Where do I set the LAN Computer Name in the Captivate - Captivate General

Where do I set the LAN (WiFi) Computer name in the Captivate. My router has functions that require either the host name or the IP address of the host. Using the host name for DHCP clients makes it a lot easier to configure some of these settings. The way I'm currently doing it by reserving an IP address for the MAC address of the Captivate WiFi NIC.
I can see where the host name can be changed for Bluetooth, but not for WiFi.

Good question, I dont know. So far from what I've seen when looking in my wifi router while connected, the phone doesnt have a "name". The name field is just blank, all it shows me is the mac address of the phone, and the IP address assigned to the phone.
I've looked under wifi settings and advanced wifi settings and dont see anything.

Another wifi problem.

Hi everyboy, I have an Blue Angel with WM6.5.3 from sun_dream. I can't connect to my home wifi or any wifi. I configured my router like this:
DHCP off
Wirless all
WPA-PSK
TKIP
64bit
I can't connect even to open wifi accespoints(hotspots).
I start the wirelss manager, tap on wirelss on and after that the wireless network appears. I click connect and nothing happens. In the network manager the connectios is available, i click connect, it says connecting and than again it says available.(any hot sopt or the home network, for that at home i entered the mac into the router and have written the ip an dns to the phone wirelss card)
Pleas help, it is a great phone i like it but this is the only problem i have.
PS: I even commanded an bluetooth gps unit. Is there any way to change the hardware and install an "g" wireless card?
Shouldn't DHCP on your WiFi router be set to 'On' and also for the phone as well. It will select an IP address for your device, which will then pick it up.
Otherwise you will have to allocate an IP address on the router, and then set the phone to the same address. If they don't match it won't work
It's a lot easier to let DHCP do all the donkey work. In most public areas DHCP is used as it is a 'Start it and forget it' system.
I set dhcp off because i assign an ip adress to every pc manualy and even have an mac filter where again the ip is written. I set the same ip on the phone as i had written it in the router config.
I can't acces even public wireless spots. I have the problem that it says the connection is available and then it says connecting and instead of connected it says avaialble.

IP address changer

Hi,
Could you send me link where I can download
App which can change IP address if exist?
Thanks
if you need to change the adress of your Wifi connection, simply go to your wifi settings, do a long press on the network and select "edit". Here you can change the IP Adress.
No, I need to configure manualy IP address because WIFI AP doesnt give IP addresses and I am not administrator of this AP and its company wifi.
Exist this program ?
you should be able to connect to the Wifi AP. Once done, it should either provide you with an IP via DHCP, or if this is indeed disabled as you say a zeroconf ip. If it's DHCP you don't seem to be able to modify the IP, but for zeroconf:
select the wifi network in your wifi setting, press and hold it, select "edit". Right under "proxy on/off" you should be able to edit your IP Adress, subnet mask and gateway adress as well as your DNS Servers.

Your advice it's nice bul****. If you are connected to wifi
you can allow only proxy server if you edit selected
wifi network and nothing else.
I ment program which allows me change ip address before
I log to wifi network.
I hope thats clear.

Why you want to change the ip of your phone to a static one for all networks yoy log in...
When your phone finds the network you want to log in connect to the net providing the password ... then after connecting and not haviing an ip address, keep the name of the network pressed with your finger and there you can change the ip address..
Did you try this yourself?

Did you try this yourself, and it worked? If yes, I wonder big time because that's exactly what did not work for me and my HTC Radar at my home Wifi network: Without a DHCP server running on the Access Point (no need for, only static IP addresses in use) the phone did not connect, just hang for a minute or so and then timed out. Only after I activated a DHCP server to dish out an IP to the phone it connected.

suppose(and this case is real in my case and applies to me..) u r not the admin of wifi router(u r nt connection owner) and u r in ur school and u want to connect to school wifi..but the router connects to only a limited set of ips..network admin has disabled dhcp server as in my ase..without preconfiguring the ip address before connection, u cant connect to ap..thats tragedy..dont think, oh i have never undergone such circumstances and ur network admin is a jack***..i know but i am helpless in this situation..all my classmates and my seniors are android device owners..so network admin doesn't change all settings just for helping a single person(at least in india..they ll ask u to use internet through library computers like dumbasses..)
THIS SUBSTANTIATES THE NECESSITY OF A FEATURE WHICH ALLOWS U TO SET A STATIC IP BEFORE LOGGING INTO ACCESS POINT..
also this feature helps to prevent all the little more work consuming process of logging into router, assigning static ip to ur device, and getting the static ip on device from router itself(but still thats DHCP only)..
Try Hotspot Switch IP. Is a free android app which allows you to change IP automatically by timer, remotely via web server, and also you can do it in app. Link: https://play.google.com/store/apps/details?id=hotspot.wifi.change.ip&pli=1

[Q] wifi is connected but no internet access

hello, I'm using an htc inspire 4g. I connect to wifi but no internet access. other devices connect to the router. I tried resetting the phone and it still doesn't work. Can someone help me fix this???
here's the software information.

You should check the settings for the WiFi network. Make sure gateway is set to the address of the router, DNS server is set to the address provided by your ISP (unless your router is providing a DNS service), and select DHCP as the means to get an IP address, or specify a static address if desired.

could u break it a down a bit more. The netmask was empty so i eneterd the one you gave me. i also type in the IP address that came up under the wifi that I'm connect to. I entered the IP at the gateway address. It's still not working.

The IP address you enter for the gateway address needs to be the local address and not the Internet address. Your router has one address that it presents to other hosts on the Internet, and one that it presents locally to systems on your home network. The former is your public IP address, and it will be assigned by your ISP. If you google "whats my IP address" on a working system on your network, and click one of the links in the result, you'll see your public IP address displayed. This is NOT what you want to enter for gateway address in your network configuration on your HTC.
You need the private address of the router. It probably starts with 192.168, and 192.168.1.1 would be a good guess. You need to consult your router documentation to see what it is. Also note that it could have been changed through the web interface to the router, by whomever configured your router. To verify you have the correct private LAN address, type http://<some IP address> in your browser, and you should see a router configuration screen, probably prompting you for a password. If you can't figure out the LAN address, post the make and model of your wireless router, and we can tell you the default LAN address, or you could google for that info also.
What do you have selected for how the IP address is specified? I guess the precise wording varies from ROM to ROM, but you can either define your own (static) IP address or select to have the router's DHCP server assign an IP address. You should select the latter, as it's simpler to configure. Then you need to make sure you have the correct DNS address. You can probably set this to the router's LAN address, which will work if the router is configured to pass through DNS requests. If that doesn't work, your ISP should somewhere tell you what DNS addresses (prime and backup) you should be using. You could also look at the network config of a working system on your LAN, and copy those settings on your HTC.
When all these settings are made, see if there is a selection to renew the DHCP lease, and do that if you find it. If you don't have that option, and it's still not working, select to "forget" the network, then connect to it again and enter all the settings from scratch and submit it.
Since you're connected to WiFi, it sounds like you have the correct password and security type set. The fact that you're connected to WiFi and not Internet suggests something is wrong with your IP configuration. Hopefully one of the things mentioned above will get you going.
It worked... Thank you

A weird restriction to access internet from wifi

Ask Question
I had a small quarrel with my stepfather, and then he didn’t let me access the home internet. When I try to connect to our home wifi normally, it says "obtaining ip address" and loops for minutes until it says "failed to obtain ip address." But when I try to connect by setting static ip from my phone, it connects immediately but says " no internet." I assumed he might have blacklisted me, but I am unable to connect even my laptop and other phones. Suspecting that my stepfather had enabled whitelist or MAC filtering, I tried to spoof MAC address using kali linux, but I couldn't connect to the wifi with spoofed MAC. I need internet but my stepfather won't listen to me. Since he is not in home right now and won't return for a month, I don't have a connected device to access the setup page and see the settings of our Digicom ( DG-M342T) router. I am also unable to physically access the router but I have the password( Authentication type - WEP). How do I fix this? I would really appreciate your help.
You could download the router's management app and then view the connected devices list on your phone. Check your router's setup guide to see which app you need to download.

I can't access the setup page by typing 192.168.10.1 in the url or from other Router management apps on the play store. It says " Can't reach the page." I also checked the guide where it says to open admin page by typing 192.168.10.1 on the browser , but there is no mention of any management apps.

Thanks for your reply jwoegerbauer. As I mentioned earlier in my post, if I connect to wifi just by typing password, it loops "obtaining ip address" for long period, and therefore I have to set static ip address through the advance setting of wifi just to connect to it. My router's local ip address is 192.168.10.1 . I used to access the admin page before the restriction through this ip address. But now it says "Can't reach the page." The problem is about not being able to access internet and admin page after connecting to the router.
Clear your local DNS cache to make sure you have the recent version from your ISP for 192.168.10.1. For Windows machine, you can do this by going to Start > Command Prompt > Type ipconfig /flushdns and then hit Enter.
Assumed that router's IP really is 192.168.10.1 and it still doesn't work then maybe ISP is blocking it. You may try to use an alternate DNS service such as Cloudflare for example.
I flushed the dns in windows. Now I can connect to the wifi without setting statip ip (in windows), but I still can't access internet. If I try to open any website, it says "
Hmmm… can't reach this page" and then says "You are not connected." I installed cloudflare WARP in windows but it was no use , since it requires internet access to function.
These are the screenshots of my android to explain what exactly happens:
1. When I try to connect to wifi just by typing it's password (loops at "obtaining ip address")
2. Setting the static ip manually
3. Instantly connected after setting static ip
4. Connected but No internet
5. Can't access router setup page
Cloudflare Warp? Confused.
How to change DNS Server to Cloudflare is explained in detail here:

Well thanks for your help jwoegerbauer. Below is the screenshot of ipconfig command after flushing dns. It looks like I haven't been assigned an ip address, the subnet is different, and the gateway is blank. Do you have any idea what this means? What could be a valid ip adress to connect manually with static ip?

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.
