First of all, I have internet from Time Warner Cable and it came with a router/modem all in one. Now that was initially set up and that works 100% perfectly with my SGS2. Since I have a weak WiFi signal upstairs in a couple of rooms, I decided to hook up an extra router that is set up as an access point. The second router is connected via a cat5e lan to lan to my main router (home is wired with cat5e connections).
Now on the second router, I have disabled DHCP since the main router is responsible for that. On the second router, I set up a different SSID first to test it out. All wired and wireless connections worked great through my laptop/Xbox 360, PS3. My SGS2 connected fine as well and worked.
Now the issue is that the SGS2 "drops" the WiFi after some time. Sometimes it happens after 5 minutes, sometimes 30 minutes, etc. Even with the SGS2 right next to the router it happens. Meanwhile, my laptop stays connected the whole time.
I can't seem to figure out what the issue is now. I've reset the second router a couple times and set it up all over fresh but it doesn't fix the problem. Seems to be a problem with my brother's Sensation as well. Is there something with Android and access points or going through a second router that causes issues? Any other settings I'm overlooking? SGS2 connected to the main router stays connected until I turn WiFi off. But to the access point, it drops out after some time.
FYI: Second router (access point) is running DD-WRT firmware.
If you need any other info, just ask. I'll be home from work in a couple hours. I've been messing with this for the last 2 weeks but nothing seems to work. Please help! Thanks.
Hmm thats very odd. Im running a similar setup as you, except my main and 2nd router connect via 5ghtz N.
Have you tried statically your phone with an IP address then modifying your main router (that gives DHCP) to reflect that IP is permanently assigned?
edit: to hard set your phone...settings-->wireless and network-->wifi settings, then menu key and advanced. Just fill in the IP and gateway info, and obviously use something in your DHCP subnet. You'll have to look at your DHCP subnet, but you'll probably use 255.255.255.224 as your mask, and use your gateway (your main router IP) as your DNS.

Try giving your phone a static IP from your main router. Also make sure that you adjust your phones wifi settings under advanced settings so that your phone stays connected to wifi during sleep. Hope that helps.

Well my phone is getting the same IP address each time, whether I connect to the main router's SSID or the second router's SSID. But I will try this static IP. One problem is that I don't know how to find out my DHCP range. There's nothing in the main router's settings about the range. The second router has an option to set the IP address range for DHCP but the main router doesn't. See attached image.
I'll try to set the static IP around what the IP addresses of other devices on the network are since I don't know the exact range. Let me know if I'm doing this wrong. Not sure what you meant by 255.255.255.224 there.
The static IP didn't make a difference. Still keeps disconnecting/dropping after some time. Meanwhile, the connection with the main router stays connected. Don't know what else I can do. Seems that my HP Touchpad running CM9 stays connected to the second router without dropping. Don't know what's different about that from my phone.

Does anybody have some instructions on how to set up the second router as an access point? I'm pretty sure I set it up correctly but apparently there seem to be some issues. People who have a similar setup that can help would be great.
Main router from cable company with built in modem where internet connectivity comes from is downstairs. Connect cat5e from LAN of main router to LAN of second router upstairs. Second router set up as access point for better WiFi coverage upstairs.
2 options for second router: DD-WRT D-Link DIR-615 or D-Link DIR-625.
"Could" buy some other recommended router for this and try that if needed, but would definitely prefer to use what I have and get this to work.
This might be completely off but I had a similar issue with my SII when connecting to 802.1x networks at my University. I downloaded this app called wifi fixer and it resolved the wifi connection drop for about 90% of the time. Give it a shot, it might do wonders for ya.

I tried it and it didn't work. I think it's something to do with DHCP or some other settings.

First you need to find out if your router is supported. According to the DD-WRT database, the 615 is, the 625 is not. But there are several revisions of that router, so you need to find out what revision you have. It should be on your label.
Router database
Then you need to decide whether you want a repeater, an access point, or client bridged. You can read the differences in the DD-WRT wiki found HERE
Then you need to find the best build to flash to your router. I suggest reading the overview of the 615 found HERE. Read the ENTIRE thread. If you flash the wrong version to your router, you WILL brick it.
Then flash the appropriate firmware, set it up, and youre done. Youre going to have to do some reading.
edit: I would also suggest downloading wifi analyzer on your phone and do a site survey of available channels in your house. Most likely you WILL have interference from neighbors. Youre going to want to hard set your channel to the least congested channel, either 1, 6, or 11. Once you get DD-WRT set up on your 615 you can do a site survey within the router as well.
change the channel on your router to 6 not 11 i had that issue with our second router and actually my nook color. Depending on the router it should be under wireless settings.

The only reason to use one over the other is congestion. Thats it. And you want to use 1, 6, or 11 because the DIR615 has N capability, and you need a wifi primary channel to use N. Theres only 3 primary channels...1, 6, and 11.

I have actually done all that. The DIR-615 is an E1 version and I flashed the correct DD-WRT firmware on it. I followed a tutorial from the DD-WRT website to set it up as an access point as well. My laptop works perfectly with it. Just my phone keeps dropping the connection from it. My main router is on channel 11 and the second router is on channel 6. I also tried channel 1 but it didn't help.
I might just to try set it up as a second router on a different subnet than the first router and see if that helps. Going to try to follow this Youtube video and see how it goes.

Hhmm ok. Well your main router shouldn't have anything to do with it. When it drops does it re-aquire an IP and reconnect? Honestly if a reboot of the router doesn't fix it and your laptop doesn't have the same issue, its pointing to the phone.
Maybe a factory reset?

It reconnects when I unlock the phone. Sometimes I have to reset the Wifi on the phone. Have set the Wifi connection to never sleep. My brother's Sensation was doing this as well. I'll have to test it out on his phone and see. I'll probably reset my phone later today and see if that works.

already set "always on"...never change from got GN...so i don't understand why i got this issue with all my netgear router...my dlink/tp-link works fine...but they all broken...thats why i replace them to netgear...:crying:
One quick thing to look at, that seems to pop up now and then, what's your DHCP lease set to? Setting to '0' (that should be forever) doesn't work as well for some chipsets it appears. If you just have bad luck getting/keeping a lock on your router, try changing the dhcp to something else, 2 weeks ish? Play with it.
Might be something else entirely, but after having seen this 3 times now, it's worth a bash.

TKS for replay...seems netgear wndr3800 not allow change the dhcp lease set...there are not option about dhcp lease set...and as my custom...i have set the gn as a static ip...so it may not be effect to the dhcp lease set...both wnr612 v2 or wndr3800...all of them not have option to set dhcp lease...
What type of connection are you using on the wndr3800?
2.4ghz, 5ghz?
And what channel, since you have two routers, make sure they're on different channels and opposite, set one to 1 and the other 11 or 6.
Also what type of security? wep? wpa2?
Try using 2.4ghz, i found the 5ghz isn't very strong/good with gnex.
Also you can try with NO security and see if it works better.
...
worse comes to worse, reset your wndr3800 back to default and regular dhcp no static, no custom settings for anything and go no security on wifi or go wep.
...
Also, since you have 2 routers, you have them set so that only 1 is doing the dhcp and the other is turned off right? you can't have 2 routers doing dhcp.

i worked round it by not using DHCP on the phone, change it to manual setting and assign an IP (or keep the current setting) to the device (long press on your connected wifi, then choose modify; for some reason adding new connection only accept DHCP by default). need to do that at the router end as well, edit the lan setting and record the phone MAC address to that IP. someone on another thread mentioned, if my memory serves me right, that GNex can have wifi issue with some routers' DHCP setting, causing it to drop connection when new lease was issued, and this is the reason why i choose not to use DHCP.

My main router is my FiOS router, that does all the DHCP, I have one of the ports plugged into my WNDR3700's port (not WAN port), I use the WNDR3700 for all WIFI devices.
I have DHCP turned off on the WNDR3700
Basic Wireless Settings
Both 2.4GHz b/g/n and 5GHz a/n I have SSID broadcast on, and set to Up to 300Mbps.
2.4GHz set to Channel 03, and 5GHz set to channel 36
I use WPA2-PSK [AES] for both radios.
In Advance Wireless Settings, it's all default.
Both 2.4GHz and 5GHz are the same:

CTS/RTS Threshold: 2347
Preamable Mode: Automatic
Transmit Power Control: 100%
That's it, I do have MAC Address Filtering too, but that shouldn't matter.
Again, everything else is default.

Among wifi disconnecting at times I'm seeing another issue. I have 2 modems in the house & easiest way was to join the networks. When setting the Note to use a static IP address and gateway some apps will not go online yet the browsers work fine as well as gmail. YouTube app is 1 example of it. It won't play videos when set to manual settings only DHCP assigned.

sounds like your LAN isn't setup properly. First, I'm assuming when you say two modems, you have two different ISP feeds I'm assuming you have a more advance router than the stuff you buy at the store, or some custom firmware for it. The off the self routers can't handle that. If I were to guess, your router is not handling to two IPs you get from the ISPs well.
Beyond that, it sounds like you're having some kind of firewall issue. Check your firewall logs and see if any traffic is being blocked to or from the static IP you're assigning the GN2. I tried the Youtube on my GN2 on my LAN and it worked fine. I use Smoothwall 3 as my router/firewall. I have to open a ports for both inbound and outbound traffic for various services.
Yeah the 2 routers: ATT uverse modem/router & a dlink-dir825. The dlink doesn't have a custom firmware for it as it's rev A. They only have it for rev b or newer.

Recently though the Ethernet cable has a break in it. So now using a dd-wrt flashed AP in a bridged mode. Works but it seems to slow the whole network down even between devices on the same segment. So I only turn it on when I need it.

Hello,
I recently purchased the Note 8.0 and I'm experiencing a weird problem with the internet connection. I can connect to my wireless network, I can access other devices on the LAN, but I cannot access the Internet or ping the gateway (I can however ping other hosts on the LAN). I know it's not the tablet as I've tried it at work and I also tried running my S4 as a hot-spot and internet works as it should. The S4 works without a problem on my wireless at home as do a few laptops.
At this point, I'd say, it is obvious that it's something with my cable modem/router, but if possible I'd like to figure out what the problem is.
I found a post somewhere that had a similar problem, where the device in question was receiving the wrong MAC for the gateway, but this is not the case here as my tablet does not even receive a MAC for the gateway.
Output from the tablet:
android:/ $ ip neigh
<some IPv6 address> dev wlan0 lladdr <Gateway MAC> router STALE
192.168.0.1(gateway) dev wlan0 FAILED
192.168.0.5 dev wlan0 lladdr <Server MAC> reachable
Output from the S4:
android:/ $ ip neigh
<same IPv6 as above> dev wlan0 lladdr <Gatewawy MAC> router STALE
192.168.0.1 dev wlan0 lladdr <Gatweay MAC> reachable
192.168.0.5 dev wlan0 lladdr <Server MAC> reachable
I've tried resetting the modem back to factory defaults, removing/changing encryption type. I did not wipe the tablet as I've had the issue from day 1.
The only way I'm able to get the tablet to sort of connect to the internet is to assign a static IP to it, however that only works for a few mins and is very intermittent.
Does anyone have any suggestions? Any way to figure out why the tablet won't get the MAC for the gateway?
My cable modem/router is an Arris DG860, but unfortunately, there's very little info on it and I couldn't find a firmware upgrade for it. What's also interesting is that the tablet does not show up in the DHCP client list of the modem, however it gets an IP, connects and communicates with other hosts.
Thank you for your help
What IP is the Note 8 ending up with? If somehow it is outside the range of what it should be I would wonder if it is just giving itself an IP when it fails to receive one from the DHCP server (ie, your router). I know that Windows computers will do that as a fallback.
Can you check your router to see if perhaps the DHCP pool is too small? If that were the problem then it might not be allocating another IP because there aren't any left (based on it's current config). In which case you can just make the number of allowable IPs to be larger.
There may be other possibilities too. The above are just what is coming to mind at the moment.
It is a valid IP as I have access to other devices on the network, but to answer your question it gets 192.168.0.13 with a mask of 255.255.255.0. I wanted to try forcing the private network to work on IPv6, but haven't been able to figure it out yet.
The tablet gets the right MAC for the server and communicates with it, which leads me to believe that the router (gateway) isn't responding to ARP requests from the Note. I have some access to the router's CLI but it's not very helpful and I have no idea how to troubleshoot it on the Note..

That is bizarre. Can you ping the gateway from other devices on the network? Can other devices on the network ping or otherwise see or access the Note 8? It seems like the Note 8 doesn't exist to the gateway, and so I'm wondering if it also doesn't exist to anything else on the network. It is possible (though I'm just guessing here) that the Note 8 is giving itself an IP address that it determines as being appropriate based on the other devices it can see. Given that it doesn't show up in the DHCP table on the gateway I can't really see how it is getting an IP unless it is assigning it to itself. Another thought is to check the IP addresses of all the other devices currently on the network in case somehow you're having an IP address conflict (ie, two separate devices ending up with the same IP somehow, which can happen temporarily in the case of a device having an IP and then being hibernated, during which another device is given the same IP, and then later the first device is resumed from hibernation).
If you don't receive much further help here on the XDA forums I'd suggest starting a thread over on the SmallNetBuilder Forums as there's lots of knowledgeable folks there that can help with networking things like this.
As for me, I've got to sign off for the night. Best wishes to you as you troubleshoot!
Hi and thanks for the reply.
Yes the gateway is pingable from other devices, so is the Note. I also tried changing the 192.168.0.xxx to 10.10.0.xxx with no luck. The Note received the 10. from the DHCP server, but the gateway still would not respond.
I think it might have something to do with the routing on the modem, the hosts on the network can communicate at layer 2 (no routing need) while everything on the outside needs to be router. Still does not explain why the gateway doesn't respond to the Note though...
Have you done a traceroute to another local device to see the path its taking?
You will need to have root and I think busybox. You will also need to su before doing traceroute... maybe there is an app that can a trace if your not rooted!

What is your network diagram with models
(I.e note 8 > router(wrt54g) > cable modem)...

I am not able to run traceroute from the tablet, I tried it from my desktop and it completed, but never hit the gateway - it went right to the host.
the network model is
note8--->all-in-one-wireless cable modem

Is the router still left with it's default settings? Also, Is there a page in the router/modem's web gui for DHCP and if so, what are those settings? It sounds to me like the DHCP is failing to pass along the external GW and/or DNS servers. To test a theory, are you able to ping 8.8.8.8?
I wonder if this was solved? I'm having the exact same problem minus all the technical knowledge. Tech support at time Warner seem like they are reading a script. Has anyone found a fix or workaround for this modem? My note works everywhere but home
I might have narrowed down the issue...
On technical support last night it was resolved that the Note was looking for IP version 6 ip and the time warner box only outputs IP version 4...
Is there a way to have the note look for IP version 4??? I know nothing about this but I guess over this next year we are supposed to be switching to IP version 6?
I unpacked my note 8 yesterday and I experience an issue when connected to wifi. When I tried to download something from play store it taked too times and usually downloads remained blocked at 70/90% and this didn't happen in 3G. So I tried a factory reset and now all thing works great you could try..

Factory reset doesnt do it for me.
My wifi works everywhere but at home using Time Warner on the Arris DG860 modem. I think the OP and my problem are because of a combo of these factors.
I believe it has to do with the IP change that is taking place this year.
If you look up online it seems to be kind of a big change. You can type ... time warner ip version 6... into google and see a link that explains it. I cant link for some reason.
I wish someone could confirm this, but does the note 8 only accept IP version 6? Time Warner will only deliver version 4 to me right now through this modem, and the tablet is making a version 6 IP.
Atleast thats where ive made it so far.
I can confirm that I have the same problem at my In-Laws house. Arris router, and Charter network in Louisville. Likely the same as Time Warner folks.
But I think the Arris router is the more likely culprit. I didnt feel comfortable asking the FIL to let me kack around in his router :laugh:
I have the same problem on my main wifi at the house. It's a 2.4/5 ghz setup. My guest wifi is just normal 2.4 different router etc. I'm going to need to look into this at length as this just isn't going to do. Also as far as IP6 is concerned we won't see that roll out Internet wise for at least another 2 years fully. When it does go full steam all of the IP4 routers APs will have to be either replaced or firmware upgraded if the internal radios will even support IP6. Most likely 70% won't and that's the reason you don't see a lot of IP6 routers etc. We have them on the enterprise side but most are not in use. I will report back when I have anything useful.

OK figured it out and it includes a bit of funny.
I went through my network setup and forgot that I had
MAC filtering on so I added the Note along with a face palm thinking
That was it, couldn't have been that easy right... No it wasn't but good
News.
The note 8 doesn't like the 20/40 "channel width" or some routers call it "wideband" in the routers or in my case access points. Turn that to 20 only and boom there you go. Wifi
Works perfect. You will find it typically under advanced settings.

The Note 8 supports both 4 and 6. The issues described sound a lot like config issues on the modem or router. as stated before, sounds like an issue with the DHCP server (the thing that provides ips to the devices.)

Hmmm I have an ipad, note 2, ps3, laptop, gfs iphone all connecting just fine... hours and hours of tech support, and the best answer is incompatability. For some reason the note is only creating ip6 my isp only does 4. I understand the note is capabale of both, but in this specific instance there is a bug in the note with this router.
nothing to do with settings. If every other device I own connects without hassle then someone needs to fix the note 8. Christ my note 2 connects....
there were no options untouched by highest level tech person fromisp... its the note 8
Arris DG860 and Note 8 *Workaround*
Ok, just got done trouble shooting a customers Note 8 on working behind one of our DG860 modem/routers, what I was seeing was the Note 8 was showing up with an IPv6 address even if I had the IPv6 DHCP turned off. What I found works is if you go into LAN > DHCP on the DG860 and create a "Fixed DHCP Client" using the Notes MAC address and some address in the IPv4 range like 192.168.0.X it will force it to pull that instead of the IPv6 address and work. Hope this helps anyone running into this weird combination.
At wits end
I been having nothing but issues connecting my wifi only note 8 to the internet at my house. Everywhere else it works fine but at home nothing but issues and all other devices are connecting with no problems. I have tried it with a netgear router, and now a arris gateway and still cannot connect. The cable tech came out by chance and was checking my connections and could not figure out why it would not connect either. I have time warner if that makes a difference which I am starting to wonder it does seeing how I can connect everywhere else and have tried two different ways to connect at home.
Update: So after being on the phone with time warner, samsung, and live chat with Arris this is just one hot mess. Samsung is stating that there seems to be firmware issues with arris gateways which I have noticed many people posting problems with their arris products, and their resolution was to roll back the software. Time Warner is stating that they cannot roll back the software on the modems and was trying to blame it on my tablet, though it was working before I setup the gateway and it works on other routers even on a piece of crap belkin that likes to kick off everything it worked on that with no issues. Arris told me that they have no control over the software only the cable companies do, so in typical fashion a lot of passing the buck and finger pointing. I am just irate at the moment for I do not have a working tablet at home. Part of me thinks it is the android 4.2.2 as well, for I had 4.2.2 on my droid razr hd and had numerous wifi issues with it.
Update 2: After doing some more research I have found there seems to be a issue with the wifi card and the chipset with arris gateways so there is a compatibility issue with the card. I had my netgear hooked up to it before and didn't have issues so I am going to just use my netgear and run the gateway in bridge mode it should fix the issue.
At some points in your life, one of your Android devices connect to a wifi router, but can't connect to the internet. However, your computer, laptop or iPad will connect to that same wifi and use the internet just fine. I've looked everywhere on the internet for solutions, some of them are:
+ Turn off and on both modem and wifi router
+ Factory reset wifi router
+ Battery pull your phone, wait 30s and put it back
+ Reflash stock or custom ROM
+ Change DHCP IP setting to Static
+ Disable security (WEP, WPA) on wifi router
+ Check DNS server, gateway IP address for correctness
Fortunately, I stumbled upon this old thread last night -> http://forum.xda-developers.com/showthread.php?t=1371794
It helped fix the internet connection temporarily, turning off and on wifi on phone caused the issue to repeat.
In summary, he found out the correct MAC address for gateway was mismatched with the one on his phone. Even though the gateway IP address is correct (example: default gateway IP 192.168.1.1)
Upon further investigations, I found out my Wifi ROUTER has the same IP address with my MODEM (192.168.1.1) This IP conflict causes the phone to recognized the WIFI ROUTER's MAC address as the gateway's MAC address. This problem mostly occurs on Android phone, not computer (I'm no tech savvy so I have no idea why)
Simple fix: Go to wifi router setting page, change the IP address on wifi router to different number (other than default 192.168.1.1), and the problem should be fixed.
Please help spread the words to fellow Android lovers, I'm sure a lot of us have struggled with this problem :laugh:
I'm one guy who is desperately looking for a solution to this.
Unfortunately the solution you gave didn't work.
Hi
i have a problem with wifi. it remains connected but loses internet access randomly. i found this solution:
"In the wifi networks, select the network you want and select ‘Forget network’
Turn off the wifi
kill all the apps with your task manager
Turn on the wifi again
Connect to the network
Check the internet connectivity
If still the problem exist, switch off the phone and redo the above steps"
it solves the problem, but it happens again after some minutes. actually, i also installed an app named "wifi fixer" which does the above process automatically. when the program is active, it turns the wifi off and on every 2-3 minutes. and the phone has internet access when the program tuns the wifi on.
any idea?
Turn off wifi optimization on some android phones help.

(bump) By any chance, are you all using Aztech's router? I have the same problem with my Aztech router.

2 years after the last reply I am having the same problem. My wife and kids all have internet access on their phones, tablets, desktop and laptops all from the same modem router yet I am unable to use the internet on my Galaxy S2 mobile phone even though my phone says connected to Wi-Fi Network Netgear 06.
The Mac address solution provided isn't applicable to my situation as my Mac address on my mobile is different to my modem router Mac address.
Any other solution?
