I have Verizon Galaxy Nexus running on 4.0.4, rooted. The mobile hotspot SSID is set as "myWiFi". The problem is, every time I run mobile hotspot on my phone, the network name in the laptop gets identified as myWiFi 1, myWiFi 2, ... with the # going up by 1 every time I run mobile hotspot from my phone.
I have no clue whats causing this. The SSID is still the same - "myWiFi" but the laptop keeps appending a new number to the SSID every time I run the hotspot. Please suggest ways how this can be fixed.
ssid renumbered each log on

I'm having the same issue and it began with the the 4.04 update. In addition I lose the signal more often since the update. I've searched for answers, but no luck. I even called Verizon and Samsung... their only response was to send the phone back. That makes no sense given that it worked fine before the update.
My boss's Galaxy Nexus is doing this too. It's currently running 4.1.1 on Telus. The phone also occasionally disconnects or provides no internet access while tethering - it's very frustrating and seemingly random. Has anyone fixed this since your post?
Hello everybody, this is my first post here but I have been reading the ViperS threads in the development forum since version 2. Awesome rom, I really like it.
However, I have encountered an issue with ViperS 5.1.0 . I would like someone else confirm if this is happening on his sensation too (with ViperS 5.1.0), because its a very annoying bug, and a potential security flaw.
A few days ago I installed ViperS 5.1.0 (from full wipe and no restoring of backups, clean install), and shortly afterwards I noticed that my home computers in my LAN (ethernet and wifi), where having some kind of little micro-cuts in communication with the internet, especially noticeable with google and youtube autocomplete feature and things like that. The communication completely stops for a few seconds, then resumes and works perfectly until a couple of minutes (sometimes less), and it happens again.
I checked my network with a packet sniffer, and found the culprit to be the Sensation. This is what happens:
I have wifi set to always active on the phone and, when the phone is left suspended with screen off, after a little while it begins to send bogus ARP protocol broadcast packets announcing that it has a random (and incorrect) IP associated to his wlan mac. It repeats it again with several other random IPs over time, and sometimes it also says via ARP that it has the same IP as my home router. In that case, it causes all computers and devices on the network, to try to access the internet via the Sensation's wlan card mac, which obviously fails, causing the micro-cuts. After a few seconds, the router sends the correct ARP information and the computers can access the internet again. This is very similar to an ARP spoof attack, but I can't see why the phone is doing it.
It's only happening with ViperS 5.1.0. I have tried disabling ad away and also tried to connect with a fixed IP instead of DHCP, but it keeps happening.
I have attached a screenshot to show the problem.
PD: On other subject, the wifi is buggy when changing access points in the same WLAN (I have 2 APs at home), it turns off, activates mobile data, and then turns wifi on again, taking a long while to do it. In ViperS 3, it just went from one access point to the other without disconnecting. This is a secondary thing, I can live with it, but I thought I should say it just in case it's a easy thing to solve for the devs.
Thanks for your time! I really appreciate your work. :good:
I have been trying to do a packet capture in the phone, and tried to find something in the logs, but I can't see anything. Could this be related to the wifi drivers? Since ARP protocol is in link layer, I can't think of anything else.
Also the other day I connected to a wifi network in other place, and it completely crashed the router, no one else could connect.
@ivicask , I would really appreciate it if you can have a look at this. Because of it, at the moment I'm using mobile data only even at home, and I'm going to use it up pretty quickly
Thanks in advance :good:

I have been using ViperS for a while, and I it certainly isn't ARP poisoning the network.
Try setting a static IP (set it to that alloted by your DHCP) and see if the issue persists.
Happy to help.

That's the first thing I tried, it didn't help.
I have googled it and seems there are some problems with the ARP offload feature in the wifi chip drivers, and several phones have suffered it, the nexus 4 and some HTC devices. A lot of people have reported it in the google code forums.
The thing is that it didn't happen to me in previous ViperS 5.0.0, so something must have been changed in the rom that it's causing it. Do you know where I could look? Maybe it's just something wrong in a config file and can be easily solved.

While I may not know I shall still try to help once I am home I will quote your post into the correct ROM thread to see if the devs/power users of this ROM can help out

ok im posting it now, can you get a logcat to supply to the devs please?
Yes i saw this, but as only person with this problem, i didint investigate. There can be many reasons this is happening to you, but most likely its problem in your own network/routers. My suggestion is first try updating your routers firmware, if there isnt new firmware, just try resting them to factory default and re configure them. I have actual experience with this, my DIR-655 couldn't connect in wifi N mode until i reseted it.
Also HTC ONE users had problems with Dir -655 where it would reboot if HTC one would connect to it (Firmware issue).
Also from your pics i see "duplicate use of 192.168.1.1", are you running 2 routers on same network with same ip address??Than this is the reason of your problems, you cant have 2 devices with same IP in same network, even worse will happen if those 2 devices are actual routers, or even worse if both of them are running DHCP.So re-check your network, make sure only 1 DHCP is running, and there are no devices with same fixed IP address.
Also here are to 2 tests for phone with different wifi supplicant versions, try them ONLY after you make sure your network is fine.

EDIT:About wifi switching, same thing happens on my ONEX+ ...

Thanks for your answer. The "duplicate use of 192.168.1.1" is exactly the problem, I know that (I am a telecomms tech, I know how this works )
The matter is that the device that is claiming to have the same IP as the router... is the Sensation! See the "source" column in the pic.
I have only one router. Everything is properly configured in the network, the issue only appears when the sensation is connected to wifi AND with screen off. Then it starts sending the false random ARP packets.
Apart from the "router impostor" packets, there is also the problem that over time the other random packets will fill up the ARP tables in the router memory, causing it to hang, although this hasn´t yet happened to me.
In the threads I saw in the google code forums, people reported the same thing for the nexus 4 and several newer HTC devices with the same broadcom chip, (which also caused notification delays) and said that it disappears when disabling "wifi optimization" (with the rise in battery drain that it implies) , which looks like a bug somewhere in the wifi drivers. Unfortunately, disabling that option does not change anything for me.
This has started happening in 5.1.0. Never had such a problem before.
Thanks for the files, I will try them and report results.
Except for this and a weird bug with h/w accelerated videos screen corruption when free memory less than ~90 mb, the ROM is absolutely awesome :good: . It feels much faster and lighter than previous versions. You devs are doing a very good job :good:. HTC should hire you!
OK, problem solved. The test2 file solved it.
With test 1, it stopped sending random IPs in the ARP packets, but instead claimed to have 0.0.0.0 always, and not the correct IP. Also, it couldn't see channel 13 which I'm using on one of my access points (probably region was set to USA in this file).
With test 2, the ARP packets report the correct assigned IP (via DHCP and fixed), it can see all the wifi channels, and everything works perfect. It also appears to be changing from one AP to the other without disconnecting the wifi. This is the correct way it should work.
Still don't know the need to send the ARP info each 15 seconds , but at least now it's correct and there are no problems.
Thank you very much for your help @ivicask , I have seen that the wpa supplicant in the files you posted has an older date, is it just an older version or have you changed something in them also?
Will you include this fix in the next version of ViperS?
Thanks again :good:
Same for me. Killed my router. Especially if downloading at high speed. My router went upp and down. Now I have on other phone and my senny runs stock. No problems att all.
Flashed Viper to check 3min then router died. (it reboots)
Thanks
I couldnt neither write in the original post. By the way, i have the same problem with my wifi conection.
Now i solved it with Test2.zip. I have european wifi too and my router see fine now.
Thanks a lot for this rom and the help.
I didn't notice any particular issues with my WiFi, but I was having the disconnecting behaviour when switching between APs.
The Test2.zip solved this.
More, I tested the received power with Netgear Wifi Analyzer in an already tested place in my home. After applying the Test2.zip it looks like I gained ~10dBm. Maybe it's just something casual, but I wanted to report.
Last. The wpasupplicant file in the Test2.zip has the same modification time as the one in ViperSC2_3.1.4, so I think it has been taken from there
Good job anyway :good:
Hi guys. A couple of days ago, I unlocked my Samsung S5 Active (originally from AT&T) and connected it to Metro PCS. Everything went smooth and great . I have the "UNLIMITED", as they say, data plan. I take advantage of the HUGE 5 gigs of blazing speed through hotspot they give with it whenever I have the chance.
Now, 2 days after I connected my phone with the new network, the only glitch that I have encounter so far (besides wanting to delete all AT&T system apps, but can't without root) is that my hotspot from one minute to the other stopped communication with the world. It was working like a champ today, connected to multiple devices (nothing big, just driving around playing Pokémon. The devices connected were extra cellphones with no mobile data). It happened soon after me attempting to sync my Samsung to my cars bluetooth during a phone call. After syncing my Samsung, I activated the Smart Lock in my phone to my car, with all of this happening while the hotspot was on. I'm assuming, that somehow it's connected to the problem? Idk...I've tried googling about similar problems but have come up empty. I checked and rechecked my APN settings, everything is working great. Paired my Bluetooth with the devices that were previously connected on my hotspot, and they paired flawlessly. The phone is working pretty well, although my networking bars jump up and down in areas that my LG K7 always had 5 bars. It's only when I turn on my hotspot, my phone acknowledging the hotspot is up and running, that everything goes down the drain. Not one device can locate my phones hotspot.
The one thing I did notice was that when I ran a system info app, is that it showed my mac and ip address but the SSID said <unknown SSID>
SOMEONE HELP ME PLEASE!!
GUYS....UHHH....YEAH. Found the problem. Somehow or another, I checked the box next to "Hide my device" in the Configure Hotspot setting. Sorry for any inconvenience my bruthaz.
On a different note, does anyone know if it's possible to edit our profile name? My smart self left out the "R" between the E and the Z on my profile name
Hi
My phone upgraded to Pie 2 days ago and since the update my WiFi no longer connects. My phone can see the various networks and when I try to connect it is like it is stuck in an authentication loop and acts like the password is incorrect. I have entered the password multiple times and even changed it too. It sits in the saved networks but will not connect. I even fiddled with the WiFi turns on automatically settings and it still doesn't work. I have tried everything even factory resetting my phone, which has been a nightmare because I lost a heap of 2FA codes with my authenticator. I have reset my router, changed SSIDs, passwords etc. Basically everything I can think of I have done. I have raised the issue with HTC and they have asked me to do what I have already done but in the meantime, while I await a response from them for my next course of action, I am wondering if any of you guys know of any issues where the WiFi doesn't work anymore. I am currently using the internet on my mobile network but I will probably burn through the data before the month is out so I am really keen to get my WiFi working again as it's going to cost me a fortune otherwise.
Thanks in advance for any responses that I may receive
Solved
Ok I fixed it. It was a weird solution all I had to do was disable my password on my network and it connected fine. I then re-enabled my network password and entered the password on my phone and it worked. This was such a frustrating issue and I don't know why it wouldn't work before. I went through some pretty drastic measures to sort it, but now I know for next time to try this. I hope this helps anyone else out with a similar issue
I bought a Galaxy Express 3 (sm-j120a) on Ebay (new condition) to use as a backup phone. I began the setup process and tried connecting to my WiFi. I put in the correct password but it will constantly cycle between showing "Connecting" underneath the SSID, then suddenly the SSID disappears, then suddenly it will reappear and show "Connecting" underneath, etc. It will do this indefinitely and will never connect. If anyone has experienced this issue before and knows how to fix it, I would greatly appreciate some help.
One thing I haven't checked is whether I could update the software of the phone to the last available update. I wanted to hold off on putting in my sim card because I have a nano sim and I think the phone takes a micro sim and I don't have an adapter yet. Is there a way I can download any available updates to my computer, then send the update to the phone via a USB cable?
Thanks!
i ran into the same thing a while back with an old android phone, a samsung j120a. one day its wifi stopped working with the att modem i have, a bgw210. behavior was the same as what you described. every other wifi device in the house worked fine. tried every standard trouble shooting thing you find when you search this, including factory data reset, nothing. got hold of another phone same model... it also failed to connect to wifi on this modem, same thing.
the answer-> i resorted to playing with the wifi settings on modem, and found that the problem was with the wpa version setting- it was set to wpa 2 by default when i found it. i changed it to the setting that accepted both versions 1 and 2, and the phone's wifi now works again.
i assume at some point att updated this modem, and one of the updates was to change default setting on the wpa version, probably because wpa 2 is supposed to be more secure than wpa 1
just replying because i hate searching stuff like this and finding nothing but people asking roughly the same question without getting any answers. hope this helps somebody searching this in future
