Static IP address for a particular wireless router or hotspot?

[nigelmercier]

Is it possible to configure Windows 7 to have a static IP address for a particular wireless router or hotspot? I know I can make my wireless adaptor have a fixed IP, but that somewhat limits it!

Why exactly do you want that?
Do you have rights to change the settings on the router?

I don't want to change the router settings. I want to change my adaptor settings so when it connects to this AP (only) it keeps the same IP address.

You can set the dhcp-server (in router) to do the following:

• If your wireless network card asks for a dynamic tcp/ip address: Give as answer a fixed ip address.

Sure you don't want that? I ask because this is the normal way to do it.

Why do you want a static address? Has your computer some server functions?

I guess, "because I do!" isn't enough?

Some users on SevenForums are smart and a lot have almost no computer knowledge at all. I respect you don't want to tell me the reason.

To answer you initial question.... it's possible but not with a few clicks afaik.

I don't mind telling you, it's just complicated. A cafe I visit regularly with my laptop has free Wi-Fi. Sometimes I can't get access, and I wonder if they have limited the range of the DCHP server to just a few addresses; I've noticed recently that the last digit of my IP is in the range 50-59. They have about ten tables, so I guess this makes sense, but the server won't release the old IP addresses until their lease expires, I think two hours.

I figured if I could have a static IP for this location, outside the DCHP range, then it would fix it. I could try talking to them, but they are Spanish, and this would be out of my vocabulary.

You can connect wirelessly...but no ip address? Try to set ip address manually. dhcp starts from 50 at least it looks like that. So put another number for example 40 after the last dot. Works?

That was my original question, how to do this for this network.

I do hope I'm not interrupting anything... Just wanted to ask, what was the subnet mask? This gives an indication of the potential ranges of IP addresses that we can potentially play with. Before you can really set any static IP address you need to have a valid DHCP given one or at least know the router based settings.

I think I've cracked it. Under the IP4 settings for the adaptor there is a second page to enter alternative settings, I've put the static IP in here. When the original settings fail, it should fall over to these.

Don't know why I didn't think of this before, I knew it was there!

But then it works like:

1. Try to get a free ip address using dhcp... if failure then
2. static ip address you defined yourself. (including subnet, default gateway, dns server)

Now it assigns the same static ip address anytime dhcp fails (over wireless adapter). So not only in the WIFI-cafe

I hate to intrude, but I strongly suggest that you talk to the people at this cafe you refer to. Network settings like DHCP are configured in certain ways for a reason, and the management at the cafe might not like you using static IP addresses to connect to their network without their prior knowledge.

There is also a very legitmate risk of IP address collisions since you are not 100% aware of how DHCP is setup on their cafe network and how IP addresses are allocated. If you inadvertantly knock a piece of cafe hardware or another customer's laptop off the network you'd be responsible for it.
