[Q] JellyBean WiFi signal - Desire HD Q&A, Help & Troubleshooting

Hi all.
So this may be a silly question but I've had a search around and can't seem to find anything similar to my query.
For me, the WiFi signal on all jelly bean roms is considerably weaker than what I get on ICS roms for GB, regardless of the kernel or radio. I am wondering if this is just me or do others experience this too? I there any fix or solution that I've missed?
Any help much appreciated Long live the mighty XDA.

i noticed that too but the only thing you can do is play with your WiFi channel on the router end; use WiFi analyzer from market and walk around your place to see which channel is the best without too much interference from neighbouring signal, then change your WiFi router channel to suit and remember the chosen WiFi channel uses 3 channels at once with the center channel being the one connected to (i.e if your router runs at channel 6, it will also use up a bit of 5 and 7) so choose the clearest channel without too much overlap.
additionally if you have land line wireless phones operating on the 2.4Ghz range, it can interfere as common WiFi routers runs in the 2.4ghz unless you have a 5GHz setup.

[Q] Can't Connect to 5 GHz Wifi Network

Can't connect to my new router's 5 GHz band. It's an Asus RT-N66U. The SSID is visible, but signing in doesn't connect. 2.4 channel works fine, although not that fast. Any help would be appreciated.
EDIT: Resolved - switched to a lower channel.

I used inSSIDer to find the best channel, and I unchecked "avoid poor connections" and "use wifi optimization" in my phone's advanced settings. Also, I found the suggestion that solved my particular problem at smallnetbuilder.com, which has absurdly knowledgeable members who write some great stuff. For example, this article is about competing for bandwidth, which is a concern of mine because I live in an apartment building.
Here is the forum dedicated to the RT-AC66U.

Nexus 7 (2013) Slow Wi-Fi Home Network WPA2 Problems

Hi everyone,
I have my Nexus 7 connected to an verizon actiontec router. I am getting terrible wifi with WPA2 security enables. Loading websites takes forever and youtube constantly gives network error. I changed the encryption to WEP and its not disconnecting as much but I would prefer to run WPA2.
Anyone have any suggestions on what is causing the lag and disconnects? 2 laptops and 2 android phones no issues.
Try switching to 802.11g. The N7 is quite flaky in 802.11n mode with a lot of routers.
If you are using WEP, you are in effect forcing 802.11g mode, since 802.11n requires WPA2.

Thanks for the reply tni,
Is this a hardware issue or a software issue? Could hardwiring and IP number and switching back to WPA2 possibly fix the issue?

Driver and/or firmware. The Nexus 4, which has pretty much the same Wifi hardware, also has quite a few complaints about Wifi issues.

It's highly unlikely that a fixed IP will make a difference.
Not sure if that came across, but you can use WPA2 with 802.11g (you need to configure that at the router).
Well I changed the router over to WPA2 and then in the advance preferences set it to 'Legacy Mode' to support only 802.11bg and the tablet seems to not be having many hang ups even with youtube. I'll post back if anything changes. Thanks and hopefully this helps a lot of people out there.
I'm using N7 2013 with two different routers,
Both with WPA2, and 802.11n.
No problems at all.
Well, I just did a heck of a lot of work on the IEEE 802.11 protocol suite. I am in no way an expert, but I picked up a bunch of interesting factoids.
- In the 802.11n protocol implementation, all devices must have 802.11n supported NICs. This includes all the clients, not just router. If you have even a single device that is doing legacy 802.11b/g while all the other client NICs are doing 802.11n, then the router will not do 802.11n for any device. Yes, all or nothing deal and the router does not show it. I used Wireshark to confirm this situation exists by drilling down a ton of 802.11 data frames. Despite the router staying set in the drop down menu to 802.11n, under the hood, all the devices dropped to 802.11g.
- Even worse, I know I have clients and router NICs that all support 802.11n, yet I get dropped into the 802.11g protocol. To try to find out what happened, I started from scratch. I put my router into 802.11n which lists it as "performance", then added a static IP to my Nexus 7. I immediately had 58Mb/sec. since 58Mb/sec > 54Mb/sec, I figured maybe I did get 802.11n this time since 802.11g gets 54Mb/sec in optimal conditions. When I went to check which protocol my Nexus 7 is using, I moved it in front of me, a distance no more than 18 inches, and saw my signal drop to next to nothing. I pulled up the Nexus 7's WiFi advanced settings to find out that I now only have 5Mb/sec and the protocol is now 802.11g. This means while roaming, if you hit a sufficient enough degradation in the signal, the Nexus 7 drops your 802.11n status like a hot potato and no, you can't get it back unless you reset everything. I mean at least, to date, I have not found a way to keep a device configured to stay with 802.11n even if the bandwidth drops.
Since I was given a drop down menu in my router as to which protocol I wanted to use and since the 802.11n specs say it is all or nothing, I thought that the router would enforce 802.11n and not allow a legacy NIC to connect to it. This is far from the case. Why they even give us a drop down menu if they are always going to do 802.11b/g/n anyway is beyond me.
Now that I have seen Nexus's wireless protocol drop from 802.11n to 802.11g outside of my control, I want to find all devices that misbehave like this and see if there is anything I can do to force the client to stay on 802.11n. Obviously, I also have to eliminate dead and near dead zones.
Just thought I'd share the all the fun I've had getting to this abysmal point.
I will dig into our smart phones and tablets another day to see if I can force it to stay with 802.11n even its Rx signal attenuated for a few seconds.
I hope this helps others and if your experience is different then mine, I'd love to here what your findings are.
You may be fighting interference not only from the neighbor's WiFi, but appliances in your home. Possible sources for rf noise would include dimmer switches, CRT and plasma screens, microwaves, cordless phones. An rf detector can be bought or built or an am radio tuned between stations can work.
I've seen anywhere from 5mbps to 300mbps connect speed, it can change in one session if the router dynamically adjusts throughput. Also, there may be a power level setting in the router setup to get your signal farther above the noise floor.

An easy rf detector: single coil electric guitar pickup and cheap practice amplifier sourced from a guitar shop. Ask the guitar tech for a good used p/u, they swap them out all the time.
The wider channels used for faster throughput will be more susceptible to interference than the g standard,IMO.

Wifi cuts out when bluetooth is in use

Whenever I have both bluetooth enabled (and paired with any device) and wifi enabled, and I'm streaming music (Spotify in my case), after several minutes (almost randomly), the internet will stop working. Meaning, the WiFi icon will still show as connected, but it can't connect to anything online. I typically have to disable and re-enable WiFi for it to work, but then it would do the same thing again.
The strange thing is, my Galaxy S4 had the exact same issue/behavior. On both devices, I've seen this behavior regardless of the type of WiFi connection and/or bluetooth device (I've noticed it with my skullcandy headphones as well as my Sync in my car).
Do these devices share the same bluetooth/wireless chipset? Is it an Android thing? I'm forced to either use 4G with bluetooth, or WiFi with wired headphones. Thanks.
EDIT: this is using 5ghz Wifi.
What version of android are you on ?
carrier phone or unlocked. Some times these issues are carrier specific and non existent on others.
If you go into settings - wifi
Uncheck any option that says switch to data if wifi is unavailable.
I can confirm that this is an issue, I experience the same problem on my g4 818p

WiFi goes on 2.4ghz or 5ghz(most commonly on 2.4ghz) Bluetooth works on 2.4ghz. Unless you are 1m from router, BT is going to butcher your wlan. Had the same problem before. Solved it by buying dual band modem-router.
You could forcing different channel in wlan settings.
http://smallbusiness.chron.com/fix-bluetooth-wifi-interference-71008.html
idea here is reducing interference to bluetooth from competing sources.
- switch off wifi and use data which the OP is doing. Curious that the problems occur even at 5Ghz. Would have thought that band would be relatively immune to 2.4ghz sources.
- reduce the distance between bluetooth device and phone.
- move away from any sources of wifi interference if wanting to use bluetooth.
And now from the ppposite direction. Preventing bluetooth from interfering with wifi

Read the comments below. similar to the OP.
The key is more management of the problem rather than solution.

I'm using the Verizon variant.
this issue hunted me on all software version
Many options live
Router: Try another chanel
Router: Try only 2.4 or 5 Ghz
Router: Try only N or try only b/g/n mixed
App: Delete tunin radio
Last options send back service mainboard change.
i m facing the same problem but only when i do cellular call,
i am using realme wireless earphone , when i used to call my wifi speed gradually decrease , and after that stop working completely..,
after disconnecting the call i need to OFF and ON to work wifi again....,
My wife got the same issue with a Samsung A40 (and before with a Motorola), when using 2.4 wifi and Bluetooth connections (band and speaker for instance) the wifi is hanging. With wifi 5 it's ok. I don't have any issue with my phone using same network. It's crazy.

Fire TV Stick - wifi problems due to Wifi direct remote

I wonder if anyone can advise how this problem might be fixed:
I have a fire-tv stick in my bedroom the latest version which has a voice remote and connects using WiFi direct instead of bluetooth. I'm using 2.4Ghz wifi (using a TalkTalk hg633 super router). I can't use 5Ghz because the signal to my bedroom isn't good enough on 5Ghz. On 2.4Ghz the link score from inSSIDer is 91 with the fire-tv stick unplugged, with a signal of -50dBm. With the fire-tv stick on a WiFi Direct AP appears on inSSIDer with a signal of -39dBm (ie stronger than my normal wifi signal). The link score drops to 71.
If I test download speeds and pings, then with WiFi direct off, i get decent downloads speeds (around 20Mbps) and 18ms pings in my bedroom, in the lounge its a little higher. With Wi-Fi direct on, download speeds drop below 7mbps, sometimes 1mbps, pings increase to 200ms (although I have seen 10,000ms) and the connection often disconnects so the download speed test or ping is unable to complete. (I get about 2 tests that work out of 6, the others fail due to connection issues).
The upshot of all this is that I can't get a reliable streaming service on my fire-tv stick. especially in the evening. The network often disconnects, or slows to a crawl so I get frequent buffering, inability to stream at all or a poor quality picture. In the lounge, I often find my PC disconnects when wifi direct is on though streaming is less of a problem (because there the wifi signal is about 5dBM greater than the WIfi-Direct signal
I contacted amazon, and they suggested changing the channel of my wifi so it isn't on the same channel a Wifi Direct. That doesn't work because the WiFi Direct signal follows my wifi onto the same channel.
I can't use a lan cable (no option for this on a fire-tv stick, and I shouldn't have to in any case). I don't want to add extra extenders / APs to my wifi network as that might just make things worse.
Does anyone know of any way to switch off WiFi direct and use bluetooth for the remote or the FireTV app on my phone instead? Or to decrease the power of the wifi direct signal, or any other solution?
I wonder about switching to an older fire-stick with bluetooth remote - but that I think would mean I lose the voice search facility?
If I swapped to a full Fire TV with voice remote - do they use bluetooth or Wifi Direct?
Same problem. Not as dire a situation because it's in my kid's bedroom and not mine. :silly: But it interferes with the WiFi signal in areas that are closer to her room than my home router.
Not sure why AMZ chose to use the same channel as the FireTV stick talks to your WiFi network on to do their communication to their remote. That seems like a really bad design - if it's messing the 2 of us up, it has to be doing the same for a whole lot of people.
I tried changing my home WiFi from channel 11 to 1 in troubleshooting and had the same experience as you - the FireTV stick's WiFi changed right along with it to continue to clobber my home WiFi signal. Been through the menus in FireTV stick - no way I can see to change its behavior. Google search led me here.
Hi,
Whilst I stand by everything I said, in attempting to get Amazon to replace my remote with one that used bluetooth instead of wifi-direct, they sent me exactly the same remote in replacement. It still uses wifi-direct. However, it has worked fine, despite being on the same channel. That suggests that some remotes are faulty and causing or exacerbating the problem. Exactly why that would be I don't know, but it's all working fine for me now.
Roku has been doing this for years Here is a link to there form maybe amazon will listen I just got a new one for another room but no network problems and is faster on menu loading so I can live with it.
You're always gonna have problems with a ton of stuff on 2.4ghz. If your router has 5ghz, I would recommend reorganizing if possible, or getting a stronger router. 5ghz means no headaches, no problems with other things, controllers\remote work fine, etc.

App That You Select 2.5ghz Vs 5ghz WiFi Frequency? Constant WiFi Authentication Issue

I am looking for an app that lets me control what frequency my phone uses for WiFi.
Alright....I am so sick and tired of all the issues I get with WiFi on my Nexus 5x. It seems like every new build I get more and more issues. Stock, Pure Nexus, and RR Roms have all given me issues.
I know that this was an option in the WiFi settings pre-Android 6.0. With how many issues with WiFi has been present in N and M, I have read that controlling what frequency has helped other people.
With the removal of the WiFi frequency option the updated WiFi code is going to try and secure the best connection. The problem with that is my Nexus 5ghz doesn't like connecting to 5ghz. The issue is that my works router has multiple Access Points that broadcast in 2.5ghz and 5ghz. My phone won't stay connected to WiFi because it connects to a 2.5 and then goes to a 5ghz thinking it is a better connection
