I've been having problems with web browsing on wifi. I can go to certain web pages such as google and i can search stuff but when i try to go to other web pages either they half load or it says network connection error.
I know my router was having DNS issues because all the computers i had to set the DNS to google DNS for it to work. I set my phone's DNS to google but it didn't seem to work. Also i've tried many different browsers all to the same result. I also went from stock rom to android hd revolution, same problems. It is getting pretty annoying, i feel like it is a DNS issue but i changed it to googles 8.8.8.8.. sooo

Just got my Samsung Captivate about a month and I got my wifi connected to the school network, but when i open the broswer or any apps need internet i didnt get any connections? at the first week it works.. and when connecting to the school wifi it should be come out with the school login page,, then the internet will work.. however the wifi is connected doesnt matter how strong the wifi singal is.. it just cant load and cant bring me to the login page..
I really need help..
and the wifi works everywhere.. except my school...
btw my friends iphone 3gs works..
I am also at college and have had the same problem. the best reason I have found is the phone itself. half of our wifi is an older standard that does not work on the phone. it shows up as wep and i can not get it to recognize it as 802.1x . in my tinkering I have also messed up the wifi that was working.
long story short it probably won't work. I have spent a long time trying to get it to work with no luck

Hello to both of you,
I also attend a college with an 802.1x connection and the captivate supports most of these networks; however you will probably need to configure the network settings manually (usually retrievable on your schools IT site). If you dont mind digging up your settings I would love to check to see if I can configure your phone.
FYI, you might be having a problem similar to what's seen in this post.

I definitely had this problem today. It appeared connected but no web pages would load. Going to have to investigate further. Why can't things just work
I know my school recently implemented some new security certificates that you must agree to before logging in, has anything like that changed for you? My wife's Aria is running 2.2 and can log into the school network, but my captivate cannot. It is frustrating I know.
Seems some colleges and universities are noticing issues with android devices letting the DHCP leases to expire but keeps using the IP address assigned instead of requesting a new one.
See the following links.

I actually have similar issues with my Belkin wireless router at home. My laptops and other wireless devices have no problems connecting or re-connecting but the Captivate just refuses to re-connect after the connection was terminated. Even after resetting the router, the phone just keeps trying to use the same IP address for some reason.
The only way I could get it to reconnect is to either reboot the phone or to remove the AP entry which is a pain especially if you have wireless passwords.
Hopefully someone with better insight into how Eclair and Froyo handles WiFi can come up with some fix.
more solutions?
I believe the new 2.2 firmware solves this issue. I too am at College and my captivate FAILS to actually access the internet through wifi unless I statically assigned the IP.
I just updated to Froyo and it connected instantly. I'll have to do more testing to make sure, but I think Samsung finally fixed it.
captivate wifi issue at school
i just got Galaxy S (Captivate) and wi-fi is giving trouble.
when i tried at a university campus, it gives error and says can't open and try again later. it is like, i get connected to the network, IP and DNS and everything is generated. But when i open browser to open a website, instead of taking me to login page it gives the above error.
here is what i get when i try to open a website.
'web page not available'. the page might be temporarily down or it may have been moved permanently to new address.
here are some suggestions:
- check to make sure device has signal and data connection. (I made sure it is connected to wifi)
- reload page later. (i tried after 5 mins, same result)
- view cached copy from google. (doesn't work either)
i am not able to understand why is this happening. i tried restarting the phone after connecting to wifi but no luck. any pointers?
Sounds like they use a portal system which requires logon and doesn't play nice with the Captivate's browser. Unfortunately many such portal systems are written poorly and I've even seen some that only work with Internet Explorer.
You could try a different browser on the Captivate. Dolphin allows spoofing assorted User Agents, which might help.
Hey guys, I have the same problem connecting to m school's network login page. It would say connected but the website always says cant be found. But the good news is that I found a way to connect to it manually! What you need is your captivate and friends iphone 4 or 3gs. First have use your friends iphone to connect to the wifi and then go into wifi settings. You should see 2 DNS address, Ip address, netmask (subnet mask) and router address. Now jot those addresses down except the ip address. Go to settings->wireless and network->Wi-Fi settings->now tap the bottom left button under the samsung logo and click advanced. Now check use static ip. Do not enter anything for your ip address just yet (we will do this last). Now enter router address into gateway, subnet mask into netmask, DNS1 to DNS1 and DNS2 to DNS2. ok when you are done click back and tap the network you want to connect to. Once you are connected jot down your ip address by taping the network once more. now go back to where the static ip was and input the ip address you just jot down into the ip address underneath use static ip. Disconnect and reconnect to the desired network. You may have to do this a few times or reboot your phone. This has been working for me so far around different buildings but with the same school network connection. I hope this helps cheers!

Yeah, my school uses the Bradford dissovable agent. Funny thing is, some connections work perfectly, others not at all. Technically none should work, and sometimes I feel that maybe I should tell them that sometimes somehow it is possible to bypass the whole agent thing- but why rock the boat just yet
Does it need a proxy to work? If so, this app is amazing.

I figured it out a month ago, and it is actually petty easy. But you really have to change ip address manually, usually just the last number.

I've searched, and all I found was the trick to *#*#4636#*#* then cypher off, radio off, radio on, cypher on
... which doesn't work.
Here's my issue: The market works.
I mean, it only works on Wifi. If I turn off wifi, or head to a location without wifi, and I try to access the market it gives a data connection error - same with other apps. I have no idea why, but only certain ones are affected.
For example, on 3G/4G, I can get onto the Internet using the standard web browser, or browse, google+, facebook, twitter, etc, all just fine, quick as ever. but try to open the Market and it times out waiting for a response? try again on Wifi, and it takes no time at all to pop up.
Here's where it gets really weird. I've noticed that HTTPS causes a lot of slowdowns on my APN, I noticed it with my previous cellphones, going to HTTPS sites, and it's an order of magnitude slower, which, if the Market (and others) are using SSL, could cause the issue, especially if their timeout is shorter than the browser - but the weird thing is, Twitter is setup to use HTTPS always, and it does not seem to take very long to get updates from the server when refreshing my feed.
I'm confused. I just want the Market to work whenever I need it to.
Any ideas?
I use iGoogle for my homepage in all the browsers on my phone. My iGoogle has about 10 website feed gadgets. Recently, all of these (except the Verge) started displaying Feed is Unavailable. If I use wifi, I get the feeds, so I figured it had something to do with AT&T DNS servers.
I got Set DNS from the market and set the dns for google servers. Then had to close the browser, go into Airplane mode and back out, bring the browser back up, then I get the igoogle feeds again.
I have to do this every time I restart my phone or it changes data sources (4g to 3g, for example), which is a pain. Is there any way to set the DNS servers without an app so it sticks through a reboot or change of data source? I am running Sky ICS.
Anyone having this issue. Not exactly sure what changed in my wifi setup but in the facebook and instagram apps photos in my feed wont load. When i switch over to mobile data or use the web page in the browser over wifi they load fine. For some reason my wifi does not play nice with instagram and facebook apps. This is on my galaxy s4 but have tried several different devices and they all have the same issue.
Has anyone run into this problem? Tried searched and found some people who had the opposite issue with it not loading over mobile data but havent found a thread on this. Thanks for any tips.
I am having the exact same issues. Any help would be greatly appreciated.

I'm a facebook beta tester, Facebook fixed the issue in the latest version. That means you guys will have it between now and next week.

I am having the exact same issue, its seem to be a router problem, my newsfeed load fine one 4g and other wifi (i have a galaxy s2), but on my home wifi the newsfeed for facebook or instagram won't load, my sister is also experiencing the same problem with here galaxy S......any suggestions would be greatly appreciated.
FYI: i've tried restarting the router, upgrading the firmware which didn't work. also before i realized it was just the router i've tried force closing, clearing the cache and restarting the phone, i've also uninstall and reinstall the app several times.
I had a similar problem but I sorted it out today on my Nexus 4. My problem was, the default gateway on my phone was different from what it has to be for that specific wifi network.
In windows one can check the default gateway by running command prompt (cmd) and typing ipconfig.
On your phone you also have to check the advanced settings for that wifi network that you have problems with.
I set the Ip settings to static from DHCP and entered the default gateway values from my pc to my phone. You can also get another ip for your phone in that advanced settings tab if you think there may be an ip conflict but as I told, my problem was the differing default gateway values. I haven't changed the DNS which was google dns by default.
Key thing was the default gateway values for me and I'm hoping this will help many of you.
Problem Fix
if ur Instagram installed on ur sdCard then just move it to ur mobile memory it's 101% working
Here's what's happening, only since I've been trying to flash a custom ROM....never had this problem with this site before.
When connected to hostpot:
I go to a certain website, and it just saying "waiting for www....." it doesn't matter what browser I use.
When connected to other wifi hotposts like optimumwifi:
I go to the same website and it loads without any issues.
When I use my phones browser:
I go to the same website and it loads without any issues.
Someone please help, this is super annoying. Also, I should note that 99.999% of website are loading without issue.
My best guess is that HotSpot maybr blocking some sites, ut happens. I always use custom forced dns address. I prefer opendns
208.67.222.222 second can be blank or use Google 8.8.8.8.
There are free dns apps, or you can set advanced ip (static) under that wifi, but note that HotSpot ip usually changes.
