IP Address - Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl

Does anyone know why in certain places, the tablet cannot connect to wifi? It is searching for the IP address, but cannot connect. I am sitting next to people who have IPADS and laptops and they can connect without a problem. How can I fix this?

[Q] Problem with wifi and 2wire 2701HG-B modem

Hello
Is there anyone out there that know why my I phone can connect to my 2wire
2701HG-B and it gets an ip address but it will not connect to any web pages. I can see all my computers on my local network but that's it.
Thanks
Mark
Well found the problem. Just give it a static ip address..

wpa2 issues

anyone else not able to connect to a wpa2 wifi network?
mine connects but there is no internet..>.>
figured out my own issue, apparently my router was giving my phone a different ip than the phone wanted, so all ihad to do was assign the ip my phone wants from the router manually.

Failed to obtain IP.

So, weird thing started to happen last night. Both my Samsung devices ( my 2014 10.1 and my S4) started failing to get an IP from my wifi network. It would see the wifi network and report a strong signal, but would fail at the obtaining IP address. The IP assignment is handled by a Windows DHCP service running on a domain controller. I work in IT so I have a fairly extensive lab at home with routers, switches, servers, domain controllers, etc. The wireless access point in my home is a WNDR3700 with no WAN port config as my firewall/routing is done by a Cisco ASA 5505. All the 3700 does is provide wireless access to the network, essentially it acts solely as a wifi AP. Every other wireless device on the network is functioning fine including 3 laptops, a Blackberry and two other Android tablets ( Asus Transformers). So I know nothing is wrong with the dhcp or the AP in general. It's not a security issue as it is not failing on authentication, just on obtaining IP. So as a workaround I configured each one with a static IP and, of course, everything works fine.
One thing I noticed that seemed odd was that when I went to change the IP addr the address that was already in there, but greyed out sort of, was the wrong network for my home wifi. The phone and tablet both looked like they had a 192.168.1.0/24 address whereas my home wifi segment is 192.168.0.0/24. So maybe that had something to do with it. At the office now and both my phone and tablet have no issue connecting to our Cisco APs and getting a dhcp config from a Windows DHCP server. So pretty weird situation. I'm fine with leaving them on static config while on my home wifi network. Was just wondering if anyone else has seen this before?
Thanks
For any that might be interested. I used inSSIDer to find a less crowded channel for my 2.4 ghz band at home and both my Samsung devices are connecting and receiving ip addrs now.

[Q] Is there a way to unblock inbound traffic?

I cannot ping my IP while tethering on my phone. Is there a way to unblock inbound connections on the site, or is it a phone option? There are apps to do this, but they all say you need to be able to ping the phone, and I can't.
I use my phone's tethering as my main internet while at home (unlimited plan) but can't host any games because no one can connect to me.
Still not a thing? I can't ask anywhere else due to the post limitations.
While your computer is tethered to the Internet through your phone, what are the IP numbers of the phone and of the computer?
What IP number are you trying to ping, and whence?

The current IP for all computers connected to my phone is: 70.194.2.149
Using that IP I cannot host any games. Though for some reason I can on PS4, so I have no idea what's going on there.

Every ethernet port, wired or not, has an IP address. Two devices cannot have the same IP address, each address on a network has to be unique. 70.194.2.149 is the (public WAN) address of a single device, probably that of the incoming port of your router. Your computers each have their own IP numbers (typically in the 192.168.x.y numbering scheme). Your router also has an address in that same number range, for use on its inside (private LAN) ethernet connections.
I don't want to write a dissertation on NAT (network address translation), but that is what the router performs so that your browsers or your Telo "appear" to be coming from 70.194.2.149. Net result,as far as your computers are concerned: they can call out, intitiate a connection to wherever, but nothing can initiate any contact to them from the outside world (short of doing some "port forwarding" in the router). Look up NAT iand port forwarding in a search engine.
BTW, what is "PS4"?

Playstation 4. All of my PC's connect to the internet through my phone. There is no router, there is no ethernet. They all share the same IP because that is the IP of my phone (my best guess.) That is why all the targeted ads are from the same town. I don't know where in my first post, or any there after you gathered that I am having issues with a router.

Ah, OK. Then it is your phone which is acting as a router and is doing the NAT procedures. I don't know how to make a phone forward specific IP ports to specific IP addresses.
You need a port forwarding app to allow incoming traffic to reach the right device on the network.
Forward what ever port(s) your game uses from the public wan ip to the game consoles ip provided by the phone.
So lets say forward port 1234 (or all ports) to 192.168.1.10, or what ever the game consoles ip is.

That would work, only all the port forwarding apps require that you be able to ping your public IP. I cannot, all packets are lost no matter what method I use. I would call and ask Verizon, but I have unlimited data, and there is no way I will let them weasel that out of me.

[Q] Unable to Connect to WiFi

Here is a head scratcher...
When changing the IP subnet from 192.168.1.x to 192.168.2.x (or any thing else for that matter) the HTC One M8 will not connect to the WiFi. It will only connect when the subnet is 192.168.1.x. All the other devices - even an iPhone - work without issue when moving them to the new subnet. Everything on my LAN uses a static IP address. I assign them all myself and write down what devices use what address.
Does anybody know how to fix this? The phone is 100% factory and it is not mine, so rooting is out of the question.
