Hello:
I'm using JDownloader on W7. My internet connection is by menas of a coaxial cable connected directly to a Scientific Atlanta modem and from this to my machines by a network cable. The service is provided by my cable company.
I was using the following commands inside a batch file as an externar reconnector:

ipconfig/release
netsh interface IP set address "local" static 1.2.3.4 255.0.0.0 1.2.3.5 0
netsh interface IP set address "local" dhcp
ipconfig/renew

Where "local" is the name of the network connection in windows.

This commands were working perfectly on Windos XP but, although the script runs fine, showing no error messages on W7, the ip adress remains the same.

I have read it is possible to change de MAC adress of the network device but with this method it is necessary to turn the modem off and back on, which is unpractical and totally against the spirit of automatization.

Believe me, I have tried different variations of the latter sequence, including netsh commands with no better results. All that is left is to get into studying tcp/ip or hope some of you can help... please?

I think Windows 7 recognizes that you are attempting to set a static IP address that is illegal. As part of its security improvements, it ignores requests for a few seconds.

I would like you to try using 10.2.3.4 instead of 1.2.3.4. You might even try a real, but unused IP address. Use Google to search for bogons (bogus IP values, often used to try and break security). Since you are not doing any I/O during the time this is active, it doesn't matter.

Make sure you have not blocked the IP address you choose in your firewall.
You also might want to change your IP Mask for the static address to "255.255.255.000".

You only have to change the MAC address if your ISP issues a "Sticky" IP address. That means that restarting your modem does not change your IP. This is obviously not the case, since ipconfig /release, force network change, ipconfig /renew worked in XP.

Ok. Tried 10.2.3.4 with the same results.
Changing from 255.0.0.0 to 255.255.255.000 gives an error message (translating from spanish would be: invalid mask parameter). So I stuck with the first.
Then tried some bogus ips like 203.0.113.0 and others like i show in the capture. No luck.



I'm starting to worry about this. I don't want to change mi ISP for some with a more dinamic IP policy. And I kind of like W7, and I'm aware XP will some day cease to be supported.

Please, any more help?

You are still using illegal IP addresses in your netsh static line. You have to combine into something like 181.1.1.1 255.0.0.0 181.1.1.254 255.0.0.0 (0 is illegal in addresses, gateway address should be in the same subnet and same mask as local address)

If that doesn't work, I recommend disabling the TCPIP6.sys and mstun.sys (tunneling) devices. You might have to deactivate matching services (these will show as errors in the event log) These are "hidden", so you have to enable View hidden devices. They will be in the non-PNP devices section of the device list. This will also simplify seeing what is happening.

You should put an IPCONFIG /all between the two netsh commands, so you can see what is happening.

I have had to disable these under XP, because they are subject to hacking (that causes bluescreen) in my version of the OS.

Thank you for answering:
I was able to modify the script to this:

ipconfig/release
netsh interface IP set address "local" static 181.1.1.1 255.0.0.0 1.2.3.5 0
IPCONFIG /all
netsh interface IP set address "local" dhcp
ipconfig/renew

With the same results.

I don't know how to disable those devices you mention. (I'm a technophylic but actually into art).
I unchecked TCP/IP v6 in my conection ("local") properties. But the same. Checked it again.
Can you tell me where to disable those, please? I can make my way with some guidance.
Looked into the event log, but I don't know wich category yoy refer. Nevertheless there's no red sign warning in any but one, video card related.

I leave you this capture with IPCONFIG/all executed after the first netsh



Thank you so much for your attention!

I don't want to interrupt this way above my head technical dialogue but, why do you use screen dumps and not simple text copies?

Simple, I don't know a better way to show the contents of a DOS windows. Dunno how to copy and paste frome there.
Like i said before: I'm technology-friendly but in fact into art, so some things may escape me.

How would an easier way be?

Can you think of a workaround to the reason of my post?

Thank you!

To copy text from the console, use the scroll bar to make the beginning of the interesting text visible. Then, right click on the window or text and select "Mark". Click on the beginning of what you want to copy, drag the mouse to the end of what you want to copy and lift the mouse. This copies a rectangle , so make sure you start at the top left and stop at the bottom right corner of the rectangle you want to copy.

Press Enter to actually copy. Ctrl+C cancels the copy, it is not a copy command here. The text you copied will be in the Clipboard, ready to paste when and where you want.

See http://board.jdownloader.org/showpos...5&postcount=49 for information about removing or disabling drivers and services (I was writing it for you, then generalized it a bit and put it into the general Windows repair thread).

In addition to the things I suggested removing in the repair thread, you might want to remove Teredo. Usually, that is installed by uTorrent to allow communication with computers where the ISP filters BT packets.

In your case, the reason to remove all IPv6 and tunneling protocols is that the IPv6 may be preventing your ISP from assigning you a new/different IPv4 address.

Alright, thank you very much. I could do some of the things you said in that thread. There were issues:

- Could not find MS Tunneling Protocol, NetBT or Browser in the connection properties. I did uncheck IPv6 and "file and printer sharing" and could disable NetBios over TCP

- Some services weren't listed: Browser, Cliphook (either it's not listes or I can't find a proper translation), Java QS, NMindexing..., Terminal Services. I disabled the ones I found.

- Once the pc restarted, i couldn' find any of the non-PnP drivers you mention. Here's a cap:



I could remove Teredo, though.

Ran the batch file, wich now looks like this:

ipconfig/release
netsh interface IP set address "local" static 181.1.1.1 255.0.0.0 1.2.3.5 0
IPCONFIG /all
netsh interface IP set address "local" dhcp
ipconfig/renew

But my IP stays the same...
Could any of your instructions I didn't manage to follow be affecting this?

Thank you for your kindness and dedication.

I do not have enough experience with the Windows 6 family (Vista and "7") to be sure of further advice. The netsh static should tell your computer to forget your last IP address. Instead, the ipconfig /renew is asking for the same IP address as you had before.

You can disable NETBT and I think you can disable Controlador ARP IPv6 de Access Remote (remember about saving a restore point).

Other drivers you can try are:
Any of the Compabilidad drivers (compatibility with Windows 5 family) and TCI/IP registry compatibility, but this will break some programs.

The QoS driver (Programador de paquetes QoS) is usually a waste of memory. It is there for telephone over TCP or Television over TCP. If you do not have those, you probably should disable that driver.

On my own machine, I could experiment if I were running Windows "7", but I do not think you should do that.
---------------------------
You can add IPCONFIG /flushdns right before the IPCONFIG /all. I do not know if this will help, but it cannot hurt.

Check your HOSTS file (it is usually in C:\Windows\system32\drivers\etc) to make sure that the only setting in there is "127.0.0.1 Localhost". If there are others that refer to your computer name or to Localhost, that could cause this problem.

You can try changing the IPCONFIG /RENEW to IPCONFIG /RENEW 0.0.0.0
Again, this cannot break anything, but I do not know if it will help. It is possible it will tell DHCP that you want address 0.0.0.0 and DHCP will know you cannot have that and ask for a new address.

You can use netsh dump (during normal running, not static) to get a list of all of your netsh settings (as a script for setting them the same later). Looking for your old IP address may tell us what you need to change. I would need it as text if you send it to me (use right-click, then Mark, not Print Screen). You could include it in a PM. Or you could examine it yourself.

I think the answer is in there.

drbits

Thank you drbits again.
Tried disabling those drivers you mention, but still the same.
ipconfig /renew 0.0.0.0 gives an error message, something like there's no adapter available

I executed netsh dump. I really don't know what to look for. I think we could make the best of it if you take a look. I sent it over PM to you.

Again and again, thank you for your help and kindness.

Have you changed ISPs in the meantime? I use Windows 7 at home and have tried that exact string of commands for the same use. Works just fine, using standard windows 7 network settings. I'm using a corporate Atlanta ISP, through an **External links are only visible to Support Staff**Atlanta Translation Services office LAN.
