fair do's
can you contact GB to make them aware that the driver has an issue with netgears auto-negotiaton...appears to be after a set time like 3-4 hours I think, I think its something to do with DHCP and IP renew time or some stuff like that
ive found a fix...well early days but i applied it when it was broke (well slow to connect) and it connected instantly when i applied it and has done every boot since, i manually entered the routers, computers & subnet mask IP settings into IPv4 on the Local Area Connection. I got this Idea from a post of someone who had a different (but similar) problem with the same Realtek Gigabit LAN Chip, I also set 100Mbps Full DUplex in Advanced Adapter properties so it doesnt have to negotiate that but I dont think thats the problem but it was an extra step i took.
heres some of my post from my thread about it, i posted it for the other lad who has same problem on a Z68 board:
early days BUT think ive found a fix until GB sort it - this is manual workaround until Gigabyte release update
its the auto negotiation of IP address between Netgear Router and LAN chip that seems to be the issue, after a set period of time it starts to have problems with negotiation - Gigabyte must release an update to address this
so, heres what I done and I done it while it was broken (well, only connecting after 64 seconds)
I manually entered the network and computer IP address and subnet mask (I also added Open DNS as DNS server until I use DNS Benchmark to see which is best later)
netgear router ip is 192.168.0.1 and every computer connected after that the 1 is a 2 then 3 then 4 etc etc (PC1 = 192.168.02 , PC2 = 192.168.0.3 etc etc)
if you run into problems again do this: (assuming your netgear default gateway is 192.168.0.1 like most netgears)
you can find out by opening
RUN (Windows key + R) and typing
CMD and press enter, then in cmd window type
IPCONFIG /ALL (note there is a space between the IPCONFIG and /ALL) - this will display your network settings, SCROLL UP and look for default gateway under
'Ethernet Adapter Local Area Connection' (not Tunnel adapter lan) it will show all the other settings you will need to copy into below (in red) if its different to mine, but should be the same)
edit: get your ISPs DNS servers IP addresses too from the ipconfig list under 'dns servers' in case you run into same problem of being only able to change both IP & DNS or nothing at all as thats whats happening to me.
right-click on Network icon in tray and choose
"OPEN NETWORK & SHARING CENTER"click on the
LOCAL AREA CONNECTION link
click the
PROPERTIES button
double click on
INTERNET PROTOCOL VERSION 4check 'use the following IP address' and enter the following (no other PC's should be on network when you do this)
IP ADDRESS: 192.168.0.2
SUBNET MASK: 255.255.255.0 (this will probably fill itself)
DEFAULT GATEWAY: 192.168.0.1
Enter your ISP's DNS values into these boxes:
DNS SERVER 1: xxx.xxx.xxx.xxx (enter your ISP's DNS server 1 values here or use open DNS: 208.67.222.222)
DNS SERVER 2: xxx.xxx.xxx.xxx (enter your ISP's DNS server 2 values here or use open DNS: 208.67.220.220)
press OK, OK, CLOSE and it will re-connect... then reboot and see if it works... for me the shutdown hung, soon as i removed ethernet cable it shutdown...but shutdowns after that have been fine
here is a pic of what mine looks like with my personalized DNS Servers:
edit: I also changed the settings in advanced section of adapter properties 'speed & duplex' to 100Mbps (from AUTO) so it doesnt have to negotiate for that eithertry that and see if it stays fixed, this is actually better and quicker as it doesnt have to negotiate with the router, but none-the-less there is a problem and Gigabyte need to address that.
