In my house I have set up 2 wiress routers. One of them is the main router assigning dhcp and is on channel 1. The other is acting as an access point and is broadcasting on channel 6. Both are using the same ssid, and all of the security settings are the same. Anyway the network works fine. All devices flip to the strongest channel while roaming throughout the house, except this one. This one is locked on the weaker router (further away). I have tried forgetting the network and re-adding it. Any ideas? Is there a way to force the wifi on this to a specific channel?
I use a free app called Wifi Analyzer. You might install the app and look through the various screens to see what is going on in your network (they are easy to use). This will allow you to confirm the actual signal strength at various points in your home. It is possible that one of your neighbors might be using a channel that is interfering with yours. The app will help you understand what is happening.
thanks for the speedy reply! I actually have that app also and love it. that is basically how I know that it's using the weaker channel. I don't have nieghbors so that is not a problem. the biggest thing going to point me in the direction of something wrong on the Samsung is that I have a couple of thunderbolts, an incredible, and 2 wifi laptops that under testing all switch channels correctly.
So I just took another look at wifi analyzer. One of the sceens asked me to instal wifi connector. After I installed that I was able to connect to the specific channel. So thanks again !

Hi
I've had a search in the forums but haven't seen any other posts re. this but wondered if anyone had any ideas?!
Basically I'm having problems connecting to some networks with my Tab 10.1 (stock, updated OTA to the latest TouchWiz UX last week).
I first had a problem last week when I took the device into work - there's an 802.1x EAP network there but it wouldn't even show up in the network list. My SGS2 connects to it without an issue.
Then when I got home tonight (after happily using it at my parents' house during the day) I found it wouldn't connect to my home WiFi (hidden SSID, WPA2). It had connected to this network fine in the past, but now was just sitting showing it as 'not in range' network. At first I thought it might be a router issue (it used to be a little flaky), but then I saw that my iPod and SGS2 were both connecting and working on it without a hitch.
I couldn't see the network at all in WiFi Analyzer (similarly to at work), although it was showing my neighbours' WiFi networks fine. I tried deleting the saved entry and telling the router to broadcast the SSID but it still wouldn't work.
I then put on my WiFi hotspot on my SGS2 (also a previously remembered connection) and it worked absolutely fine!
Does anyone have any ideas where to go next apart from doing a full reset? (which although not the end of the world would be quite a pain).
Thanks for any suggestions/tips!
OK, bit the bullet and restore my device to factory settings - it STILL can't see my home WiFi, despite my SGS2, laptop and iPod all connecting to it fine. It is however showing up two networks belonging to neighbours and also my SGS2 if I put it in WiFi hotspot mode!
Any suggestions folks??
Sounds like a route issue, did you reboot the router? Is the router on a channel below 12?
Hi thanks for the reply!
I actually just spotted a post at http://www.thegalaxytabforum.com/index.php?/topic/5511-my-wifi-no-longer-works/ with the same issue.
It looks like Samsung have mucked something up when they made the Touchwiz UX update - it now blocks WiFi channels 12 upwards, when the old stock Honeycomb firmware didn't do this. I'd moved my router onto 13 to reduce congestion and I guess the work one must be on 12/13 too.
I can see from the table at http://en.wikipedia.org/wiki/List_of_WLAN_channels that 12/13 are only allowed under low-power conditions in the USA, but this isn't the case elsewhere so they shouldn't have locked it down outside of the USA.
This also happend to me

As I had setup an additional router in my house (with assigned a high numbered -or so i thought- fixed IP address) for some reason my main router tryied unseccesfully to assign the same IP to my SGT as the router. This had obviously conflicts and could not log in.
Went into the router eliminated the fixed IP address and voilá! it got working again, all IP a dinamic!!

I live very close to a hotel which has multiple SSID's that keep interfering with my ability to stay connected to my router.
I've tried hard coding a static ip on the phone, adding the mac address to router, even went as far as creating a separate unhidden network just for the phone. So far, nothing has worked.
So i was thinking that maybe there's a way to have the phone ignore certain signals, lock on to a preferred one or use WiFi but turn off the scanning feature. The only problem is that I haven't been able to find any settings or Apps that will allow me to do it.
So, if anyone has any ideas or suggestions as how, or if, I can make this work, I would greatly appreciate it.
I'm using a Droid 2 Rooted with 2.3.3 and have a Netgear N750 router.
BTW - none of the computers in the house are having this issue.

So, are you saying the phone constantly tries to leave your home wifi in favor of attempting to connect to the hotel's?
Yes, unless I'm within about 5 feet of my router, the hotel's signal makes the phone keep dropping and reconnecting over and over again.

Are the hotel's hotspots not WEP secured? That is so odd. If they're unsecured hotspots go over to the hotel and tell them to get their sh*t in order. Otherwise I'm out of ideas, sorry.
No, they are secure. WPA2 as is mine. I don't connect to them. My phone just detects them, drops my connection and tries to connect to them. So that leaves me with no connection and having to use 3G.
But there may be an easier solution to this. After spending a few hours on the Netgear site, it turns out that there is a bug in their firmware that causes signal strength fluctuations. They said a new release should be available in a few weeks.
In the meantime I've changed the channel on the router to auto select which seems to be helping.
I do appreciate you taking the time to assist.
Thanks!

Glad there's at least some kind of work around, wish I was of more assistance.
Having a similar problem with a samsung galaxy sii - current internet configuration is through AT&T U-Verse with built in Wireless G router in there Gateway. tried adding a Netgear dual band N router to my network and with the netgear's 2 wifi signals on then my phone just constantly goes into scanning mode and keeps trying to connect between the 3 - things work fine with the wifi turned off in the new netgear kind of defeating the purpose of me installing it - was hoping to have the phone use one of the N signals..
Block bt openzone connection pleaseee!
Desperately need an app for this? Is it not going to be possible for a way to block certain wifi signals because I'm actually going to rip next doors BT openzone router out of the wall and get a hammer to it! My HTC desire hd is insistent on connecting to its poor signal over our excellent one and the worst part is that you can't actually access the network unless you pay BT for a user account! Grrrr.... Please help
Try to connect the network you dont want, then go to wifi management in settings. Long press on the network you dont want and hit forget network. Then your phone shouldnt automatically connect to it unless you tell it to.
Hopefully this is another known bug in 4.2 but on my N10 the wifi frequently drops from my router if I connect to a SSID with multiple access points.
Basically I have 3 x 2.4Ghz and 1 x 5Ghz access points around my house. All APs are on the same subnet, have the same network name (SSID) and same security settings. All my other devices (laptops, ipad, android gingerbread, android ICS, etc) all play nice with this and move seamlessly from one AP to the other when moving around the house. My new Nexus 10, on the other hand, does not. Even sitting in one room, right next to one of the APs it will randomly drop and reconnect to the network. Wifi analyser shows that the signal to all APs is fine. I'm guessing its flicking between APs.
As a workaround I changed the SSID on one of the APs to be unique and told it to connect to that - its been fine since but obviously this isnt the ideal solution.
Another 4.2 bug?
I've never had any luck with Android and multiple WAPs with the same SSID. At least for handoffs so I was forced to use mutliple SSIDs. Wish Google would get this taken care of! One of my only real complaints with Android...
I just found and installed this...
https://play.google.com/store/apps/details?id=com.heleron.wifistrongestsignal&hl=en
Not sure if it works yet.
Theres also an open bug:
http://code.google.com/p/android/issues/detail?id=12649
I'll report back...
My Nexus 10 works fine on most WiFi networks, but there are a few places where it fails. The N10 sees the network which has fine signal strength. It goes to the "Connecting" state, waits 30 seconds or so, and then drops back to "Saved".
I would think the network had non-functional DHCP, but I can connect with a Lenovo notebook instantly from the same place to the same network and AP.
The router that causes the problem is a Cisco 1200 series AP, operating vanilla 802.11g, with an open network, in the 2.4 GHz band.
I have tried all the Wi-Fi-related options in the N10, and removed and recreated the connection. I have found nothing that helps.
Has anyone that has seen this issue found a solution?

Seen this a million times, and it's one of my lingering dislikes about Android (although to be fair, I've seen the analogue -- much less -- on my iPad as well). Toggling the Wi-Fi state on and off like mad (or Airplane Mode) usually does the trick for me...eventually. Have you tried rebooting the router (relatively sure you've have, sorry) or using an app like Wi-Fi Analyzer from the Play Store to see if there's any channel interference? Mobile devices don't always deal well with overlapping channel use.

I cannot reboot the router because I have the problem in a public place (an airport). I do not have the problem with my own router.
I do use a WiFi analyzer, and there is no interference issue. The AP is on a clear channel, and the signal is very strong.
So the only and best solution it to turn Wi-Fi on an off rapidly until it works? Really?????

Never said it wasn't stupid. It's possible that the airport is using a network hack to facilitate its captive portal (I assume it uses some kind of gateway?), and Android is really bad about network "misconfigurations."
Is there anyway of using the super hub 1 from virgin media to act as a wifi extender/repeater?
I currently have a super hub 2 connected but in some spots of the house i cant access wifi or its a poor signal so o was tjinking if it is possible to create a wifi extender from the super hub 1? Any help would be appreciated, and thanks.

It is possible, the easest way is to first change some settings on your old hub, you will need to disable built in features such as the DHCP, secondly you may need to change the old hubs ip, if it is the same as the new one, to prevent a ip address conflict (for example, if they are both using 192.168.1.254 though if yours is an old netgear tg834? Then its probably using 192.168.1.1) , now assuming your old super hub supports the same wireless encryption as the new one, match the wireless ESSID (name) and encryption password (And type! Such as wpa2) so that they appear as the same Wireless network (distributed wireless) and the easesst and most supported method is to then link the two devices via ethernet and place one of them somewhere else in the building where it can provide a signal in the blindspots of your primary superhub.
Also a side not.. If i recall, the most recent superhub uses 802.11n on 5GHz, which does not boad well in old victorian houses, and new ones made with lots of metal strips between plaster boards.. 2.4GHz works better at penetrating walls, so check you dont have this option set to 5GHz under the wireless settings.

Ok i will check all that out soon as i have time but thanks also. The house is made in 1970's it is strange that im not getting good signal in the garage room the wireless hub is situated in the living room downstairs then theres a brick wall then the hall way withthe stairs in the middle another small brick wall which leads to the garage room. I get signal but its poor. Would a netgear wifi extender work the one on the net for about £40 if the super hub 1 idea didnt work?

Yes, any off the shelf Signal "Booster" device should work, I use one at work and it's essentially a small WiFi device that connects to a specified Access point (in your case the super hub) and re-broadcasts the same network settings from it's own wireless card, forwarding any data to and from the original access point like a wireless bridge. the only down side is there is usually a slight decrease in bandwidth with this method, where as using multiple wireless access points, hard-wired in to a network via Ethernet all have their own dedicated connection providing maximum bandwidth. Hope that helps and isn't too technical

I full understand, soon as i get some spare time i will try the settings on the hub etc, if no luvk with that then i will look towards on getting the wifi extender preferably the netgear with two sntennas on for £40, i did hear that that one is only 2.4ghz. Oh well fingers crossed somthing works.

If im not mistaken again (the VM Superhub in my experience is the one at the office) it broadcasts on 2.5 and 5GHz simultaneously, so you may get away with it, the repeater would use the 2.4Ghz band for it's distribution link, and any devices close enough (and supporting) could use the 5GHz band, which in theory would work in your favour, and not effect the repeated signal, giving you a little boost in performance.. this, of course depends on how well the superhub manages its wireless, and i have little faith in it as it is..
