Problems with 5GHz WI-FI - LG V20 Questions & Answers

Hello Everyone.
I've got a problem with my WI-FI in my V20 that doesn't allow me to connect to 5GHz at all.
I tested the WI-FI with an analyzer on my phone and it didn't pick anything up which normally it should pick up around 4 different ones, I also tested it on my PC which is next to my phone and it picked up all them perfectly fine.
I'm in the UK with a virgin media super hub 2, I also tested it with a TP-Link C2 which is the one upstairs and nothing still. I know it's not my router as I have about 6 other devices which connects to 5GHz perfectly fine, so I know It's a problem with this device.
This is my 2nd V20 as my first one had the WI-FI problem as well and I hoped I just unlucky with that one and the replacement had exactly the same problem.
I brought it from ebay by the name of eglobalcentral-gb. They quickly got in contact and everything. Perfect communication. The 2nd device was also from this person as well.
The phone is also the H990 duel sim version.
Thanks Ben

Wifi help please!

Was wondering if anyone could help me.
I was loving almost everything about my elocity tablet, but wifi issues were same as initial g tablet.
Firmware came out yesterday that supposedly fixed this and for everyone in the main Elocity thread, it seems to have just done that.
I have applied it but have the following problem:
While I can see all the available networks, I cant seem to join any unless I am almost 5 feet from the router and despite seeing excellent signal I am only getting 1 mb/s link speeds. Rarely it wil go as high as five.
It is not a router issue as laptops and iphones connect fine. I have rebooted router and tried every permutation of wireless secuirty and wireless speed, b/g/n settings (the elocity is b/g only wifi). With no luck
Went to local McDonalds and could pick up 4 surrounding wifi networks with good to excellent signal and connected to them but again only a best of 1 or 2 mb/s.
I will be returning my device on account of this. Being in Canada I won't be able to get another (I am in USa with family for holidays for another week.)
I am hoping there is something in software I could do that might fix this as I like the device otherwise especially with quadrant scores in the 2400 range now.
I tried resetting the device and reflashing the firmware update to no avail. I don't know enough about android or linux to know if there is anything I can do delving deeper into the device to fix this?
It is almost like it only connects at wireless b and not g working so range is short and slow.
any thoughts or ideas before I send back as I have 2-3 days to wait for the RMA label.

[Q] Tab 4 7.0 forgets wifi

After an hour on the device it simply forgets it's connected. Even if I'm watching a movie it will stop aND say no connection. I've returned it once so I think it is software vs hardware. Anyone else?

I had a 7.0 for a week and not one had problems

Yeah mine does that also, not my fave, but I just turn the wifi off and then back on again. Sometimes it only stays on the wifi for 10 minutes! Hope there is a fix at some point.

Seems like a Samsung issue....
Looks like all along the Galaxy lineup there are wifi issues.
I tried everything, preventing wifi from sleeping, using wifi fixer, nothing seems to work.
Sometimes my wifi will stay connected, the upload will work, but I get no download.
Rebooting wifi on quick toggle seems to only do the trick.
Have you all updated the software?

Yep, I updated to the latest software the moment I received the tab
Hmm, have you tried with more than one WiFi connection?

Yep, seems to do it more often with a 5Ghz connection than 2.4 though.
None of my other 5Ghz devices (3 iPhones and an iPad) drop wifi.
Signal is on clearest channel available.
Pretty much isolated everything outside of this tablet.
I'm pretty techy with my home networking, so I'm at a loss with this one.
Yes, it has been updated and yes it has occurred on my home wifi, my work wifi, my doctor's office wifi, and unfortunately the hospital's wifi. All with the same outcome! My S5 doesn't do it nor did my S4 running Kit Kat.
So, still no fixes for this! As a previous poster now it is getting where if I'm playing a game it will drop after 10 minutes! I have power save off everything. While hitting the WIFI on off button works it is highly annoying! I want my WIFI all the time not when my tablet thinks I should!

Think I have a solution http://tinyurl.com/nfbgxds
Hope 5th is will help out so far so good for me!
I just got this tab 4 7 inch last week and I am having the same problem with connections showing connected but not having any data transfer. The steps in the above link did not help for me.
I have updated to the latest firmware posted on sammobile, both the Canada version and the nook (BNN) version. Neither have made a difference.
I have found another thread in thisnforrum for this same problem, and there wasn't any solution there either.
I did find wha I think might be solution but haven't proofed it yet. in the build prop there was two "ro.carrier" lines. I think there is only supposed to be one, so I commented out one.
Original Example:
ro.carrier=wifi only
ro.carrier=unknown
Changed example:
ro.carrier=wifi only
#ro.carrier=unknown
If anybody can confirm this makes a difference or not please post results
EDIT::
After two weeks without problem anymore it appears the fix was the static IP address not the build prop change.
I found threads going back to at least 2007 about Samsung devices having trouble with dhcp and all the solutions being manually assign a static IP to the device.
Same issue here. Sometimes I have to cycle the WiFi every webpage!
Both of the above solutions didn't work for me, unfortunately.
Edit: Okay, I may have found the issue, at least for me. Turns out, the tablet was auto-assigning the same IP as my RasPi. After setting a static IP, everything looks okay from here. Hope this helps!
Changing to static IP did nothing, I was having to reset wifi on the tab every time I turned on the screen.
I even had wifi fixer constantly running.
Finally updated to NJ3 and everything is working properly.
Looks like it's a FW issue.

It should be one line:
ro.carrier=wifi-only
Script can be added however by attacting to the rom on the correct line parameters and scripting for digital on board configuration (no smart card) QMAL gsm, gprs, 3g, 4g, even lte or 5g, or 6g, no sim card required researve slot for world phone, or dual networking. The problem is each phone has to be separately programmed so cell companiesnhave walked away from needing higher qualified employees by switching to smart cards. Cost way less and employes way less people and note, your phone didnt cost you a penny less. I been doing cell phone tweaking since the motorolla brick was cool. Currently I used Samsung Galaxy Note 8010 64-bit 32 gig converted to XAC (its the industry's mobile payment recieveing device you see at bars, its made from the model previous mentioned)[to-wit-it says on their site not to tell anyone about]-or else- build then added Debian, Jessie. Then switched the imei to XAC, installed the telephony.manager.is_network_roaming=true along with the prpper scripting for the support and am hooked up to Sask-Tell. Once I got it connected and registered so it had a sign in address with the system i swutched the imei to all 000000000000's now they dont even send me a bill. But it works. The guy at the phone company couldnt even tell me where i was calling him from and he said my phone was disconnected while I was on the phone with him from the disconnected number. lmfao have a good day.

D800, bad wifi, bluetooth connectivity

I recently just purchased a Razer Nabu x. I was totally excited to start using. Well, I thought it was defective, since it kept disconnecting. I tested it on a Nexus 4, however and it did not disconnect. I even downloaded a signal meter on both phones. The nexus 4 read nearly full bars when next to the smartband. My d800 read two bars next to it.
So, my bluetooth is screwed. What else is wrong? My WiFi. Where my girlfriend's phone (the nexus 4) can connect perfectly fine to our school's wifi network at nearly all times. Mine insists on being a chode about it.
It will say that the signal is Excellent. I click it to connect. Either a) nothing will happen or b) it will flash to 'connecting' for a split second, then return to saying 'saved.' It's also worth noting that after it says 'connecting' for a second, the signal usually drops to poor. It gets subpar signal in my room. Next to the router. Granted, it normally works fine on my home wifi, and i can understand that the school's wifi is probably a little harder to connect to, but it's significantly worse than my old phone (which is my girlfriend's current phone, the nexus 4 I mentioned earlier)
I've installed a couple roms on my phone, and even on stock the wifi was a hassle and refused to connect. I'm currently running Resurrection Remix I purchased the phone used, with no information except that it had a clean ESN so I don't know of any damage that would have been done to it.
Has anyone ever had a similar issue with bluetooth/wifi? Just absolutely awful signal, reception, connectivity? if so, how did you fix it? And would it be possible to REPLACE the wifi/bluetooth antenna?

Wi-Fi Channels 12/13

Anyone having issues connecting to wi-fi networks on channels 12/13? On my device I'm unable to see SSIDs in these channels most of the time. Sometimes I can see networks in channel 13.
Am engaging with Google tech support, so will keep you posted.
What country are you in?
UK
I seem to be the only person on my street that knows channel 13 exists. No issues for me connecting. Although I run my phone to my 5Ghz connection normally, I can connect to my 2.4Ghz if needs be.

Good good.
I'm wondering whether it's down to me not activating the SIM in the phone as yet? Like a double check that the phone should be allowed to use 12&13 (rather than just selecting English UK as the language).

There's really no difference in using that over channel 11 in your case with the co-channel interference.
YES!
It's not just me then. Home router (2.4Ghz) is on ch.13 and when i return home the device will not auto-connect until i toggle wifi off and back on again. Wifi works fine until i leave again. connects fine to my wifi network at work but that is different channel and on 5Ghz too.
RMA'd my device and the new one was bad. Wouldn't see my network at all, but wouldn't register my Sim card either so I have just returned this replacement device. Replacement number 2 is on the way.
I switched to ch.12 and the same thing happens at home. Didn't try any other channels as they are too noisy. So I wonder if this is a software issue? I'm in the UK and the router is made by technicolor for Plusnet.

If channel 11 is noisy, then so is 12 and 13.

You might want to change to channel 11. With the current setup you are not only killing your own data rates, but also the rates of everyone on channel 11. These channels are not supposed to overlap, because that creates interference. Switch to channel 11.
This is my WiFi situation. I'm normally on CH.13, but switched to 12 as a test.
My 2nd unit arrived last week, and unfortunately it's the same issue as before - no channels 12 or 13, not even visible. I'll be back in touch with Google today.
Hopefully this is a software issue rather than Google/Huawei spec'ing a duff wifi chipset.
Google spoken to and basically it's a case of tough-titty - some devices aren't going to work with channels 12 & 13.
For anyone else reading this, I had this problem and 'solved' it.
If you find that you can't see channels 12 and 13 then it's almost definitely caused by the Wifi country code restrictions.
I got my Nexus 6P here in Korea and initially tried it out with no sim card. Even though the location is set in settings, without a sim card it doesn't get the wifi country code set, and I couldn't see those channels. As soon as I inserted a Korean sim card, I was able to see them.
If you are in the UK or elsewhere, using a local sim card and you can't see those channels then chances are either your country doesn't allow it or the code is already set. Either way, your options are just accept it or try one of the 'not officially supported' ways to getting around it. That's likely why Google said you were out of luck. It's possible but involves rooting etc. I think. Just search for 'change wifi country code android'. Good luck.

I am afraid that the issue is not as simple. I also have problems with channels 12 and 13, however my phone can connect to those channels, but only for a while. I quote the report I filed in the AOSP bug tracker (not yet assigned, though):
Before I continue, I am based in Switzerland, use a Swiss mobile provider (Swisscom), and I bought my phone through Google in Switzerland. This is relevant because in Europe 802.11b/g/n channels 12 & 13 are allowed, while in the North America they are allowed only under "low power conditions" with the effect that, AFAIK, many devices simply do not support them. My Nexus 6P however should (and shall) support those two channels.
Now, the problem.
I have two access points at home, both in the 2.4 GHz band: one on channels 4+6 and the other (normally) on channels 12+13. What I noticed is that my Nexus 6P would initially connect to the strongest signal independently from the channel, as expected, but then after a while (a couple of hours, maybe) would just stop seeing the signal on channels 12 & 13. Not just my own WLAN, but also neighborhood WLANs on the same channels. This means that the phone can be sitting a couple of meters from the AP in my office (channels 12+13) and be connected to the AP at the opposite corner of the building (the one on channels 4+6). I checked with "WiFi Analyzer" and the phone really does not see any signal above channel 11.
Disabling and re-enabling WiFi will make the phone see channels 12 & 13 once again. However after a while the problem appears again.
At home this is just an inconvenience: I moved the frequency of the second AP to a different channel and that "solved" the problem. On the other hand this might be a much more serious problem when I am in an environment where I can't change the WiFi settings. Maybe I want to connect to a public hotspot broadcasting on the "wrong" channels or I am at the office in an area covered by APs on channels 12 & 13. Tough luck.
Incidentally, I saw at least one report of someone who had exactly the same issue: he had to disable WiFi and enable it again to get the phone to connect to his WLAN (on channel 12 or 13, I can't remember). I also have to say that in our household we have a few other Android devices (2 x Nexus 7, 1 x Nexus 9, 2 x Nexus 4, 1 x Moto X Play) running either 6.0.1 or 5.1.1 and a few other devices (iPhone 5S, iPhone 6, laptop, 2 x Kindle) and none exhibits this behavior. It seems to be specific to the 6P.
I suspect that after a while the WiFi driver simply reverts to its default regulatory domain ("US", I assume) and stops listening to channels 12 and 13. Why it might do so is anyone's guess. Maybe doze interferes with the driver.
Same problem here. The only way to reconnect to WiFi channel 12 or 13 is to manually switch WiFi off and on again on the 6p.
I'm in Hungary.
Guys, there is a thread in the Nexus Help Forum and I reported the issue in the AOSP Bug Tracker. Add your contributions to those threads and star them. Let's try to bring this to Google's attention, otherwise we will never get any action on this topic.
Edit: For some reason I can't add links to the post. Please search issue 197106 ("WiFi 2.4 GHz channels 12 & 13 not working properly on Nexus 6P running 6.0.1") in the AOSP Bug Tracker and the post "My Nexus 6P can't connect to Channel 12 or 13 WIFI's" in the Google Product Forums.

I have been trying for a week to extract some information from Google and Huawei, but I must say that their support just doesn't know anything about this issue. It's even difficult to get someone to understand what the problem is: one Google support guy thought I was talkng about LTE channel 12, for example. Huawei support started talking about options in the WiFi settings that are not there, then they wanted to guide me through adding a new WLAN, and finally started clutching at straws, giving more and more fantastic explanations of why it might be so.
Bottom line is: nobody I talked to ever heard about this issue.
I would really like to understand if it could be a hardware issue (which I honestly doubt) because my RMA window is closing soon and I don't honestly know what to do: apart from this WiFi issue my 6P is absolutely flawless and I do not want to risk getting a new telephone only to find out that WiFi still does not work as expected and it's also got other issues. (And, yes, something like this already happened to me.)

Hello, I also have the same problem. As I can report it to Google? I have not found a way.

Did you call the Google Store Support? I hope that if they hear the same reports repeatedly they will take notice.
If your telephone is unlocked (and if you are on XDA chances are it is), flash Franco's kernel. I did it today and now my problems with WiFi are gone. Plus Franco's is known to be very battery efficient. It's a win-win situation.

Does Android 11 OB2 fix WiFi Issues, 2nd SIM, and can you root it and use GPay...?

Title pretty much covers it.....I have had it with the WiFi issues on the OP8 Pro and was going to go back to the OP7 Pro.
....but people are saying that they are all fixed in Android 11 beta on the OnePlus forums...is this true? And what about Dual SIM which I also need on occasion?
If I move to A11 OB2, can I root and get GPay working?
Is it stable enough to be a daily driver?
Many thanks in advance...

You can root OB2 device, and the OB2 seems usable and also stable enough for daily usage.
I recently acquired a oneplus 8 pro purchased directly from oneplus.com. I have model IN2025. It is the 12gig ram 256 gig storage version. I also have a samsung active watch 2 which I again have had no problems with my oneplus 7 pro. When I initially acquired it, I tried using it with the android 10 non beta firmware. I had multitude of issues up to and including:
1. high difficulty (to not at all) connecting to either my 2.4ghz wifi network OR my 5ghz network. It would state connecting however stall at obtaining IP address. No other devices have issues connecting to either networks including my older oneplus 7 pro.
2. if it would finally connect, while it may state that the 5ghz is connected at 300mbps or the 2.4ghz connected at 144mbps, with random speed tests I would not experience anywheres near those speeds (my ISP dishes out 200mbps). at most I would get 30mbps on my downstream....again if it even worked.
3. both the 2.4ghz and 5ghz networks would often disconnect and never reconnect if and when they did successfully reconnect
I installed the open beta 1 and then did OTA to open beta 2. This has helped quite a bit HOWEVER I've experienced the following issues:
1. while I have no longer received the locking up on obtaining ip address, even if it states I'm connected to my wifi (either the 2.4 or 5ghz) the network is still extremely slow
2. sometimes the device while connected to either wifi network will appear to not send any information aka stall which potentially makes using google messages over wifi unreliable as well aka text msgs show up late etc
In both pre and after beta installation 5g has been significantly slower than 4g cellular data(though I can't say much to that as more than likely the 4g in my area has towers closer near by). Also while on 4g or 5g cellular connections I have though not as frequently experienced data stalls.
Things that have helped resolve some of my issues:
1. this I believe is the largest potential bandage: make sure use device mac address NOT RANDOM is selected. After having done that my connecting to the internet appears to be better (even if it still stalls out)
2. while I've not tried it alot as I use bluetooth alot (with the watch I have and my car and wireless headsets)I've read that turning off bluetooth can help both wifi and cellular data issues
I am currently in the process with oneplus of returning the 8 pro for a new 8 pro as I have not owned/had the phone for greater than 15 days. If that does not resolve the issue, I too may go back to a oneplus 7 pro...or perhaps the 'dark side' and go the samsung route.

Excessiveidling,
This is exactly the type of info I was looking for. So it sounds like it is better, but still bizzare WiFi issues that no other phone on the market has. My situation is...
I have to leave bluetooth on because of watch and hearing aids
I need to rely on WiFI calling on occasion and need it to be 100% reliable.
I need working WiFi at home because I use my phone for some applications that connect via my home network, so having WiFi work "most but not all" of the time is a deal breaker.
So at this point I think I am going to switch back.
I've been a loyal OP fan for quite a while (4 phones now), this has been really disappointing. I even bought a new router because someone said WPA3 would help...but it didn't.
MW
While I can not say anything to the validity of the following statement...I have heard in other forums that the samsung devices with the same qualcomm chipset had wifi/cellular issues (especially with 5g).....that was only ONE forum post however unlike the multitudes of forum posts I've seen regarding the oneplus.
If I were to guess, only based upon my limited modding experiences with previous android phones, an updated modem/chipset software COULD resolve these issues...further more a different/modified kernel as well. Doing that would probably void any warranty though and for spending 800+ on a phone, you shouldn't have to modify in order for it to work just as well if not better than an older phone.
I'll let ya know how the exchange goes. I'm willing to give them another shot 1. because of my excellent experience with the 7 pro and 2. because I've seen so many posts, reviews, etc stating the oneplus 8 pro is THE PHONE to have overall.
Thanks,
E|
I read the same thing re - chipset, and agree that is a possibility. The other is a horrible RF design for the BT / WiFi antenna because they crammed in the wireless charging.
But I don't see any of this getting fixed anytime soon. I wonder if the OP8 (non pro) has similar issues -- I didn't check.
Let me know how your new phone works out - an RF HW update or a new batch of chips could change things.
