Maybe your router only supports a limited number of devices and your phone is pushing it over that limit. Also, you could try switching the Wi-Fi frequency band in the Advanced Wi-Fi settings from "Auto" to whichever frequency your Wi-Fi operates on.

Have you rebooted your router by pulling the power cable and then putting it back in place again.
A router will often refuse an Internet connection from a mobile device that regularly disconnects and re-connects all the time. This is normal and happens to laptops for mobile users all the time.

[Q] Tab won't find my wi-fi

I seem to be having some problems with my tab gray 16 gb wifi version.
When i started it for the first time it could not find my wifi, i went ahead with setup and when i was finished i looked into wifi settings and it had found my router.
A few days went by and all of a sudden i was connected to the router but had no internet connection, I checked my computer which was connected by wire and it had internet connection. I then tried to switch wifi on and off on the tab and since then i cannot find my router.
I've tried rebooting both router and tab and it has not resolved the problem. Anyone else experiencing these issues? Any solutions? I thank you all in advance.
btw the router is a D-link dir-655

Unplug the router and plug it back in. I have experience this issue as well. My desktop was able to connect to the Internet. But my laptop won't connect through wireless. Not even my wireless printer. I unplugged it and plugged it back in, and it works fine. Sometimes, it's other way round.

I have the same router and I don't have any problems connecting. I did have many problems with my OG Droid phone connecting though, until I switched from WEP to WPA encryption.
Can you see the router on your Tab, but it just won't connect? Or is it not visible at all?
I have tried unplugging the router leaving it unplugged for 30 sexonds or so and then plugging it back in, no luck. And no I cant even see the router, I see lots of routers but not mine, I can connect to my phone using mobile access point but just not my router
Does your router use a hidden SSID?

This might sound funny, but do you have anything else connected to the WiFi? My router sometimes does this same exact thing and it happens to do with the traffic going through it. It happens alot when I'm using my laptop and my Xbox 360 and I turn off my Xbox for some reason. The way that I've always found that fixes it, is by rebooting all my connected devices along with rebooting my router. It's as if their is a conflict with the connections that make it not work.
No hidden SSID and at the moment nothing is connected to my router wireless
edit: Solution! logged in to my router switch of wi-fi, turned it back on, enabled wpa2 security and there it was right on my tab, welcome back old friend
I had the same problem, but solved it by changing locale setting on my router from Czech Republic (where I live) to USA.
figure out how many devices are connected to your router. My router can hold only five devices at a time. Also change the channel in your router settings.
good to know problem is solved

[Q] strange wifi problem

I am on bionix 1.3.1 and have noticed that whenever I turn my wifi on it seems to not allow me data access. My web browser will not connect to a page, market won't load, and any downloads that were in progress will fail. it's as if turning on the wifi is overriding my data connection and blocking it. It says that it's connected in the menu though. Any advice?
Thanks
Edit: I just noticed when looking at my phone stats, that when I turn on my wifi my mobile network state says disconnected, and it connects again when wifi is turned off.
Also, I have an airport extreme and a mac, perhaps that is my problem. I've scoured the internet and found a bunch of info about this problem, but haven't found anything that works yet.

Im sure someone will correct me if Im wrong but if you switch from wifi to 3g while downloading the download usually will fail because you were using only wifi to download the content and when that turned off it doesn't just switch to using 3g you have to manually retry the download using 3g .... when wifi and 3g are on wifi doesn't speed up the 3g instead it does the internet related work and the 3g does the text and phone call related work
that makes sense, thanks. as for the connection problem, it is definitely mac related. my wifi seems to work on other networks. I just need to figure out how to make it work with the airport. It's just weird to me that it says it's connected and shows signal bars, but won't access the internet.

so is the new problem that the airport extreme won't give wifi to your phone or that its not working at all
According to my phone I am connected via wifi to my network from the airport, however, the phone cannot access any internet functions when connected. When I disable wifi, it works fine with 3g or edge. It seems to be something with the settings on my airport, not the phone itself.

Help with this very frustrating wifi problem on my Tablet S!

Hi,
I got a new Sony Tablet S a few weeks back and I have this really weird problem.
As soon as I on Wifi and connect to my college network, it connects fine and webpages open as expected.
But after a minute or so, all data transfer stops even though I am connected to the network. Initially I thought
it was a hardware issue with my tablet but when I went to my nearest McDonalds and connected to their connection, everything
worked fine and there was no interruption in the data transfer.
I tried a couple of other hotspots around town and they seemed to work fine.
So, now obviously its a problem with my college network. The funny thing is that my laptop, my cellphone and about a thousand other devices
connected to the same network work just fine and do not stop exchanging data all of a sudden.
I have tried various apps available on the Play store but none helped.
My (geeky) friend told me that the issue may be some sort of interference between the routers (Cisco Aironet series, I think), as every floor in my hostel has 4 routers, but he could not give a solution. I have also referred the problem to my system administrator but he too could not come up with a solution.
If anyone has a solution to this, please help!
Thanks in advance
Really strange.
I have a rule that occasionally works, strange probelms can be sorted out by a restart, if not, a reset mostly helps.
Can I suggest resetting your tab if not done yet!

Did both. Doesn't help.
you need to re-flash the wifi modules, which comes with the kernel usually. But I dont think that possible at the moment.
Can you elaborate?
I have the same problem with my tablet, and when I called Sony for technical support, they said that the tablet is not compatible with the router I have. Which in my honest opinion dont think is the problem.
But as a way around, what I do is turn off the wifi for few seconds and then turn it back on.
This way the problem gets resolved.
I hope it helps you.
I have exactly the same problem, unfortunately the problem is with the wifi in my home, my sony tablet connect and disconnects, or it stop transmitting after a while, but other devices (my htc phone, my tablet, ipad, iphone) doesn't have this problem.
and as you said, when I go to other places the tablet works fine.
Someone said me that the tablet is not compatible with the motorola router of my ISP
I've been searching but there is no solution, by now I turn off and turn on the wifi every time I lost internet
Thanks people, but this is hardly a solution. It means I need to turn on and turn off the wifi every 60 seconds to browse the internet. Bye bye downloads, buffering videos and installing apps through the play store
Is the Sony Tablet S the only tablet in the world that is incompatible with routers? Then Sony should make sure that its clearly listed on their website that routers from major companies are not compatible with our Tablet
I solved the problem .. at last for me,
1 - turn off wifi.
2- in accounts - turn off "auto connect"
3- turn on wifi ( test if work )
4- reconect the accounts
too simple .. but works , try it..
I am sorry but its not working (that is if by auto connect, you meant auto sync)
Are you sure you are telling the solution to the problem I mentioned or something else?
Hi, I was suffering exactly the same problem and it boiled down that was a compatibility issue with the router. Unfortunately I could not find any other solution but replace the router itself!

Looks like I have to do the same. except I cant make my institute change their routers
What kind of encryption are you using on your router? Try disabling the encryption and see if the problem persists.
Also, what channel are you broadcasting on? It could be a highly populated channel, try changing that if you can.
I don't know what options are available through your routers configuration page.
I will enqure with my system admin and get back.
Meanwhile, I got a workaround to this problem. There is a freeware called MyPublicWifi which creates a virtual hotspot on my computer. This hotspot works fine and I can share my router's internet through this, even though it means I need to keep my PC on while browsing on my tablet.
I have experienced exactly the same problem since I bought the tablet. The router I have at home is a Buffalo WZR-HP-G300NH2. After a very long time trial-and-error, I have found a solution to it.
(1) Router setting: Force to set the 300Mbps mode of Buffalo router to 20MHz, not auto nor 40MHz. Some routers may display 150Mbps mode.
(2) Tablet setting: Settings->Wifi->advanced->Wi-fi disconnect policy, set to "Never"
You may try it and I think this will resolve the wifi disconnection problem. As for the reason, I think it is related to 11n because I have not found any problem with 11a/b/g router yet.
Hope this helps!!

Can I hook up my Vibrant to a router?

I'm not talking about using my phones wifi to connect my phone to my home network. I got my internet shut off for a couple of days and want to use my phone as my internet for my house until I get cable back on. I know I could turn on the wifi tethering and have my devices use that but what I am trying to do is different. I have one of my roku players disengaged from my home network (an accident) and it will not reconnect to it (so I can stream my files from my PC) because when it goes through the testing on the roku it cannot access the internet on the home network, so it won't connect to my home network. My theory is that if I can connect my phone to my router, my roku will be able to connect to my home network because it will now have internet connectivity. I just don't know how to do it if its even possible.
I hope that makes sense.
I have a dlink dir-632 wireless n router, if it helps.
My friend u can use Commview for Wifi is google it and i think it will work for you. If u have any doubt pm me

WiFi LAN with no internet connection unstable

Hi,
I have a wireless router that allows me to plug in a Hard drive / SD Card etc. It can be a bridge to another network or an Access Point etc but can also just be a LAN without an internet connection allowing access to the connected devices.
This works perfectly on my Nexus tablet / PC etc, however, on my Mate 20 Pro, the connection is unstable to the point of not being able to use it. I get a notification saying the WiFi connection doesn't have an internet connection I press connect anyway and from there it keeps dropping and reconnecting the connection.
If I plug the router into a network point and give it an internet connection it works perfectly on the Mate 20 and any other devices.
I think this is some clever connection manager thing Huawei is doing to try to connect to the internet but can't find a way to stop it. I am going travelling and wanted to only take the router and my phone however it is looking like I will need to take my tablet too to use it for what I need.
I've searched and searched the internet and here for clues but nothing so I am hoping someone has an idea.
Thanks
Andrew
