DHCP issue, HELP JC!

19/07/14(Sat)15:12

Yesterday I noticed I couldn't get online. A small yellow !-mark was in my internet access icon.
I tried enable/disabled of the network adapter: nothing.
Reset the modem/router: nothing.
Restart the computer: success, except that the next day it started all over again.
Checked the wireless route: smartphone could connect to the internet.
Checked on the same computer with a wireless card if I could connect: yep, no problem there (wireless adapter uses standard automatic ip address)

So I changed the ip-address from static to automatic: success!
It gave me .67 as last ip number.
I checked the modem/router settings (see pic) and it has 'Lease duration: Permanent duration' ticked-on. So I was wondering if that would be the issue?

>>28528 you may find that your router provides for static addresses by simply allowing you to allocate 'static' addresses to your devices but using an ip address that is outside the allowed dhcp range.
So if DHCP range is 65 to 254 then you could give a device a static address below 65, but you will have to check that your devices all have unique addresses.

You should be able to use the permanent allocation to get a static address if your router doesn't have any option to reserve an allocated address.

I need to check if my router allows it. nope, can't find it. I just did a restart and also turned off the router, I'm back online again. Weird MS BS?

Static addresses can be a problem sometimes when they are set on both ends of the connection. I found a while back to set the static address for each device on my router and let the computers get that address automatically from the router. Of course not all routers allow for this.
Permanent allocation shouldn't be a problem.
DHCP should be on or you may not be talking to the router on the approved IP address.

If all else fails delete the network adapter in hardware manager and then scan for new hardware and go with default settings.

Btw, I changed my ip-address back to .65 and, as you can see I'm online. Wireless adpater has been disabled, btw.

It does show in the Network Details that DHCP is off??
