Wi-Fi connection Problems Galaxy SIII...Help Please!!! :) - Galaxy S III Q&A, Help & Troubleshooting

Hello
Im a proudly owner of a S3 and a GNexus and I have some problems regarding Wi-Fi, I know that this is not an S3 problem but its and android problem but perhaps someone can help me in here..
the thing is, I have two routers in my house, one is the master one for cable/internet company and the other is and range extender to expand the signal of the wireless lan....
every morning, when I wake up, if I go to the floor where is the first router both my S3 and Gnexus connect successfully to the wireless network and evevyrthing works fine....however if I go to the floor where the bridge/extender is located, both phones detects the wireless network, however can't connect to it, on wireless settings says...Obtaining ip address...and stays there for ages...and nothing...cant connect...for me to connect to the bridge, I have to restart the bridge and both phones connect immediately...
please any ideas??
thanks and best regards,

Is it password protected? If so try making it 'open' or change the encryption type.

Hi,
first thanks for the quick reply,
yes the network is password protected...I changed the encryption type for the WPA not the WPA2 and the problem still persists...
the thing that kills my brains is that, to connect to the bridge I must restart the the access point every morning,....
thanks

Do you have DHCP enabled on the 2nd router?

yes, I guess so....., should DHCP be enabled or disabled?

sorry but this situation is driving me crazy.....
I cant connect to the brigde/extender network right now with both my android phones and android tablet, however with my laptop running windows 8 I can......
wth??????
this is so frustrating!!!!!

Are you sure the second device extends the main access point and not just create a new WLAN?
Have you updated the firmware of both devices?
What devices do you have?
Am I understanding correctly that your laptop does work even though both Android devices don't (before you reboot the extender)?

Nope...its not creating another wireless lan... it extends the main plan correctly cause my laptop connects perfectly to the Wi-Fi from the extender even prior to the restart of the extender....
The devices are...main router from the ISP- Thomson
Range extender- tp link 701nd

Both have latest firmware? Might be a bug in the WiFi driver of the AP/ROUTER... or it's in Android.... you will need to test by trial and error I guess...

Ok..
Do you guys know anything if I must have my IP static or dynamic?

Dynamic would be the friendliest to work with... you could try if it's a DHCP issue by setting a fixed IP when the problem occurs, but I don't think it is.

This is not a problem with the phone(s)....is with the router config. Contact the manufacturer for further assistance...

If you got a router and a range extender, there's nothing you need to fiddle with because the range extender will just Relay DHCP requests between client and master router.
Two routers* pushing out IP addresses is a no go, there will be a conflict in your scenario, and all range extenders will of course take this into account.
If you had two "real" routers*, it would still be possible to set everything up, although then there's a lot to take into account.
* Router is a inaccurate term used for the consumer grade combination devices. They're in fact a router, a switch, and a wireless access point bundled in a neat package. Sometimes with a xDSL modem or something on the external interface of the router.

Try setting the IP to static and more important, try giving it a default gateway to the routers IP. That should make it easy for your phone to directly look for the gateway it is looking for.

I have three routers, one main, one extender, one repeater (creating a whole new network for other building). Both main and repeater are the same network. All is config as per DD-WRT documentation. All three have latest DD-WRT.
After trying many things, all I can say is the (or mine at least) S3 always has trouble when many APs are nearby. I don't use VOIP because of that (it could disconnect at any time).
Next step on my list is to have 3 different SSIDs (only two now) and try using tasker to debounce the wifi switching (if that is even possible).

Hero not recognizing wifi router

Hi all, this issue is driving me to distraction! I've changed my internet service provider and they have sent out a new router (d-link DSL- 2680) to use and since hooking everything up my Hero no longer recognizes the router i.e. I will do a wifi scan and it will display a list of all the other routers within range but my new router will not appear on the list?! So frustrating as I use my Hero as my main internet connected devise at home! Any suggestions or help would be welcome! Thankyou!

hi, did you fix this? i have the same problem
cheers
Maby your router isnt broadcasting it's SSID ??
Hello!
I'm new here as u can see. But It's funny that I got the same router DSL- 2680 with the same issue.. My Hero is running SHPONGLE v3.6 (what a great rom!) :good:
I have three laptops which are using this router with no problems at all. Hero just doesn't like the DSL?
Problem solved
What I did: Went to routers setup. --> Wi-Fi Protected setup --> tick off Enable
It's working great now. I hope this helps u a bit, stevieg73.

Ugh...Wifi Issue (Yes I read EVERY wifi post) Bounty for fix!

Ok, I have read every single thread (to my knowledge) about the Wifi Connect Issue. I have tried all the manual tricks (changing router settings / channels / changed SSID / passwords / Security / reset router to factory / airplane mode / factory reset on GTab, etc) and STILL can NOT connect my GTab to home router.
I CAN connect it to my Galaxy S Vibrant Mobile AP Wireless, I can also connect every other device to my Router without issue. (Vibrant / Nook Color / Archos 70 IT / Wireless Printer, etc)
I'd be happy to toss a donation tip to whoever can help me with this...it's truly EFFIN frustrating. I can get speeds of 12-15MB/s on all my other devices off the router wireless connection. With the GTab I'm just stuck in a cycle of "Obtaining IP Address...Connecting...Obtaining...yadda effin yadda"
Running VEGAn-Tab 5.1
BTW - bought it earlier tonight...totally lovin this thing, beastly! Compared with my 4 other Android Devices, it's nutz! Thanks to all of your great info and ROMs!
***SOLVED 1/10...Bought New Router & working fine now!!***

The usual stuff...Wi-Fi toggle / Network Notification toggle / Add wifi network
Once toggled on...several networks show up...including my Router Connection
So network and and gtab wireless are working.
Has to be a setting somewhere thats off.
Changed everything again...even matched the settings exactly the same as the settings on my Android Phone...no luck.

Yep...that too. Beginning to think GTab doesn't like my router. I have a Belkin N1 Router if anyone else has the same and could advise.
Try flashing pershoot's latest kernel. It has a VERY updated wifi driver.

Only other thing I can think of is wacked out router, or maybe some mac filtering, upnp, or other "helpful" crap on the router that is causing it to not connect. I don't own any Belkin devices. I stick to Linksys or D-Link...
Sorry, man...
Have you tried connecting to a different wireless network? (sorry if this was already suggested.) Coffee house or any other company with free wireless, maybe at your job?

Connects to my girlfriends belkn n600. But thats a brand new router just installed last night. 69 at best buy
Couple of thoughts:
you may just have a defect. it happens. can't hurt to return for another one
not sure what type of router you have, but most if not all allow you to look at the event log. from there you should be able to tell why it's not being assigned an address (i.e. p/w wrong, range not avail, etc)
is your router restricting the type of access? (i.e. "b" but not "g" or "n")
didn't see in earlier posts, but have you been able to connect to any wifi networks? (i.e. public ones, or a mobile device's hotspot)
1) Is your router set to only serve out a small number of IP addresses via DHCP? Perhaps the available IPs have been used by other devices
2) I know you did a factory reset, but make sure MAC filtering is not turned on. Not sure what the Belkin defaults to but should be off unless you want to add the MACs manually to the whitelist.
3) If your SSID is showing up in the Wireless list on your GTablet, try deleting it (long press, then Forget) and then re-add it...You may have "cached" some old settings from your previous configurations...

[Q] Multiple Wifi Configuration

Hi' all.
I use very often 2 Wifi networks. (Home & Work)
The problem is, the home network is configured so that a new ip is assigned each time i connect.
The work network is configured to use a static ip.
How can i configure the phone (Galaxy S II) so that i can access both networks without having to change all settings each time i connect to a different network?
Btw, i know all the parameters to configure each one correctly, i just can't make the phone remember the setting i want for each specific network.

Thanks for your response, but that's not really a solution for my case. I am new to the Android scene, so i thought i was being ignorant, but i realise that's not the case. Really odd android doesn't have the option for profiling wifi's. Nokia have it since they came with wifi conectivity.

WIFI issues, new device

Hello wondering if anyone can help.
Bought the device yesterday, galaxy player 5.0
The only way I can connect to the wifi is if I disable WEP and have the router open.
When I use WIFI, either from the cell phone or my home WIFI using WEP, the device is stuck in obtaining IP address, as soon as I remove the WEP and have the router open, it connects.
None of my other devices have this issue, only this one.
Any ideas?
or
Should I return it?
Thanks.
I found that if my router was broadcasting its SSID my 5 would connect, if it was hiding the SSID it would not (just sat there searching for IP). Maybe that's the problem?
Mine has problem too on my belkin54g (open config), connect and disconnection all the time pretty annoying, i really hope there will come a fix out from samsung since it came with 2.3.5 update....
Thanks!!!
Thanks guys got it working.
Changed password on the router and did a reset to it.
Seems that did the trick.
Almost returned the player.
And the worst is that I had already installed a shield for the screen, 15 bucks!!!
Anyway, thanks for the response!!!
Hidden SSID need patch for YP-G70
Just install HiddenSSID Enabler from market, it'll work for YP-G70. You need run it once and get your hidden wifi connected, then can uninstall it. Looks like it is just a patch but really works.
I was under the impression you could use a hidden SSID under stock 2.3.5. Under Wifi Settings, there is the "Add Wi-Fi network" option, and it looks like it can be used for hidden SSIDs.

No, it won't work coz hidden SSID not supported by GB.

Try using WPA instead of WEP. WEP is ancient, and some newer wifi chipsets don't interoperate well with it because it's so old and it's been HIGHLY recommended to ditch it on routers for at least 5 years. WEP was known to be insecure almost a decade ago!

Someone correct me if I'm wrong but it seems like I remember reading a few years ago that hidden ssid's were not part of the 802.11 b,g, or n specifications. I thought that while a lot of devices had that function, it wasn't exactly "compliant".

Yes, that's true. I haven't seen any android smartphone on GB (don't know what's in ICS) can connect hidden SSID unless apply the hidden SSID Enabler patch. However, iphone / ipod has no problem.

I am constantly losing my connection with wifi, i got samsung galaxy player s wifi 3.6
wifi disconnect/reconnect fixed
On my 4.0 US, the wifi would disconnect and reconnect constantly. To fix it, go to ur network (on windows go to start and click network or type in ur IP address) and go to LAN settings. Change the dhcp lease time to 2 weeks or anything bit forever. It resolved my issue completely

Question Bypassing hotspot/tethering throttle speed on n200 5g

Got a free n200 through tmobile to use as a hotspot device for my pc. I was previously getting the job done by using a galaxy note 3 and setting my pc's ttl to 65 but apparently that doesn't work with the newer phones.
I did some searching online and haven't been able to get a definitive solution to bypassing the hotspot throttle, as people seem to have varying results.
Had a lot of issues with PDAnet+, so it's definitely not a long-term solution for me.
Just sent an unlock request to OnePlus, hopefully by next week I'll get the unlock file and I'll root the phone. I'm assuming that rooting the phone will expand my options for what I want to do. Anyone have a solution that worked for them?
Yo, it's like dns hijacking, in fact, this is what you have to do to bypass this.
I'll paint a scenario, see what you make of it...
I plug my sim into a wifi router, in the control panel of this router, I set the wifi to use the 2nd ip, (yes, all isp's actually give you 2 ip's, one that is public, one the isp use's to spy on you, and the one you see in your ethernet card, usually 192.168.1.1.
Your wifi router runs adb, so it is on a different network, being 192.168.0.1, if you set your connecting device to your public ip shown by the router, and nxbogus domain your isp's private number seen in the router, (usually 100.whatever) and their dns, then set your prefered dns in the connecting device, you will bypass the throttling, but you will notice something else...
They throttle you by lowering your phones coverage lol...
Notice in your wifi setup pages your signal will drop from say 75% to 25%, and if you check the config logs, you'll see your limited 90% by the isp..
Yup, I'm isp level in this department..
didn't understand half of what you said. can you break it down a lil bit more?

yea i'm using easytether rn, very similar to foxfi and pdanet+... not a permanent solution however, as it tends to randomly disconnect and i often get kicked out of games due to "network lag". Speeds are exponentially faster than the throttled hotspot, however, so i wont complain.
still, would be nice if there was a solution to this for the native hotspot/tether features... tried everything with apns and changing the ttl on the phone but it didn't work.
looks like someone found a solution for the moto g 5g here, maybe i'll try to implement this for the n200, could be a possible workaround.

moto g solution you posted requires a special kernel. usb tethering through PDAnet+ paid version works fine, the key is you dont enable it thru the native tethering, instead enable USB tethering through the PDAnet app and leave the phone on charging mode so it can make a ADB connection. Make sure ADB is working and you can establish a working adb connection from PC to phone first prior to attempting to tether since it will use ADB. i get full speeds tethering using the paid version.

yeah i've been doing this via easy tether, gets the job done for the most part
For me, PDAnet has low throughput while EasyTether runs full speed and can be used with OpenWRT. They both disconnect randomly though.
No reason to deal with that if you have root. AdGuard+VPNHotspot+noprovisioning is easy to setup and works fine for most networks.

Only connection is WAN to WAN!
Ok, first, I use an lte wifi router, enter gui, goto lan, change router login ip to any ip not 192.168.1.1 or 192.168.0.1, the latter is hidden in router, but when trying to connect 2nd router, using this ip, problems appear, because the 1st router has adb enabled due to the lte section of 1st router being android 6, and uses's it.
So in effect, I set 1st routers address to 192.168.1.5, 255.255.254.0, 192.168.1.3 ie, this is 1st router login address. In the 2nd router I set mac address of 1st router to use 192.168.1.3, having been set in the 1st.
I do this because if I set 2nd router to match 1st routers address, the 2nd router auto changes address, when plugged in to first, and the 1st router changes too.
So now that you can goto 192.168.1.1 in 2nd router with 1st plugged in, try 192.168.1.3.
First part over, now the tricky part...
Disconnect 2nd router (this Will become your MAIN router)
Start 1st router with sim in, only to obtain public ip, because you need to set this ip in WAN of 2nd router. If your ip changes every reboot, you need to check public ip from first router match's what you set the wan ip to in 2nd router.
Now when you are in 1st router's network/lan settings, look for option to use 2nd ip. enable it, in the ip box put your public ip, ie your internet ip, and remove all access to anything else, including disabling wifi, both 2.5 and 5g.
So now plug in 2nd router WAN to first routers WAN.
Go into 2nd router, and block the PRIVATE ip seen in 1st router, the ip the isp shows you, and NX=bogusdomain your isp's private dns
In your WAN page of 2nd router, set preferred dns.
Voila.
70-80% increase in response.
The hardware method to block dns hijacking
Ps any reboot of the first router will change its ip due to being lte, so remember to check 2nd router match's after any power outage...
