[Q] Wifi signal high but no internet connection (Samsung Galaxy i5500)

I just upgraded my router to a wireless one. Firstly, it's connected via ethernet to a PC and it is happily getting internet access.
On my i5500 I get a strong wifi signal. Wifi Analyser shows the signal at max constantly. I can also connect with Gmote and it works just fine.
The problem is that I can't actually access the net at all from the phone.
So basically I know that my phone is talking to the router with no problem. It's just getting out onto the internet.
Does anyone know of a solution?

try logging into your router and change the broadcast channel to something else and test it again. it should be something like a/b/g mode... define a single channel and see if it works.

I had originally thought that was working. It did for the first few minute where I had connection but then it just dropped.
I have noticed that I have some very small bursts where I can connect.
Do you think that trying the different channels may be the solution?

I have the same problem. Have you found a solution?

Still no solution. I went through every channel and every encryption method.
So far I've found that having the channel set on 'Auto' and then disabling encryption seems to give me internet connection through WIFI for at least the initial period but it eventually drops. But that's also not always.
I've also Googled it to death and found nothing. If you do find the solution please post it here and I'll do the same.
Maybe we can help each other.

make sure you entered the right password of wlan.
use a pc to connect the router and in the wlan you'll find the password.

Ok, just to clarify. My phone connects to the Router via WLAN. In fact I can use Gmote to control my PC. So the WLAN connection is great.
The problem is accessing the internet when using that connection.

I had similar problems with a router last year. I resolved the issues by flashing DD-WRT firmware. The manufacturer's firmware was junk.

I had that idea but they don't have firmware for my router yet. I have asked them if they intend to make one.

Any chance the firewall on your phone is blocking your browser from using the Wifi?

I have no firewall on my phone.

Ok I've tried some new stuff and they I've had the longest connectivity so far (which is about half an hour).
First I made sure my Wifi wasn't set to turn off when the screen goes to sleep. Second, according to a forum I read, Netgear recommends channel 7. If that channels doesn't work try 1,3,6,9,11,13.
I then disabled encryption.
Fortunately no one near me uses Wifi at all and I've got the kind of walls that stop the signal from getting outside.
Anyway. It's working so far but I'll monitor and report.
[edit] And I forgot. The router was checking for firmware but it wasn't actually finding so I downloaded it myself. Seems that also made a difference.

Ok. I can confirm after 2 and a half hours my internet connection is stable. I even left half way through and when I came back it connected perfectly.
So as a summary here's what I did:
1) Get latest firmware
2) Change channel to 7
3) Disable encryption
I will change encryption and see if it still works

[Q] Wireless distance issues with Sharp IS03

I originally posted this in the IS03 sub-thread but received no replies.
Not root-related but since a little under a week ago, my IS03 has been having a real hard trouble with wifi when at home. If I move more than 4 meters or so away form the router, I cannot access anything.
When this happens, I'll disable/renable wifi (from 4-5 meters away or further) and one of two things will happen: 1. My network will not even show up or 2. My network will show up (with a 'good' or 'fair' wifi status) but when I try to connect, it will disconnect immediately.
What I noticed through the Wifi Analyzer app was that even when the Android wouldn't show my network on the network list, wifi analyzer still registered it about -70dbm.
I originally thought the router is to blame but both my wife's AU HTC Evo and my Amazon Kindle have no problems using wifi from the same distance.
I also thought that perhaps the cover I have for the phone may be collecting dust so I removed it to no avail.
Any ideas why the wifi in my phone is acting up?
Thanks.
UPDATE since original post: I moved my router (Linksys WRT160N V3) to a more central location and installed DD-WRT (TX Power power set to default 71) and the problem went away for about a week but now it has returned. Both my Kindle and my wife's Evo have no issues with accessing the internet through wifi from the other side of the apartment but the IS03 cannot.
If I try to connect to wifi and I am right next to the router, one of three things will happen: 1. It WILL connect but I cannot access the net. 2. The network will show up on the available network list but it won't automatically connect (will say the network is disabled. If I try to manually connect, it will immediately disconnect. 3. Network won't even show up.

[Q] Wi-Fi connection problems

I'm having a strange problem lately with the Wi-Fi. I was at work where I've previously set up the wi-fi details, but now it says the network is not in range. The laptop I have sees and connects to it just fine so the connection details haven't changed, and the signal strength is 5 bars on the laptop, so it's still in range.
Well failing that, I connected the laptop to a wired connection and created an Ad-Hoc network to share the internet from. The latest honeycomb 3.2 update added support for Ad-Hoc and the network was seen on the tablet, I typed in the password, but it won't connect. It sees it as full strength, attempts to connect, and then the network suddenly loses all strength gives me a "-1 mbps" link speed and seems to get stuck in an infinite loop of trying to connect.
This same issue happened at a friends place where she has your typical household wi-fi but I thought it was just a fluke. I still get the "-1 mbps" link speed and lack of connectivity. The strange thing is it still works at home and at another friends place.
Does anyone have any experience with this?

yeah i had the same problem. i got Linksys router on WPA\WPA2 personal. But at the same time i changed ISP...150mb/s down and up bebeh! ...so i used the router they gave me instead.
not sure linksys and/or the WPA/WPA2 personal is the problem. But i dont have the problem anymore.

Yeah, it's weird. For the Ad-Hoc connection I was able to change the security type to basic WEP and it worked fine after that. Previous it was WPA2 and not working.
I'm wondering if the latest firmware update has anything to do with this?

[Q] Nexus one, hotspot intermittent connection problems

The connection is not dropped anywhere: 3G stays connected on the phone and the wifi signal is strong groing from the nexus/hotspot to the laptop connected to it and is not dropped.
But after a while, the laptop starts to get no data at all from the phone (as in, it requests data but nothing comes back). The laptop is fine as it works with no problems using my home's router via wireless.
I can usually ping the nexus fine when this problem occurs, but pings to the outside do not go through, as you'd expect.
I end up having to restart the hotspot function (a phone reboot fixes it too). Does anyone know what might be the problem? Or how I could troubleshoot it?
The nexus one is running CM 7.0.3. Google did not reveal any results (or I failed to find the correct keywords)...

Wifi Connection Issues since Oreo

Is anyone else experiencing connection difficulties with wifi since Oreo? Both at work & home with good, strong wifi signals my phone struggles holding onto wifi. Continually drops & struggles to reconnect like I'm on the edge of a signal (but I'm not, mere feet from a router). THen once connected it'll sit with an x through the icon.
Never had this before the update. On bone stock, locked Oreo OPR6.170623.011. Already tried resetting network settings to no avail.
Edit: Been running in safe mode for awhile and it seems to have alleviated the issue. So now it's time to figure out what app isn't playing nice.

I had that. Turned off such to mobile data automatically

I had the exact same issue. I factory reset my phone twice and did not restore any apps and had the same problem. Phone was under warranty so received a replacement which I am keeping on 7.1.2 for now. No issues yet.

I have a Unifi AP lite setup. Maybe I never noticed it before, but I was using a Rasberry Pi as my manager, but now I'm using an actual cloud key.
I've tried messing with all manner of settings and channels and band steering and AP names with no luck. My Pixel XL 8.0.0 will connect stay on for a bit and drop then reconnect. It never misses a beat, to be honest, I don't notice drops in connection. I am also noticing it in my Nexus 7 2013. My laptop seems stable, my girlfriend hasn't said anything about her iPhone or laptop. My Xbox one is stable, as is my switch.
I've reset network settings and tried the safe mode thing with no luck. I may do a factory reset this weekend if I can find the time.
In the mean time, I'm happy to have unlimited data at the moment.

I think I've narrowed it down to using a custom DNS. I was using a RasPi with Pi-Hole and my phone could not stay connected to wifi. I turned off the router pointing to my pi and boom, strong signal.
I tried manually assigning my IP / DNS etc in android 8.0.0 and it would not connect or hold a connection. I tried to connect it to 8.8.8.8 with no luck either. Back to stock DHCP assigned and I have a strong stable connection.

same issue not too sure what to do...is there a way to downgrade wifi driver?

Same here, time capsule as router and DNS set to pi hole, pixel drops wifi connection - any way to resolve this? I don't want to switch off pi hole

So I have a stupid network, I'll try to upload a diagram of it here. My apartment internet only comes in in the kitchen and cannot go anywhere else unless I get a different provider, even then I'm not sure.
I moved the Pi to the router/switch that connects to the AP instead of on the other side of my network bridge and I have had 0 problems since. The attached diagram is my old setup as I was trying to explain it to people. Sorry it's not very pro.
