accessible otherwise.
Edit: Changed my DHCP leases from 24 hours to 7 days. I found these interesting checkboxes in my router config page though (Belkin d-655):
Enable DHCP Server: X
DHCP IP Address Range: 192.etc to 192.etc
DHCP Lease Time: 25200 (minutes)
Always broadcast: X (compatibility for some DHCP Clients)
NetBIOS announcement: X
Learn NetBIOS from WAN:
NetBIOS Scope: (optional)
NetBIOS node type :
Broadcast only (use when no WINS servers configured) X
Point-to-Point (no broadcast)
Mixed-mode (Broadcast then Point-to-Point)
Hybrid (Point-to-Point then Broadcast)
Primary WINS IP Address: 0.0.0.0
Secondary WINS IP Address: 0.0.0.0
I wonder what would happen if I turned off those two broadcast options....
I tried changing to hybrid mode, then making 192.168.0.1 (my router) as the first address. All sorts of things went awry then. I could get to the internet despite the Network and Sharing Center showing an X. Also when I tried to browse my network, it said File and Printer Sharing service is turned off, do you want to turn on? I'd hit yes and a second later would do again. I went into the Windows 7 settings and everything regarding sharing had been changed to no. So I turned them back on (I also share a printer from this computers) And I reverted back to broadcast only on the router and now I can browse my local network, but the goflex didn't show up under Network until I went there by hand (\\goflex_home\) in an explorer window. Very odd. Maybe I'll just stop wasting time with this before I break something, and just use DS battery saver at home.

Well, I've not made a little progress, my tablet battery can last overnight now. It still spends many hours in wlan_rx_wake (6 hours) though deep sleep is finally beating it (17 hours). The only significant changes I can think of were disabling "IP Helper" and "Windows Media Sharing" services, and disabling DLNA and mt-daapd on my goflex_home. To do that I had to ssh in, and chkconfig'ing them off didn't work - I had to rename their startup scripts /etc/init.d. I think it was the latter that helped the most as Network Log showed most broadcasts coming from it. I'm still curious if any broadcast traffic on the wlan is enough to trigger the N7 to wake up from deep sleep. CPU Spy shows most cpu time in Deep Sleep now, with the next highest being 340mhz.
Hope this info helps someone else.

[Q] change CM12 wifi hotspot broadcast channel

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...?
