Hi, command to release and renew ip addresses should be
although if IP addressing is causing a problem, assuming each device is correctly receiving a dynamic address then could hostnames be used?
sorry, you lost me. keep it simple cos i'm thick. ip addresses have been assigned by system after broadband issue. but main pc ip address has been changed from 192.168.1.66 to 192.168.1.64.
problem is Synergy uses IP addresses to communicate, so I want to change the new Ip addresses back to before. It was simple last time. but cannot remember teh cammand and syntax
ok - checking....
Just to confirm - is each device on the network set to obtain an IP address automatically?
Lost me again. How can I tell? is it DHCP? have gone into daignostics of my BT router. DCHP is set. it now has given my PC's IP to my phone and my laptop's ip to my printer. I think that it forgets from time to time which is what, reassigns IPs and then starts all over again. For example, it has just given my laptop the IP for my Apple Mac, so now that's buggered. I have a lis tof all the IPs as they were and that's how I would like them to stay, seems simpler to me. Can I do it? Is it a good idea. What happens if IPs are fixed and I take my Ipad ( say) to an internet cafe where it clashes with someone else's?
Yes - that sounds like DHCP, the system maintains a 'pool' of addresses and they are allocated on a first come, first served basis so they can change from time to time. The way to prevent this would be to either program each machine with a static/fixed IP address although this would then run into issues like you say when the iPad is taken to an Internet cafe.
The best solution would need to be to set the BT router to reserve IP addresses for your equipment based on their unique information. So the PC would always be allocated a certain address as would the iPad etc
but this wouldn't effect taking the iPad to other sites and using it there
The quickest way to resolve this would be to remotely connect to the router and make the changes. Unfortunately I can't do this as only certain experts have the Just Answer remote access tools and I'm not allowed to use my normal tools here
I can opt out for another Expert who could remote in? They will see the chat history so far as well
Let me know
rather stick with you if we can. Have accessed router and looked at DHCP table. On each device there is option to "always use this IP address". Have set this to Yes for devices with correct IP address. Then plan release the other devices from their own command prompt and renew until they come up with the addesses I want. BUT, can't get the syntax right for ipconfig /release. command ipconfig/release brings up "the requested operation requires elevation" (should I try standing on a chair?)
ah - the old elevation message
if on Windows 7 or Vista you have to run the Command Prompt as an Administrator
If you go to Start-->All Programs-->Accessories
and right-click Command Prompt, then choose 'Run as Administrator'
that should then allow the IPconfig commands to function
gotcha. but it reassigned the same IP .. presumably it assigns the lowest available, so I need to take them offline in order so that the number is XXXXX or do I have to switch oof the router each time?
taking them offline in the order should be sufficient
will have to go now. start again tomorrow.
OK, the deal is done. Tx for the heads up on how to make IPCONFIG work. Working from the router, lock all IPs that match my schedule. then shut down all devices, and that means power off, particulaarly with the phone. You have "give up the lease" on the IP addresses at the router. In my case, easiest to set lease time to minimum 1 hour and go and watch Telly. then bring up devices in sequence and as each is assigned an IP, lock it via the router software.
