Lineage 15.1 Ping issue - LineageOS News & Discussion

Hi all,
I just installed Lineage 15.1 on Redmi Note 5.
I'm very happy with it, but I cannot resolve an annoying issue:
PING doesn't work from ANY apps, it cannot ping any devices in local network and doesn't respond to ping from
other devices. ALL other network functions are OK.
I have a lot of devices in the local network and they ALL PING each other without problem.
It seems that the ICMP echo request is DISABLED at all in the network stack and there is no option to enable it.
Can you confirm ?
Thanks

[Partially Solved]
I found the problem only happens when energy saving is ON.
If you switch to OFF ping works again.
Hope it helps.
Regards

Hi, good news.
I just upgraded to lineage 16.0:
here ping works OK also in extreme energy saving mode.
Bug of 15.1 ???

S5830 Wifi connected but internet doesn't work

Hi guys,
I've been trying to solve this on my own for a long time, but I've found no clue on how to do it.
I have an ADSL2 router with wifi at home and many devices connected to it via wifi (smartphones, notebooks, pcs) and every one of them works fine. Only problem is my Samsung S5830 which connects to the wifi, THE INTERNET WORKS FOR A 4-5 SECONDS and then it just stops loading pages and everything else, it is connected to the wifi but the internet doesn't work. Every other device works on that router but this Ace. Strange thing is, that on other Wifi (hotspot made by my HTC One) the Ace works just fine, so it is not a problem with Wifi driver/rom or something like that.
Solutions I've tried :
1. *#*#526#*#* code to restart wifi driver
2. Using Static IP
3. Changing DNS
4. Restarting router/phone many times
The router is TP-Link TD-W8961NB.
Strange thing is that I cannot even access the router's configuration page on 192.168.1.1 after that 5 seconds, so the problem isn't just in accessing the internet.
Also, I've checked all firewall/security/blocking functions of the router and none of them should be responsible for this, noting that all other devices work.
Thanks for any other ideas, I'm seriously fed up with this.

S8 Internet connection may not be available issue

Just got the S8 and I have 3 Wi-Fi access points at home to cover the whole house. My S8 has been registered with the passwords for all of the APs but it continually rejects the connections with an exclamation mark after the WiFi icon having connected and then shown a message that the Internet connection may not be available. The Internet connection is available as other devices are connected and using it perfectly. If I switch the Wi-Fi on and off and reboot the S8 the issue corrects itself but I should not have to go through that nonsense every time I come home and want to use my Wi-Fi. I have explored the advanced options on the connection settings and they appear to be quite limited (DHCP Etc). Is there some way to solve this issue? I have no problem with other android devices connecting to the same hotspots. Any ideas that might lead to a solution would be appreciated.

I had this problem when i first got my s8 from vodafone but when i got this latest update it's been good no issues with internet anymore.
I have this problem as well with my S8 from Verizon. Worked flawlessly for a week and them today I get this error. Very frustrating. I know the SMG955U from Verizon is already unlocked but is there any way to put the International ROM on the phone seeing that the Verizon and the International are the same?
I've tried all the resets etc and the WiFi connects but I get the 'Internet connection may not be available' message.
Update 27/04/2017
Thanks for the reply. My S8 developed some interesting issues including the switching on of 'do not disturb' mode intermittently and along with the Wi-Fi issue the mobile data was failing in areas where a full 4G signal was present. Rebooting, resetting etc did not resolve the issue and I returned the phone to CPW for advice. The staff at the Glasgow store wasted no time and exchanged it on the spot after some negotiation with their technical service centre. Full marks to CPW for the prompt service and I can report that all of the previous issues have now been resolved with the replacement handset. I thought it worthwhile to post this information so that others who experience similar issues may be able to get a similar resolution.
Poor WIFI performance
I also have issues with the wifi of the phone, /i will get the terminal replace some time today or next week.
1. WIFI keeps disconnecting, actually it's flapping connct&disconnect for 5-10 min until it finally connects, on this matter I have seen on the acces point that it tried to allocate an ip from an unknown without asking DHCP server for an IP renew it actually tries to alocate itself the last known ip, and clearly disconnects because of lack of internet access, this happens normally as power saving mode is on, disabeling power saving and assigning a static ip on the phone seems to resolve the issue.
2. poor wifi signal... no fix for this thus far
- i have 580Mbps speed connection on my S5 and only 120-240Mbps on my S8, steaming not working and connection in general very bad, time ots and stuf, although I position myself at 10cm away from the wifi router antenas i only get 540Mbps signal, although I have an AC1750 router , s5 gets 840 in the same spot... I think the modem(that is part of the Exynos chipset) does not work wekll with Atheros based AP´s , I have an Archer C7 with 2.4ghz QCA9558 chipset capable of 450 Mbps theoretical speed, but only uses 2 antenas as s8 only has 2 from my knowledge and reaches a max of 140Mbps(should of connected at 300Mbps at 10cm in theory ) with the s8 and QCA9880-BR4A on the 5ghz side of things with a theoretical speed of 1300Mbps should work at 866 with the S8 because of the 2 antenas of the S8.
phone changed 90% of problems fixed
Hello, just got my phone replaced, tha new unit has way better wifi signal considering I hace atheros router and the phone has broadcom 43xx chipset... worth considerign changing to a broadcom router...
Hi,
I have found a solution to this problem.
1. GO to wifi settings
2. Forget the wifi network
3. CONNECT AGAIN BUT BEFORE CONNECTING GO TO ADVANCED OPTIONS AND CHOOSE STATIC INSTEAD OF AUtOMATIC. Enter in the ip address etc and connect.( It requires to be entered manually) Problem will be solved.

I had just the same problem with s8 plus and s7 edge(after updating to android 7.0), it kept saying "internet may not be available", I changed the DNS to 8.8.8.8 and tue problem solved. Go to SETTINGS》WIFI》SSID》MANGE NETWORK》change the IP SETTINGS to STATIC》then change the DNS1 to 8.8.8.8 hit save and you are good to go.

I have same problem and it is very annoying. I got 2 S8 plus and both have the problem.
There are 3 WIFI Router that covers my house. I have problems saying internet might not be available every time I connect. This is very annoying. Other Phones in the house like Iphone do not have the problem.
What I noticed is that the IP range of my router is:
192.168.1.1
But my S8 says he is connected but the IP is
192.168.0.100
Anyone have same problem?
Thanks!

I found a quick work around on how to fix this temporarily until Samsung issues a patch.
just turn off 5ghz SSID broadcasting and you should be ok for now.
here is a quick how to video i made on just in case.
https://youtu.be/Nu5FjDPLn-M
I'm having a very similar problem with my home WiFi and my Verizon S8+ I bought from Samsung's website. I've tried switching from DHCP to static and entering all my info. No luck. I've also switched my dns1 to 8.8.8.8 and dns2 to 8.8.4.4, and my WiFi router is set to 2.4ghz only. No success in resolving the issue. Currently my phone will show the "internet may not be available" with the added exclaimation point for a few minutes when first connected, then the exclaimation goes away and I'll have regular full speed internet for around 25-45 seconds before it goes back to a non-internet state. Any suggestions?
Try changing in your router the security setting. If your using WPA2 AES/TKIP, change to just WPA2 TKIP and see if this works for you...
I was having the same exact issue for months. I changed to TKIP only and have been rock solid ever since. No more ! at all... I'm gonna switch to just AES today and see how that works.
Changed to WPA2-AES and within the hour had ! back and no internet. Went back to TKIP and rock solid again. Looks like a possible bug with AES to me. Sticking with wpa2-tkip setting for now.
I'm having this same exact issue.
Anyone who knows what to look for to fix this, what info or files do you need from me? I'm at the end of my tether with this ****
I am having the exact same issue on my galaxy tab s2, even on the replacement. Due to the being such an intermittent problem, it wouldn't do it when Samsung support checked it out...
This happens on both 2.4 ghz and 5 ghz frequency for me. I've tried downloading a wifi fixer, I've reset network settings, and turned off nearby device scanning. I've also tried doing what a forum suggested by changing the ip settings from dhcp to static but it wouldn't connect to wifi at all. Not sure what else to try...
I read that it may be due to nougat 7.0 software. I was suggested by Samsung to first put the tablet on safe mode (this disables third party apps, and would reveil if an app was causing the problem) but the problem still persists. Also did a hard reset on the first tablet I had but it still done the same problem...
I always thought that this was a is problem in 7.0, and was addressed in 7.1. Hopefully, when the next major update comes out, this issue will be resolved.
Oh come on Samsung!
It's been 4 months since the first post and still no solution.
And it's a basic wifi connection!
Internet may not be available! = Samsung may not be available
Heya all. First post I guess
Edit: Gah it was the second. I have to controll myself better and not spam.
So I had the same problem and tried more or less all.
My "solution" was to disable the firewall on the router which means some settings/security there was triggered. My guess is that it's the "Smart Network connection" that trigger it if the phone have both poor Wi-Fi and 4G. It then jumps back and forward = firewall detect strange behaviour and block. That's why there are so many strange "fix" related to the router - hidden network - no security - disable 5Ghz and so on.
Can someone please test asap as I have a plan But if it's not this to test

Elephone S7 wifi disconnecting and Reconnecting issue

hi, I have an elephone S7 4G 64gb version. I'm having issues with a wifi network at home. It keeps disconnecting and reconnecting. I've searched around the internet and have tried all the possible solutions but no one works. The problem occurs only with the home wifi though, it works normal with office wifi and portable hotspots. Seems like there is some compatibility issue with the router at home (TP-Link Router). One solution that works temporarily is the cache clearing in storage settings. When it is done, the wifi keeps the connection for about 15 to 20 minutes and then again the same problem occurs. I want to know if anybody else is having this issue and would installing a custom ROM resolve this issue or not? I also applied Wifi MAC fix to the current ROM, would the custom ROM keep that fix?

WiFi issues after Feb Update (OREO)

Hello everyone,
I have a TA-1039 and I've noticed that the WiFi is not working properly.
Before this update, I use to have a perfect strength and speed from both home and work and now it's a very poor connection.
Do you have this issue with your device? Could you help me how to fix it?
Thanks in advance.
Try disabling Bluetooth scanning in Location settings. It may interfere with some 2.4G channels.

After updating to Android Oreo 8.1 , Make a backup to your device , just the photos and videos and contacts , then reset your phone and every thing will work properly , i have a Nokia 6 2017 and it works fine after resetting , because i had the same issue which is caused by the update somehow.
I had the same issue
I bought a nokia 5 & 2 weeks later
The wifi connection was dropping everytime even when i was close to the router
I read in other forums by changing the multimode B/g/n in the router fix it
So i put B/g only & the wifi icon bars increased 1+ & doesnt drop anymore

oneplus 8 pro wifi/bluetooth issues (with a tmobile sim)

So I may have come across something that may help someone else out as well...
Recently (as in less than 15 days) purchased a oneplus 8 pro from oneplus.com. When I first got it it was on android 10 and I was not able to connect to either my 2.4ghz wifi or my 5ghz wifi using WPA2. I had a oneplus 7 pro previously that still connects without issue. I had read elsewhere that the open beta was better so I tried that and it indeed was better but sometimes though I was connected to the wifi, no traffic would travel over the network and it would stall to the point that the only way I could do anything internet or network related was to go to my cellular data. I did the 'device mac' as opposed to random mac and that helped for a brief time however that even cause the same stall/lack of response issues.
Since I don't have much for 5g cellular where I am, I changed it to only look for 4g....still no improvement. On a whim, I disabled any and all security on my 5ghz wifi and low and behold I could connect. I wasn't about to leave either of my wifi networks wide open but also remembered the network I connect at work is also not wpa or any sort of protection so theres a hint as to how to 'fix' these issues. I then read someone about the possibility of having special characters in your wifi password can cause issues. I removed the ! in my old wifi password so it is now alpha numeric and have had no issues with my 5ghz wifi network. I have been able to stay connected with my 5ghz wifi WHILE bluetooth has also been abled and the speeds are roughly normal.
Try at your own risk but in summary:
1. upgrade to the open beta 2
2. disable 5g cellular connections
3. connect to your 5g wifi and make sure the password has no special characters in it as well as use device mac NOT randomized mac
4. perhaps success
With all the above being said, I do still intend on sending this phone back in hopes that I got a dud unit but I'll admit seeing these results makes me feel like its more of a software issue and certain incompatibilities with certain routers.
Just dropping what info I have discovered in hopes it helps someone out there...I would not normally endorse using NO password on wifi or a weak password, but for this phone it may be a requirement at least until the updates can come into play.
Thanks,
E|
I am backing everything up to go to Android 11 tonight, and I switched to a new WPA2/WPA3 router here, but my password has no special characters.
On Android 10, complete nogo, as using WiFi calling with a BT headset on 5ghz slows the network down so much, the other person can't hear you (no upload bandwidth).
I'll let you know how Android 11, OB2 works out for me.
If there are issues, I am going back to the OnePlus 7 Pro and selling the OP8 Pro.
Since I have not been using WiFi, I blew through 55Gb of data this month already so am subject to throttling, thanks OP8 Pro

You could try om a different router of someone else to pin point out if it's your router yes or no.

I did upgrade to OB2 a few days ago and wifi is generally better. But VOWiFi never works with a bluetooth headset - the other person can never hear me.
Also when streaming over WiFi the connection drops or stalls and causes rebuffering. I have confirmed these behaviors with 3 different routers.
Can anyone on TMobile (USA) confirm working VOWiFi while using a bluetooth headset?
Also 4G and 5G speeds slow down when on a call using bluetooth.
Maybe this is all due to qualcomm 865 chipset issues as the galaxy S20 users are having similar issues?
I had faced lots of stability and speed issues on the 5gz band. Received the OS11 update today and my issues seem to be resolved. So far the 5gz connection has been very stable, lightening fast speeds.
