[Q] Wifi problem [can't see milestone's tether network]

Hi all,
I'm tring to connect my galaxy tab to internet through wifi tether on milestone and the tab can't see the milestone wifi network.
I know for sure that milestone's wifi tether works fine because I can use it with my laptop.
Anyone has the same issue?
How can I solve?
hi
i used the wifi hotspot of my desire and it worked great.
what i miss is the capability to find and connect to Ad Hoc's
(they just dont appear in the networks list on my tab)
maybe the milestone is creating a ad hoc.
Yes it is..
How can i make a different network type and fix it?

wi fi router of winmo phone not being seen on galaxy tab

I have a tmobile galaxy tab running on Roto JMI v2, and I dont have any cellular/data connection now. I have a winmo phone where I have wi-fi router installed which has internet available.
My galaxy tab can never see the wireless network which is being broadcasted by my winmo phone. I know my phone is doing the right thing as I can connect my laptop to it and surf the internet, but my galaxy tab does not see it.
I tried adding it manually, but still no connection.
Did anyone face this problem? Is it something to do with winmo phones?
I bet it's an ad-hoc network, you'll need to edit wpa_supplicant.conf
Not Winmo specifically, but ADHOC networks in general. Had to replace the WPA_supplicant with one that would allow adhoc connections. I've done that and it works fine. Might be the same issue.
There is a topic on this board about connecting your GTAB to a OG Droid or Droid X and it has the links to the file and the process...

So who wants to help me with a problem :(

I've killed the internet trying to find people who will help me but I can't
I installed Gentoo on my Galaxy Tab 10.1, but how could i set up wifi for this network?
My network name is BK1D7, and it is unsecured so I have no passkey set. (I had one, but later disabled it). I tried to edit /etc/conf.d/net for wireless, and it seems to attempt to connect but then fails. How must I set up etc/conf.d/net and wpa_supplicant.conf ?
(*this is gonna be myTouch 4G related in about 40 minutes when I take a photo my Galaxy Tab using my myTouch 4G on ICS ;D provided someone can help me *)

[Q] Major Wifi Issue!!

I am having a major issue with the wifi on my i9500!!
So I bought this phone from a guy.. he said the phone is never used and by looking at the condition, it seemed he was telling the truth!!
So anyways... I buy it, come home and I double check everything on the phone and also try my wifi network... I couldn't connect to my home network!! Its the same network that I connected my macbook, my previous phones (s3 and note 2)... every other device works fine except this s4!!!
So i thought the phone was faulty, and thats the reason the guy sold it to me!!!
So... I borrowed another i9500 from a store and asked them i need to check if my home wifi works... and again same thing.. It doesnt work on my home network!!
I also tried going in yorkdale mall and checked my girlfriends note 2 and my s4 and tried connecting to the open network!!
NOTE 2 connected in 15-20 seconds.. while the s4 never connected and kept on saying "acquiring IP address".. I tried connecting to my home network by doing "Advanced Connection" and manually adding the IP address.. IT CONNECTS! But i cannot do anything.. theres no internet access!!
Now im confused as to if my home network is the issue here, but if that was the case.. why did my girlfriends note 2 connect to the open network at yorkdale mall while mine didn't connect at all!!!
CAN SOMEONE PLEASE HELP ME!! I USE internet by this company called "CIK"... yeah my dads trying something new... we definitely get more speed on every device!! so its definitely better that way! but the only problem is i cannot connect my s4... Now i dont know if its the s4 itself, or my home network!!!
I need wifi... yes i do have 6gb data plan, but then i'll be going out of country soon and i'll be needing wifi for sure!!
sorry for the confusion... but all i need is to get my wifi working.. or if the device's wifi is faulty, how can i find that out for sure!
any help would really be appreciated!
thanks in advance people!!

this happened to my older brother's s4 too we even sent it back to our retailer thinking its a factory defect but it turns out to be router incompatibilities. I suggest replacing your router to a preferably future-proof one, the ones with the ac standards. Routers such as netgear or asus are some of my recommended ones

if you use a dsl connection use a dual-band router with adsl support such as these products.

Wow thanks.. I guess it is the router then.. BUT the thing I wonder is why all the devices still work fine and just the s4 doesnt seem to connect!!!
Or is it all the samsung galaxy s4s and they have done some tweaking with the settings... no idea..
but its good to find out for sure that its not the device!!
I shall try connecting my phone at few of my friends place... + at local starbucks/tim hortons... it better connect LOL!!
Thanks anyways
ok, happend to my sisters s4 today, when i got it for her because she liked mine so much, anyways, niether my phone or her connects to Her home router, but her old iphone 5 does. and her husbands s3 does. so i replaced there router with this one
http://www.tp-link.us/products/details/?categoryid=238&model=TL-WR941ND
and i called the SP for her network information. and programmed the new router with this PDF guide
http://www.tp-link.us/resources/document/TL-WR941ND_V5_QIG_7106504193.pdf
WORKED LIKE A CHARM
the s4 just has new wifi technology that old routers are not compatible with, so at least thats what samsung said when i called them @roni2915
so first of all i own a galaxy s (very first one) used to own a galaxy s3 and now a galaxy s4 and everyone works fine with my router BUT the reason I am posting here is, that both of my wifes iphones (3gs and 5) had problems with my router and I was able to fix it by using a different encryption method. I used to have my router on WPA/WPA2 and changed it to WPA2 only and now i am having no compatibility issues plus i didnt have to downgrade my encryption security.
oh and regarding this new "wifi technology" which the s4 happens to use, my router is 2 years old and with the above settings it connects just fine
maybe you find my post helpfull
Just unplug your router for 10 seconds and then plug it back. Try again to connect to your router. Maybe your router doesn't see you new device.

My s3 and my sister's sony xperia acro s and other wifi devices works fine on our previous router. Only the S4 isn't. It always gets stuck on obtaining ip address then fails to obtain one saying the network is too slow and thus got disabled. When we changed our router to a new one it connected instantaneously so i'm pretty certain that this is a router incompatibility issue.
We're using this one btw http://www.tp-link.us/products/details/?categoryid=219&model=TD-W8980 took a week to arrive from the US shipping from our relatives there

Classic router issue, every new generation of phone will have some issue with older access points, in most cases a firmware update to the router / ap can solve the issue, though it does depend how old the AP is and the manufacturer. some Public hotspots are very very very old!

This can work but its rare in my experience, though sometimes factory resetting the AP can help if you have configured it for high band 54GX2 or what ever its called (double speed N) which wasnt standardised to begin with and thus has some issue with devices who are working on the standard. Dropping back to N or G can solve the issue.. just depends on router and setup.

[Q] Unable to join Ad-hoc network

Hi,
I've do some explanation of what i want to do first.
I've an Wifi OBD2 adaptor in my car that allow me to use apps in my Galaxy S4 like Dashcommand. In the past, i'Ve an iPhone, which i can use whit that. But now, my galaxy S4, and many other android device i've try like Galaxy Nexus, or Galaxy S3, doesn't see the adapter wifi network.
I've do some search on the internet, and found it's because Android doesn't support natively the AD-Hoc network mode. Whit the search result, i've found some WPA_Supplicant file that i've put on my rooted phone, and nothing i'Ve try let me use wifi.
I've use the original roms, try in the past Cyanogen Nightlies on a SGS3.
Anyone have an WPA_Supplicant file that compatible whit the S4?
Thank you very much for your help!
