[Q] Why does my phone take up 3 IP addresses - Verizon Droid Charge

When connected to WIfi at home , DHCP allocates 3 addresses to phone
192,168.40 , 104 & 118.
Curious why this happens.. Descrete aps communicating through different addresses ?? I thought that is what ports were for

That doesn't even sound possible. Are you sure they are all your Charge? Could they be other devices? Are the MAC addresses the same, or even similar?

Yes-- I have a program that scans the network and assocciated mac addresses.
The fact thet they were all the mac address for the phone is what started me questioning..

I have to agree with shrike. Doesn't seem plausible. some routers will keep a log of previously connected devices, and so they show up in the lan dchp pool list. But to have one device using 3 ip addresses at once... Not likely. You could try to ping each ip address from a computer on the same lan, to which I'm pretty sure 2 of those ip addresses time out.

Sounds like a plan

Last scan revealed 4 addresses but only one returned a ping..
DHCP pool I guess is not releasing some addresses

If your phone can connect to the internet and only one ip returns a ping, then dhcp is in fact releasing the other ip addresses. Something must be messed up with your program.

Could be.. It is a piece of freeware called advanced IP scanner.. (it is not very advanced)

Why not just log into your router and see what's going on, then rely on some freeware program that may or may not be accurately showing the proper ip addresses.

Two HTC Desires on 1 router?

Hey, im having trouble connecting my htc desire to my home router, im almost 100% certain its because my roommates desire has the same MAC address as mine, meaning the router blocks one. So i tried changing my MAC address using the "ip link set eth0 address XX:XX:XX:XX:XX:XX method on terminal, but after i change it (i checked, it does change), the router wont even connect to my phone, and it gets stuck on "applying ip address". Also when i turn wifi off on my phone, it changes the MAC address back to the original.
I have looked around a lot and foubd no solution, so please help would be very much appreciated
MAC addresses are unique, so there would have been no need to change it! I'd say leave it reset back to what it was for now.
Have you tried restarting both phone and router? Maybe the router is set to only allow certain MAC addresses. You'll need to add your MAC address to the router in that case. What router is it?

Its a BT 2wire router, i have tried all kinds of stuff like resetting both to factory conditions etc. Iv never tried adding the mac address to the router, though that sounds like it could work.
I thought mac adresses were unique too, but ours say they are the same in hardware information on the phones settings.
How do i add the MAC address to the router?

MyCloud/Splashtop = Outside Home Network?

Can I use 3G or say my schools wi-fi to access my home computer?
If you're tethering from 3G, just make sure you portforward your router, and just put your external ip in the settings. Google ipchicken to find out your external ip.
Interesting.
But any idea how do I make my IP fixed?
It seems that the external IP changes whenever I make a new tether connection.
BTW, which port should I forward through?m My 2wire router ask only for the tcp/udp port for forwarding, it does not require me to key in any IP address.
Can you advice?
thanks.

To work around the dynamic external IP address you can set up a free account at DynDNS:
http://dyn.com/dns/dyndns-free/
The above link will set up a hostname for your IP address and when it changes, DynDNS will automatically update.
To forward the correct ports, go to the website below and choose the router model you have and then select "Splashtop Remote" from the list after that. (You'll get redirected to an AD, just click skip ad at the top right of the page)
http://portforward.com/
If you already know how to forward the ports, they are 6783 to 6785, both TCP & UDP
Splashtop can sign into a Google account and find itself regardless of networks. I've had no troubles hitting my computer from miles away using that method. Being said I nixed my loud and bought splashtop HD, easily with the money.

This is the best method, and easiest. I used my above solution when it wouldn't work with my Gmail account. But I already had DYNDNS set up for my media server so I only had to forward the ports.

Just a note/caveat they are correct that, no matter what, you are going to need to make sure your route is setup to make your computer connectable on those ports. Otherwise its just going to block the traffic thinking its malicious.
I have run into connectivity errors on some networks because they also block traffic on non-common ports, so if you occasionally cant find yourself that could be it.
thank guys!!
very infomative!
I tried everything.
I forwarded ports on my router.
Disabled my firewalls.
Changed to Static IP on my computer, then router, then both.
Made sure the ip was outside DCHP range.
Rebooted after every change.
Tried DynDNS, but I must be stupid because there's no way to enter a host address in splashtop.
Tried using external programs to set a static internal ip.
Set Splashtop to external/internal IP.
I don't know what the hell it is, but I just can't get this nonsense to work. I don't understand what's so easy about this for some people. I have comcast cable modem attached to n300v3 router over WAN, and nothing I try works. Been at this for 3 days. Time I quit.
Are you doing the google account link? That, along with making the ports pass through on my router, was all I did. Seriously, that is is. Comcast/xfinity with a belkin wifi router.

Problem with Wi-Fi on a MESH system

Hello everyone
I just installed a MESH system - Tenda MW6 (two nodes connected to the main router, dhcp is on the main router).
I'm having a problem with the LG v30 running stock 9.0
The phone connects fine to the wifi network, but 90% or the time there's no internet access, when all other devices are working fine.
Is there anything I can do to make it run properly?
Thanks
Sent from my LG-H930 using Tapatalk
UPDATE
it turns out that this happens only when u turn on the secondary node. If only the main node works, everything is fine
It seems that the phone keeps changing connection to the nodes causing this.
Any idea about a possible solution?
I'm still suffering from this issue
Any ideas maybe?

Have you set the mesh network up properly??
You don't want to have them set to DHCP.. That is just foolish (not insulting you).
Allow me to explain it as simply as I can..
You don't want to have the access points set to dhcp whilst connected to your router or you'll run in to "double NATing" conflicts..
Give each of your mesh devices static IP if possible, and set the default gateway of your second node to the routers address (example: router IP 192.168.1.1 <---- that IP address will be set as the default gateway on your second node.
I assume you aren't bouncing both nodes off of one another right?? You should simply have both nodes set up as individual Access Points..
So like. Router-node1-router-node2.. And not router-node1-node2..
Hopefully that made sense. let me know how you go
****edit****: sorry I should have asked this first... Which pack do you have? 3pack or 5 pack?? And was your MAIN router one of the 3 Mesh Nodes?? Sorry about that. Once you provide that info. I can help you with your problem fairly easily

The dhcp server is still on my main router and modem, I preferred that because the Tenda mw6 limited security settings. The Tenda are set as Bridge mode.
One node is connected with ethernet cable to the main router, and the second node is set in another room.
Does that answer the question?

Yep..
Now.. Have you changed any any SSID settings?? One thing I want you to try is to hard reset the node that you're having the problem connecting to the internet with.. I assume you're using the APP to configure your network yes?

Cannot access local lan web site (sometimes)

I have various machines on my lan in 192.168.1.*, I have a local DNS server to give those machines names. This normally works great, but my new Samsung Galaxy S21 sometimes says "cannot access" when I point it at a web address of a server running on my lan. I'll use a network utility app to do a DNS lookup of the other system, and it will tell me the correct address, then I'll use the same network utility to do a traceroute, and it will try to talk to a local IP I do not have in my network, in my DNS database, or anywhere in the set of addresses my router knows about. Where does this ghost address come from? Does the phone imagine that is the gateway it ought to be using for some reason? (The router's DHCP server certainly doesn't claim an unknown address is the gateway).
Every time I start trying to investigate the problem in more detail, everything suddenly starts working perfectly.
Does this ring a bell for anyone? Any clue what is going on? Maybe I should assign my phone's network statically and see if it works better.

Assigning a static IP address to a phones hotspot

How can I assign a static IP address to my phones hotspot?
I use the hotspot on my Samsung M31 to connect my laptop running Windows 10 to the internet.
I also have Oracle's Virtual Box VM running a few test websites on the laptop on Ubuntu Server 22.04, which need a static IP address to access.
A few days back when I ran ipconfig at the Windows command prompt, it showed my wireless IP address as 192.168.166.135. Today, it show as 192.168.35.125. Meaning, all my sites are now broken. Is there a way to stop the hotspot from changing IP addresses?
Can someone please help?
Thanks,

I don't know the answer to your question directly as your situation is more complicated than is mine but I will try to help in so much as you can at least check what your current settings are.
My setup is only similar to yours in that I have apps (such as vysor & scrcpy) on Windows which are expecting a static IP address from my phone. However, where my setup differs from yours is I'm not using my phone as a hotspot - the router is assigning the IP addresses.
However, maybe what I've learned by randomizing my MAC address on each connection can help you - where I say maybe - as I your situation is using the phone as a hotspot and mine is passively accepting the IP address handed to the phone by the router.
In Android 11, the phone's Wi-Fi radio MAC address can be randomized per SSID, in which case the "address reservation" feature of most routers (often incorrectly called "static" IP addresses) won't work as intended. Worse, in Android 12, in Developer options, you can set a switch to randomize the Wi-Fi radio MAC address of the phone on every connection, regardless of the SSID.
Hence, you have to set the "static" IP address request in the phone itself, so that the router will respect that request for a static IP address.
(As an extra complexity, my SSID broadcast is hidden for privacy reasons (not for security - but privacy), which complicates things only a tiny bit as you have to turn off auto-reconnect for privacy.)
See the images below where maybe (but maybe not!) this information will help you track down why in your (hotspot) case, this static IP address requrest isn't being honored in your hotstpot setup.

To assign a static IP address to your phone's hotspot:
Go to your phone's settings and find the hotspot or tethering settings.
Look for the option to set the IP address as "Static" or "Manual."
Enter the desired IP address, subnet mask, gateway, and DNS server information.
Save the settings and restart the hotspot.
