Hi guys,
I've recently become the proud owner of a vodafone touch pro. However when connecting to wifi, opera etc will not find any webpages. Now i know my wifi is working and the phone connects fine and picks up the DHCP ip address.
What could I be doing wrong? I've noticed data connections is disabled but I believe this is just for GPRS etc? Either way how can I confirm my wifi connection is being used?
Many thanks
EDIT - NM it was because it was not set to work
Hi Scribe,
I had the same problem as yours. No solution so far. Had no problem with GPRS.
I have mine working good on either wifi or GPRS.
Probably it's wifi problem? Have you tried on another wifi connection?
what was not set to work?
I have the same issue, connects to wifi but no internet. laptop connects and browses fine, but touch pro (and also diamond) don't
Make sure when you set your wifi connection up you say that it is used to connect to work not the internet, also make sure your adapter settings say this.
The problem is that the phone will always default to GPRS/3G for the internet but if it senses a local work network it will use that first.
Stupid I know!
I have the same prob, I changed some settings and it works. Try change Authentication to Shared instead of WAP-PSK, Data Encryption to WEP instead of TKIP. After you have internet connection, you can change to previous wifi settings with same network key.
Mine has gone again! I swear it's because 'Connects to the internet' wont save in the proxy settings - nope not that and still wont work, I've also tried by disabling all security
Has anyone had a problem with the Captivate when in both WIFI and 3G coverage the phone will not download or open a webpage? If I shut off one or the other it works but if both are active it hangs up and doesnt download.
Is this by chance on an enterprise wifi access point? Such as one of those expensive cisco APs you find in schools and enterprise class networks? If so, there is currently a driver problem with the captivate connecting to it, but not trasnfering data. Whether the netwrok is encrypted or open doesnt seems to matter. Personally, I find this a bigger problem than the GPS issue. I had to use wifi static to manually set IP, subnet, etc. This is a workaround, not a fix.

Hey, I think I'm running into this issue at my workplace (we definitely use those Cisco APs, I see them all around). I'm connected, I have an IP, but I can't browse anywhere.
Here's the weird thing though: I can connect to the company's wifi in any other building (I guess different APs?) than the one I'm in and wifi works fine. It's just the building my cubicle's in that doesn't work and it's infuriating!
well thats dumb.
I had that happen once since I bought the phone on launch. I restarted my phone and it went away.
I've had this problem as well, usually my phone switches to only wifi pretty quickly though, so I don't notice much. The phone acts like it is using the 3G connection because the arrows are both indicating data coming and going, but nothing actually happens unless only one or the other is on.
i need to check this at more places but at home i have a standard dlink dl-624 router with no security over comcast. i think my issue initially was because of the wifi sleep policy (see below) but now i am just getting really really slow speeds. pages seem to load slower than 3G....(i mean really cinemaxHD is showing last of the mohicans in pan and scan)....also the pages time out very very frequently.....
Anyone having problems check out the advanced setting for wifi. The phone has a WIFI sleep policy. my default setting was to disconnect from wifi after the screen locks. my screen locks after 30 seconds. so basically it always looking for my network. you can change it to never.
I want to reiterate our findings again. There are multiple threads on other forums concerning this as well. When it comes to wifi, the captivate has a major problem. DHCP does not work on enterprise networks. Period. It is a driver issue. The network can be open or using any form of encryption, the results are thr same. I had numerous software, hardware and network analyst tackling this issue all week in my department. It is related in part to most enterprise networks not using a default subnet mask of 255.255.255.0. There is a workaround, but it is not a fix. You can either set a static from your static pool of ip's in wifi settings, or, if u connect to multiple networks, use wifi static from the market to remember and apply seperate static configs accross multiple networks which is what were having to do currently. This affects all captivates, one which we consider a major problem with deploying this phone to our other users.

I had the same problem and this is how a turn around the problem when I'm connected but cannot browse.
-Use Wifi Static
- DNS from google 8.8.8.8,8.8.4.4
- switch to airplane mode
- activate wifi
- test my conection (open the browser and surf)
- switch to phone mode
Hope it help

Did this, Wifi Static was being used previously to bypass dhcp, and it correctly assigned the IP settings, used the static I assigned from our static pool of addresses. Still no data transfer over Cisco APs at work.

are you able to access a website thru his IP address? in this case it's a DNS problem, try the Google DNS 8.8.8.8 - 8.8.4.4

Its hit or miss really, seems the wifi radio stack locks up and stops responding according to our trace logs. yes i have tried both our internal DNS server's as well as googles. Everywhere else works perfectly. But at work with our Cisco open (no security) APs, it doesnt work most of the time. Through whos ip address??? I have a static set from our static pool to make sure dhcp was not the culprit. Its def the device, and not my netwrok. I have over 100 of these APs deployed here.
Wifi works great everywhere else (at home with WPA2, etc). There is def a problem with enterprise cisco APs.
Netmask issue and cisco AP's
Posted this over in development thread.

Make sure your netmask is correct.
Thanks jhannaman82
I just wanted to give a big thanks to jhannaman82 for posting his company's findings with these wifi issues. My wifi works 100% at home on my linksys tomato router (of course, with a netmask 255.255.255.0). But on my college campus they use an enterprise router setup with 255.255.0.0 and I have been going NUTS trying to figure out if it is my captivate or the network.
I can sometimes get a few minutes of working connection, but it always seems to crap out within 1 or 2 minutes.
I will attempt to fiddle around with switching the dhcp to static IP, and will post my results. Thanks!
edit: no luck with static IP fiddling so far. from my laptop (connected wirelessly), I gathered that the netmask is actually 255.255.248.0... when I set my captivate's netmask to anything other than 255.255.0.0, it does not connect. It says "connected" when I set the netmask to 255.255.0.0, but as usual no data will transfer (it seems). I'm at a loss. *shrug* Hopefully there's a driver update or something.
Thanks jhannaman82!
I just wrote a script with the GScript app: "ifconfig eth0 netmask 255.255.255.0", and have a shortcut on homescreen. The problem was that the netmask was wrongly set to 255.255.0.0 on my office wifi. Now all I need to do is tap on this shortcut at office, and the connection works!
Has anyone contacted Samsung about this ?
I'm hoping this gets fixed soon... This refuses to stay connected at my school. Huge pain.
I entered in an IP address and 255.255.252.0 for my netmask after seeing what it was on my computer and turn on flight mode and tested the wifi and now it's working. I'm not sure if it's just one of those fluke connections that I get... but we'll see.
Has anyone been able to get a VPN (PPTP, L2TP, or OpenVPN) to work while connected Verizon 3G or LTE? I have a work VPN and Private Internet Access and both exhibit the same issues. They will connect, work for a bit of data transfer, and then drop. The drops are caused by the mobile data connection resetting (icon will be grayed out before becoming solid white again). VPN works completely fine on Wifi though.

I have been trying to get the this ironed out as well. Have you tried the client "OpenVPN for Android"? and I'm using a TCP port instead of UDP. My other thought has been it seems like the connection resets more often while I'm mobile. I my location doesn't change I have greater up time.

I have tried that one and the OpenVPN stock app, VPNRoot, and the stock android client. All have the same problem. I don't get drops ever on WiFi, only on mobile.
I have also tried some other things like mssfix and setting a lower MTU, but neither have worked so far.
Currently running Sow Nice OJC on my G920T. I've been running into some odd WiFi issues...namely with DNS and addressing. At my and my girlfriend's house, WiFi is pretty much pointless as I get DNS errors. Her connection is using the standard Xfinity all-in-one modem/router which isn't configurable worth a damn...but her phone and tablet work fine via WiFi, as does my laptop. At my house I have my own modem and router; I have the DHCP server set up to use Google's public DNS servers. All my devices in my house work fine...Xbox, computer, even Chromecast...but for whatever reason my S6 runs into DNS errors which of course disables WiFi Calling as well.
I have tried running static IP and manually setting Google DNS as well as other DNS; it doesn't seem to help. I have also tried toggling airplane mode. I haven't experimented much with other connections that aren't Comcast, so I will include that in my troubleshooting. I am unsure if this is related to the issue I was having with connecting to my GoPro via WiFi.
Anyone else out there running Lollipop have DNS issues (or don't) and have found a solution? It isn't a huge issue at the moment as I have good signal at both places, but I would like to be able to use WiFi for the bandwidth...
Still working on this...it appears to be an IPv4 issue. All devices in my house happily get an ipv4 address alongside ipv6. Not the S6....it only uses ipv6.
Short version:
When I turn on my phone's hotspot I want to control the IP addresses it uses. It wants itself to be 192.168.43.135 most of the time, and I need to set it to something else more or less permanently. The address it wants to use is causing conflicts. Can you please help me figure out how to do this?
Long version:
My wife and I use our phones as our home's internet source. Till now, we've just been connecting things directly to our own hotspots individually as needed. However, we now have many more devices wanting a stable connection, so I bought several routers (Asus RT-AX92U). I've set two up as bridges, one connects to my hotspot, and the other to my wife's hotspot. These bridges feed into the third router set up as dual-wan, to either aggregate or fail-over. All this seems to work, EXCEPT, both phone's seem to want to dhcp the IP addresses used over their hotspot connection. I suspect this is causing IP conflicts when both phones are setting their own IP addresss on the same subnet, and their gateway addresses also exactly the same. I've tried setting static IP addresses in the bridges, but then even though their wifi connection remains, the access to the internet drops. I think I need to tell the phone what subnet to use to correct the problem.
Someone please help!
Thanks in advance.

PS. both our N20u's are bootloader unlocked. So, you know, I can probably control anything that needs to be, if I only knew what and where.
You'd need to root the phone for that - OneUI does not let you finetune the hotspot functionality unfortunately. In fact, Android itself hardcodes the tethering IP and DHCP range. Once rooted, you can use any of the root tether apps, many of which allow setting your own DHCP ranges and IP addresses.
Another, possibly better solution would be if you took a home broadband data line from your provider/carrier, and used a USB 4G dongle with that.

Could you recommend a tethering app with that ability? I am rooted. The tethering apps I've looked at either won't do that, or get bad reviews for not working well.

I can't, unfortunately. To be honest, since Android introduced built-in tethering, the market of tether apps have dropped significantly, especially since rooting hasn't been a mainstream thing for the past ~4 years or so.
Why can't you get a real Internet connection? . Main will be the cable/fiber & failover can be your mobile connection.
