Lost on Ip conflict issue?

[493]

Okay here's the deal. I have a PC and laptop and I recently purchased the PC and a wireless adapter for the PC which works like ass. Gets terrible speeds and goes to limited or no connectivity. I go to try and bridge the laptop with the PC through the laptops wireless and I get smacked with the IP conflict. I tried ipconfig /release and ipconfig /renew to no avail. do i need to set a static IP for each computer or what other things do i need to try? I've also tried enabling internet connection sharing and not fooling with the bridge but then it says cannot enable sharing because the computer already has an IP address used for automatic IP address or something along those lines. I'm stumped.
I'm not exactly sure how to change ip's and stuff like that. I know how to access the router but not how to set static ip's to devices or how to change dynamics to stay in a certain pool

We do not have enough info so I will make some assumptions

1. You may have a mix of static and dynamic IP addresses on the LAN. This is very workable without conflict IF and ONLY IF the dynamic IP address pool does not include IP addresses (let's assume you are using the 192.168.1.0/24 subnet and you have the dynamic IP address pool set to assign IP addresses from 192.168.1.1 to 192.168.1.254 - this means that all IP addresses in the subnet can be used in the dynamic pool - and any static IP address must be in the same pool - causing conflict. The solution is to limit the pool; let's say you have a max of 20 devices needing IP addresses - set the pool for about 50 addresses and you have more than enough - I suggest something like 192.168.1.200 - 192.168.1.249 and set the lease life to 24 hours max. Now make sure no static IP addresses are in the 192.168.1.200 - 250 range - change them if they are.

2. There is more than one DHCP server on the LAN - and each assigns IP addresses in the same range. I have seen this with people using a second router as a wireless access point and with some devices that also have a DHCP server. Have only one router do this; if you have a second router as a wireless access point, disable its DHCP functionality; assign it a static IP address in the same subnet as primary router uses and make sure it is not in the pool for DHCP. Connect this router to primary router by cable from LAN (not WAN) port of secondary router to LAN port of primary router.

I assume that your home network is set up around a wireless router that connects to your ISP connection.

First, let me comment on the terrible performance/reliability of your PC's wireless adapter. For some reason some wireless adapters are not fully compatible with certain wireless routers. On my own home network, I have experienced this problem four times over the past few years as I have upgraded my router or introduced new computers on the network. In a couple of cases, installing new drivers for the wireless adapters has solved the problem. In the third case, changing the wireless adapter was the answer. The final occurrence was a problem between my old router and a wireless webcam. The router upgrade cleared this problem.

If you have a wireless router and both the laptop and the PC have working wireless adapters, then you should be able to network both computers to the router with both computers configured to get their addresses automatically from the router.

If you want to use Internet Connection Sharing, then normally you will have to make sure that the router is not using sub-net 192.168.0.0/24. This is because ICS normally uses this sub-net for its secondary network that is offered to other computers, which are sharing the Internet connection. If your router is on the 192.168.0.0/24 sub-net, this could explain the error message you are getting when you try to configure ICS. With ICS, the secondary network provided by the computer through its second network adapter should provide a DHCP service and a router function for devices connected to the second network.

I have used ICS with a wireless connection to my ISP router, and Ethernet connection to secondary computers. I have also done this the other way round with the Ethernet connection to the ISP router and wireless connection to secondary computers. In the latter case, I had to use an Ad-hoc wireless network to connect the secondary computers.

If you want to use static addresses, then you should make sure that your static addresses cannot conflict with the addresses that can be assigned by the router's DHCP service. This does not matter if you have no devices using automatic address allocation by DHCP and all devices have static addresses.

I hope you solve your problem.
