Wifi Tether BUG - no Internet on newer kernels KG5 and higher on my Lenovo Laptop

I recently encountered a weird bug when SGSII would establish wireless "g" connection at 54mbps (instead of regular "n" at 65mbps) when doing 3G to wifi tether on my Lenovo Laptop.
My other 2 laptops work fine as expected, however after doing some troubleshooting, its concluded that the wifi router IP forms a "black hole" hope because of which the external communication to Internet dies after 4 or 5 hops (internal to the ISP). While doing a Trace route, the first hop (the IP of the phone's wireless router - 192.168.43.1) doesn't respond to the trace route ICMP requests and fails, however it does work for the next 4 hops before eventually dying after that.
This proves that wifi connectivity between the phone and laptop remains good despite it being downgraded as "g" network when my laptop is capable of "n" at upto 300mbps.
Never had this issue before KG5 or higher builds and it seems all the custom kernels and ROMs based on these newer kernels are affected.
As this issue is affecting only my Lenovo Laptop, not sure if it was ever reported.
Fortunately I am able to flash kernels based on earlier than KG5 build like Ninphetamine-2.0.x (till 2.0.5).
All Ninphetamine-2.1.x builds and kernels like "RAGEmod v1-T30" are also affected.
I am currently on "TOUCH X-treme KH3 2.0 'PERFORMANCE'" ROM and fortunately it seems to be working fine on Ninphetamine-2.0.5 as per my preliminary testing.
I have 2 more laptops which seems to be working fine otherwise on any latest kernels.
I would appreciate if someone could shed some light on the reason behind this bug as I am still investigating the cause and on a fix other than older kernel versions.
My primary usage of this phone is completely impacted by this bug and I hope Samsung would be able to resolve this bug before their next official release of 2.3.4 or higher version builds.

Hmm like the battery drain while charging bug on SGS1 I seems to be the only person shaken up by this bug which makes my SGS2 completely useless when using the latest kernels/ROMs.
My laptop has Intel WiFi Link 5100 AGN. Can someone having same/similar Wifi adapter report their experience?

Not surprised that Wifi tether is not used by most of us and hence such bugs go unnoticed and I paid a HUGE price of crashing my laptop which trying to fix the issue as I never thought it is the phone doing something weird which is preventing my laptop to get proper wifi connectivity.

Unfortunately no resolution till date. All the latest kernels and ROMs are affected. Not sure what is the issue as it defies logic why only one series of Wifi adapters are affected by this bug.

No resolution till date. All the recent kernels are still affected except the one on CM7 ROM.
Seems I need to wait for this update to become official in India before raising with Samsung here.

Ahhh.. Finally a respite after several MONTHS! The latest Siyah v2.5 kernel (http://forum.xda-developers.com/showthread.php?t=1263838) with new Wifi Driver has restored Internet access through Wireless Tether though the speed is still limited to g instead of regular n at 65mbps. But atleast I can now switch from the good old Ninphetamine-2.0.5 kernel to this latest kernel I always wanted to keep. Such a RELIEF!

I have faced the similar problem. But how my problem was solved is give below:
Update you windows OS using windows update
Then manually switch off the radios and switch on
That's all and now I can use wifi tethering as normal. First check with second option, if doesn't work, then try updating the PC OS too.

Latest Siyah 2.6.x kernels have AGAIN brought back the bug on my face!
None of the other options you suggested worked. I have spent hours trying to figure it out and this is what I get when I am affected:
Tracing route to 8.8.8.8 over a maximum of 30 hops
1 * * * Request timed out.
2 164 ms 123 ms 127 ms 218.248.84.5
3 228 ms 68 ms 81 ms 10.42.43.101
4 79 ms 79 ms 80 ms 10.42.43.28
5 * * * Request timed out.
Doesn't make ANY sense on how the first hop is getting blackholed when it otherwise respond to ping requests. I am able to reach till the last hop of ISP before dropping off.
Can any network gurus out here explain this phenomenon? I am unable to locate any logic behind it.
Hope Siyah team fixes it soon for me to enjoy a glimpse of Voodoo Sound on my SGS2.

I have a Lenovo T520 and am using the KK2 stock firmware/rom with no problem whatsoever in tethering...using it at this very moment

It actually seems to be affecting only Intel 5100 adapters like on my R400. I have 3 other laptops and a mobile phone which are working fine otherwise
As I said, it defies logic why only this adapter has compatibility issue when even older Intel 39xx based adapters work perfectly fine otherwise.

Fixed in Siyah 2.6.2 kernel again
Finally got it fixed on Siyah 2.6.2 kernel (to be released shortly) while working directly with the dev "gokhanmoral" in the past few days. All seems to be working now like it was in 2.5.x builds for me.
I sincerely thank gokhanmoral for taking the pain of looking at this isolated bug by Samsung which has fortunately been resolved on the latest drivers (to an extend, still no n mode access).

Wifi Signal Strength Issues

I've been looking everywhere for solutions to the weak Wifi on the Nexus 10, but didn't find any solutions yet.
The network also has an added wifi repeated connected via LAN, but still the Nexus keeps 1-3 bars of wifi.
I have another 5 or so Wifi devices, Galaxy S2, Lumia 920, iPhone, 2 laptops. None of these have any issues and are always on 4-5 bars, usually max all the time.
I've tested both on 2.4ghz and 5ghz, both to my Asus AC66U and also to an old RT-10, one Huawei, etc.
It's very clear that no matter the band or router settings, the Nexus 10 really has a weak signal reception in comparison.
Since the Nexus is new for me, it's on 4.3 and I don't know how it performed earlier.
Are there any other modem drivers or similar that can be flashed?
Any other experiences with custom ROM's?

Wifi strength has been a little weak since release honestly. Has been mentioned alot here and around the web for a while.
Now my problem since the latest update has been wifi drops where I lose wifi transfer completely even though the wifi icon shows a good connection.
I think this is something new (i know it is for me at least) and have been looking to see if anyone else has seen this issue in the latest software release.
If I toggle wifi off/on it works after but it is a huge pita.

This problem (wifi icon gray and no internet connection) started with 4.3 for me without question. Previously wifi connectivity was rock solid and I never gave a second thought to it. Nothing changed but the android version. I hope it is fixed in 4.4.

Yeah, another guy at work told me his is doing the same after 4.3. Surprised we aren't seeing it mentioned more around here.
Anyone else seeing wifi drops?

mine was doing the same thing. i tried clearing the cache, uninstalling apps that i thought might interfere and then a full factory reset. still had the same problem. i rooted and then did a factory reset from recovery and it hung up reinstalling apps so i did another factory reset still in and out. i did another factory reset and logged into my wifi and left for a few hours to work on something else. when i got back the signal showed full and about half of the apps installed. i reinstalled all of the apps that hadn't installed and it's working fine now. not sure why i had to wipe it 4 times but it's working fine now and streaming movies without a hiccup. i guess something kept getting corrupted during the setup or reinstall of apps. anyway it's been working fine for a few hours which is the best it's done in the last month.

nexus player cant recognize 5ghz channel

my 1 day old nexus player cant recognize my 5 ghz channel ,no problem with the 2.4 ghz.

I couldn't connect to my 5ghz router (tplink archer c7 v2) even though other devices could. However none of my other devices are ac, the others are N 5ghz. On a hunch, I went to my router's config and disable ac on the 5ghz then the nexus player connected immediately to the 5ghz band. I don't know if it's an issue with the archer c7 or with nexus player but at least I have better speeds now.
But if there's something else to change I'd like to know because I'd prefer to use ac.

I have the same exact router and I am connected to 5gz with my Nexus player with AC enabled. I am not able to confirm if Nexus is actually connected as AC just yet. I will confirm and post back, but I just wanted to let you know it is working for me with AC on. I am using the stock firmware, no DD-WRT for what it's worth. I also did not see any stock firmware updates for this version of the router.

Interesting, please let me know. I had openwrt on it for a bit but had issues and went back to stock. But I am on tplinks latest firmware. Released in April of this year. Maybe let me know what firmware version you currently have. I may revert firmwares.

I have not been able to find a way to determine if the Nexus is connecting with AC or not, but AC is on and it is connected to my 5gz signal. If you know of an app or some other method to find this out, let me know. So far the few apps I installed didn't tell me much. I am rooted with Stock at the moment, so most apps I need to test in the Play store require to find the apk to sideload. I hope the Play store blocking what I can and can not install goes away when I install a custom rom like Lollirock or AOSP 6.0 onto the Nexus. It says it isn't compatible, but it loads up just fine when I sideload it.
Then the last time I checked tplinks site for firmware, there was none listed. Then after I saw you mention the April update, I checked their site again and now see they just released another one on Oct 14, 2015. I have not updated it and my release listed in the router is Firmware Version: 3.14.1 Build 141030 Rel.56452n Hardware Version: Archer C7 v2/v3 00000000 The bottom of the router is listed as v2 though. It may be worth testing unless you know of a way to downgrade to my version easily.

Hmm, where are you seeing a new firmware dated Oct 14, 2015?
When I look here:
http://www.tp-link.com/en/download/Archer-C7_V2.html#Firmware
The latest firmware I see is dated April 27, 2015 which I am currently running. It's listed in the tplink admin login as:
3.14.3 Build 150427 Rel.36706n
Hmm, I don't see your firmware build even in the prior ones.
There are only 3 firmware versions in total. Mine & Archer C7_V2_V3_141110 (dated Nov 10, 2014) & Archer C7_V2_150304 (dated March 4, 2015)
The only thing I can think is you have never upgraded the firmware on your tplink and they don't post the stock firmware? Although I thought there were more than 3. Maybe they remove older ones. I'd be curious if you can connect with ac on the latest firmware but I don't think you can roll back to what you are currently running. Unless you're looking at a tplink page that I am not.
Yes when you go to a custom rom you won't have the market limitation anymore. I'm still on stock but probably going to go to a custom rom. The only negative is I don't think the remote is currently working. I may wait and see.
Regarding confirming if a device is connected as AC or N on 5ghz, I have no clue. I've seen a couple of friends routers (different models) and they don't show it either. Kind of annoying. However, I believe yours is probably connected at ac, as when I leave ac enabled the nexus continually fails connecting. Only when I disable ac does it successfully connect at 5ghz. Even though you may lose ac, you might want to consider updating as I believe they fixed a couple of serious security bugs in the older firmwares. That might even be why some are removed. I'm living with N right now, but I would like ac as I may move the nexus player to a room that's further away and ac supposedly handles distances much better than n.
Just as some tips for side loading. You probably know of apkmirror.com, which is good but doesn't have everything. There's also a chrome plugin for the market that gives you the option to download apks directly, and also install directly to another device. The second option doesn't always work though. the Nexus player may be greyed out when you try this but a lot work. So from my browser I'm just searching for apps and selecting install to the NP. For the others I download them and I was going to use ftp but I found it's easier just using airdroid which I already installed on the NP.

I was using this site: http://www.tp-link.us/download/Archer-C7_V2.html#Firmware The only difference I can see is this site is the .us version vs the .com version you linked me, which was the first time I seen this. I am located in the US, but it seems odd they would have different firmware downloads available between the 2 nearly identical sites. Then I either updated the firmware when I first installed the router, which was approximately a year ago, or I installed whatever was out then. I do not recall 100%, as everything was working I didn't bother with it. But now I am curious if it will help with security issues and/or break my AC connections.

I think the remote works, but it only has so many buttons, so it will dramatically limit your functionality. I plan on using a TV Launcher to replace the default launcher, no matter what rom, stock or not, I am using. It is designed for basic functionality so the remote should be just fine for it. Then I found a badass remote app called Droidmote on XDA and it works very well with the Nexus player on the stock launcher. I am sure it will work just as well with a custom rom too. I have it installed on my phone and tablet and was able to maneuver around every app I tested that I was not able to before I installed it and was only using the stock remote.

Yeah, I am not sure if I should upgrade to the latest firmware or not... but if there are a couple serious security bugs, I suppose I probably should update. Hopefully the October firmware allows AC to still work enabled. I sure hope so as I was planning on moving the Nexus to the opposite end of the house and having AC wifi is one of the main reasons why I chose the Nexus player.

I am familiar with apkmirror.com and similar sites, but I never dug into chrome with the market plugin. That is good info to know and may test it out, but I dont mind sideloading. I send the files to Google drive and load ES explorer and installs fast. However, I do prefer having the ability to do this directly from the Play store, which will be possible when I go to a custom rom. Anyway, if you update to the October firmware, let us know if it helped or made any difference. I will check it out myself by the weekend and post back if anything changes on my side.

That is strange but I've seen tplink do that before. I wish they wouldn't do that.
And your US site doesn't seem to have historical firmware available, unless there's a link I'm not seeing. I may flash this one and see if it fixes ac as I bought this as well with the intention of it being somewhat far from the router and would rather not rely on N.
Coll, I'll check out that TV launcher. If it works with the remote then that's a plus. One thing I'm not sure of, if one changes to a custom rom how does install the TV version of an app? Some of them are easier to use. Just wondering if the TV versions of an app will show up in the market when on a basically stock rom.

This problem has to do with the channel of 5Ghz, you need to select a low number channel otherwise the nexus play simply won't pick it up.
I have set 5ghz to channel 48 and works great.

I can confirm that I am running on a low channel (36) for 5ghz as well.

I have the same router. I ended up setting 2.4ghz to channel 1, and 5ghz to channel 169. Kept having issues with streaming Hulu, it would stop and buffer a lot. Seems better after I made these adjustments. I used a WiFi analyzer app on my phone to make sure I am not using channels that other people in the building are using.

That is odd. I have a Netgear true dual band AC router. My Nexus Player pulls and runs excellent on my 5G. Both my Nexus 6 and Nexus Player pull 800mbps link speeds on my 5G. Sounds like a router related problem.

I've had the same problem! It comes from the Location setting. At the very beginning, in the setup wizard you've set the location as US probably, and not all 5Ghz Channels are (legally) available there.
Change the location to the same location as your Router. For me that was the problem.

There is no where to set your location in NP.
Real life got in the way but I just tried this on every ac channel available starting from the lowest and the NP could never connect; disable ac and it connects instantly.
I'll see about flashing that firmware for the archer c7 v2 and see if that fixes it.

I had this problem with my Zyxel 802.11ac access point. Once I told my access point to stop trying to use 80Mhz channels (selection read "20/40/80MHz"; switched it to "20/40MHz") and went from forcing a specific channel to "auto" (i.e. let the access point choose the channel) the problem went away, and my Nexus Player has a nice strong, steady connection on 5GHz.

It is because Google fails to the DFS channels. I modded my Nexus 10 to get them but can't figure out how to enable them on the player. http://forum.xda-developers.com/nexus-10/general/adding-support-5ghz-wifi-channels-nexus-t2961722
Check this out to see the supported channels. (note 80mhz uses 4 channels.)
http://clients.mikealbano.com/

When I received and turned on my nexus player, it was not able to see 5GHz SSID. I immediately went and updated to the latest MarshMallow and now all 5GHz channels work without any problem. Those who had trouble with 5 GHz channels, are you all updated to the latest Android?

When you choose your language in the setup wizard. As long as I had there "US English" it did not worked. After choosing UK English or German ... well its working. I knew the trick from my Nexus 5. As I received it from Google Play I could not connect to the same 5GHz Network. I've called the Support and they knew from the beginning what my problem was and "advised" me to do this trick.
But I do not know, why you have to do this!

Wifi is unusable on android 10

Hi, I have a problem with mi redmi note 7 (lavender)
the problem is that the wifi gets disconnected at some distance (something normal from redmi note 7) the real problem is that it doesn't reconnect, even if i have the router with me, in the lower area of the wifi it shows the message "saved" i try to forget the network and reset the password but i still can't connect, I have to restart the phone to be able to connect normally, but after a while the problem returns.
I'm using a custom rom called AOSIP with android 10, I have already used pixel experience, Crdroid, Evolution x, Havoc os and absolutely, all have the same problem. I want to make it clear that I have already used android 10 on my redmi note 7 (pixel experience) and I didn't have any problems, the problem started after the February updates this year.
I don't think it's a hardware problem because going back to miui or a custom rom with android 9 solves the problem.
I would like to know if you already know about this subject or if you are already working on it or if there is a solution.
thanks
here are some links of the captures I made

I think you might be onto something. In my case, the problem has been with Wifi Tethering. The phone is basically unusable as a hotspot, cutting out frequently and randomly and I think this has something to do with your wifi problem, maybe a driver issue? Like yourself, I've tried several aosp roms, all have the same problem.
Do you recall the last Pixel Experience release without this wifi issue? I am considering rolling back...

Good morning, I've already tried the most recent version of pixel experience, in fact the AOSIP rom is from May 17, 2020, practically yesterday.
Obviously it's a driver problem, but I don't understand why all custom roms have the same problem and I don't know how to solve it either (in android 10)

Currently on StagOS May 11 build. I settled on that after trying Pixel Ex, Evolution, etc as it was the one with the least hotspot issues; which isn't saying much as tethered devices would randomly lose internet connection while the phone clearly had internet and you could browse on any browser on the phone.
Since you say the issue occurred for you after the February updates, maybe you could point me to the last stable build you used so I can roll back.

I recommend all the versions that are from February, I would like to use pixel experience from that date but the page only has recent versions.
if you want a specific version use Crdroid 20200209
crdroid if you keep your old versions in the cloud so I recommend it, but I can not guarantee that it is totally stable. Pixel experience if stable but they don't have the versions of those dates.

Currently on StagOS May 11 build. I settled on that after trying Pixel Ex, Evolution, etc as it was the one with the least hotspot issues; which isn't saying much as tethered devices would randomly lose internet connection while the phone clearly had internet and you could browse on any browser on the phone.
Since you say the issue occurred for you after the February updates, maybe you could point me to the last stable build you used so I can roll back.

I would like you to install the most recent version of pixel experience and when configuring the wifi, you will move away from the router until the signal goes away and try to connect again, just to check if it is really my phone or not.
Obviously making a backup before and also doing all this is optional. If you don't want to do it there is no problem thanks.

I already tried StagOs, I still have the same problem with the wifi, I also tried the hotspot and as you say if there is a data problem and in general it is unstable.
I downloaded the latest version of pixel experience and as expected the wifi was still failing, but the hotspot was working correctly so you can install it without any problem.

Okay sorry for the delay, been busy experimenting. Your recommendation of the Feb 09 crdroid build was spot on, flashed it, wifi and hotspot works like a dream, no issues at all.
After confirming that I decided to take a backup and try a recent AOSP build. I had already tried the Pixel Ex May 11 build and had the same issues so I downloaded the most recent build of Evolution X (May 17) and flashed.
So far, (Fingers crossed) I have not been able to replicate your WiFi issues or my tethering issues. WiFi did not disconnect even at a distance of over 50ft from the router. Keep in mind that these connection issues occur randomly but there's been nothing so far.
I will continue to use this build and test for the rest of the day. If I experience any dropouts I will restore to the stable crdroid build. Maybe you should try the newest evolution or go back to the stable crdroid to test if the issues are software related or specific to your device.

At this point I've been testing the latest build of Evolution (May 17) for about half a day, and zero problems so far, very stable.
I recommend you try it, may fix your wifi issues.

I am very happy that I found a solution to your problem, then I made some tests by creating an access point with my sister's phone ( xiaomi mi a1 ) and I performed the distance test and my phone connected normally. After several tests I am reaching a preliminary conclusion that there is an incompatibility with my router, I would need more tests with another router to conclude that my router is practically obsolete. That would also explain why I haven't found another thread with this same problem
good luck, tell me if you have finally solved your problem

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.
Just sharing my experience so far!

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.

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,

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.
