On Windows 7 you go into the network and sharing center and then on the right hand side there is a connection: (XXXXX). Click on that and then go to properties. Find Internet Protocol Version 4 and click on properties again. Change your DNS server there by selecting Use the following DNS server.
google primary 8.8.8.8
google secondary 8.8.4.4
You can also set up static IP addresses here, although I wouldn't mess with it if you don't know what you're doing. If you want to set them up it is easy to explain though.
If you want to set it up for all the computers at once type your default gateway IP address into a web browser and log in (typically admin/admin or admin no password). The first page that comes up should have DNS static 1, 2, 3 which you'll change to the above. Leave 3 blank or grab the primary DNS you're currently using. To get your default gateway and DNS servers type ipconfig /all into command line (typically 192.168.1.1).

In your router, there should be DNS settings. You want to set it to static and set primary to 8.8.8.8 and secondary to 8.8.4.4. You can also do it locally for each computer as Blitzkrieg0 pointed out.
Yes it's dynamic by default

I googled to search if my connection was static or dynamic ; it says if with ipconfig /all, I find dhcp "no" then it means static. Assuming my internet is indeed static, does it conflict with router default settings? Its the first time I'm having this issue with any router

The DHCP server assigns IP addresses to computers and has nothing to do with DNS. Your router is probably your DHCP server and your DNS server should be through your ISP. You may be having IP conflicts if some of your computers have static IPs and the DHCP server is assigning those addresses to other computers.
Make sure all your computers are set to automatically be assigned an IP address (or make a unique static for each device; I can walk you through how to set that up if you want). You'll also want to make sure your router has DHCP enabled, but it should be on by default. You can check by typing your default gateway into the web browser and logging in. DHCP Server enabled or disabled has little bubbles about halfway down the page.

I'm pretty sure all computers are set on Auto assign IP, ill verify right away.
Changing the DNS to the google, do you think its enough to fix my problem? I can't do it right away since my brother needs the internet for a while (so I can't disrupt it)

It sounds like you're having an IP address conflict which requires other measures, but you can try using Google's DNS servers to see if it fixes your issue. If one computer works and the other doesn't then there shouldn't be anything wrong with the DNS server (You could also do an ipconfig /all and verify that they're using the same DNS servers, but that shouldn't be the issue).

You can set the DNS server that's used on the PC. You don't need to touch the router for that.
Through DHCP, your PC gets its IP and also the DNS server to use. You can override only the DNS part without disabling the automatic IP. It looks like this in practice: http://i.imgur.com/dudWykm.png. Here's IPv6: http://i.imgur.com/67vM9ie.png. Those are the Google DNS servers.

Oops, I went ahead and changed my router settings to use the DNS of Google
If the DNS isn't the issue, what can I do to fix my IP conflict issue (or how can I verify that it is an IP issue?)?

Basically my idea is that some device got locked into static when you tried to configure it that way. Your router assigns that static IP to another device because it is on dynamic and then you have an ip address conflict and one of the devices doesn't work. It claims a DNS issue because the DNS server it tries to contact is routing all it's traffic back to the other device because the routing table in the router has the other device as that IP address so it doesn't send anything to the second device with the same IP address. When you do a hard restart of the router that IP address would be flagged in use because it was leased recently and then everything is assigned a unique IP address and works just fine.
Your DNS server shouldn't be broken when it is working on a computer but not on another. Since this problem has been occurring across multiple routers then your problem should be the one listed above and not related to the router itself at all.

Go into the network dialog on the PC itself from above and verify that all of them are obtaining IP address automatically. That will make them pull from the DNS server. Alternately you can go in and setup a static IP address on all of them which I can walk you through. If two of your devices start acting up again you can do an ipconfig on them both and verify that they each have unique IP address. The last octet of the IP address should be unique (192.168.1.X). The X number at the end is the last octet of the IP address. If your first three octets are different from the ones I listed above that doesn't matter.

Ok, I got control of all my PC now. So if I understand well, if two PC's IP conflict, it will crash the entire network? Because sometimes, I can't connect to the internet on more than 2 computers. Most of the times though, its a conflict between my wired devices and my wireless. Wired doesn't work, but wireless does

It claims a DNS issue because the DNS server it tries to contact is routing all it's traffic back to the other device because the routing table in the router has the other device as that IP address so it doesn't send anything to the second device with the same IP address. When you do a hard restart of the router that IP address would be flagged in use because it was leased recently and then everything is assigned a unique IP address and works just fine. Your DNS server shouldn't be broken when it is working on a computer but not on another. Since this problem has been occurring across multiple routers then your problem should be the one listed above and not related to the router itself at all. On July 29 2013 08:07 XenOmega wrote:

If the DNS isn't the issue, what can I do to fix my IP conflict issue (or how can I verify that it is an IP issue?)?

I am going to suggest you setup static IP addresses on everything just because it is the easiest way to verify if this is your issue or not.
First you need to go into your router and check which IP address your DHCP server is dynamically assigning. After opening your default gateway in a web browser it should be about halfway down the page. My DHCP server starts at 192.168.1.100 so I'll be utilizing it in my example. You can change yours to match + Show Spoiler [just in case] +I have assumed that you're using the standard public class C address for your network in this example. If your network isn't using 192.168.1.X scheme then copy whatever your first three octets are and follow the same principles.
Then simply keep increasing the last octet by one for each new device so I have my second PC set to 192.168.1.3 and my network printer set to 192.168.1.4; you will have to go in and manually configure this IP address on every device on your network. Make sure your DHCP server is starting at a different number so that it doesn't make a conflict with an IP address that you've assigned to a device.

Assuming my internet is indeed static, does it conflict with router default settings? Its the first time I'm having this issue with any router The DHCP server assigns IP addresses to computers and has nothing to do with DNS. Your router is probably your DHCP server and your DNS server should be through your ISP. You may be having IP conflicts if some of your computers have static IPs and the DHCP server is assigning those addresses to other computers. Make sure all your computers are set to automatically be assigned an IP address (or make a unique static for each device; I can walk you through how to set that up if you want). You'll also want to make sure your router has DHCP enabled, but it should be on by default. You can check by typing your default gateway into the web browser and logging in. DHCP Server enabled or disabled has little bubbles about halfway down the page. I'm pretty sure all computers are set on Auto assign IP, ill verify right away. Changing the DNS to the google, do you think its enough to fix my problem? I can't do it right away since my brother needs the internet for a while (so I can't disrupt it) It sounds like you're having an IP address conflict which requires other measures, but you can try using Google's DNS servers to see if it fixes your issue. If one computer works and the other doesn't then there shouldn't be anything wrong with the DNS server (You could also do an ipconfig /all and verify that they're using the same DNS servers, but that shouldn't be the issue). But the Router is supposed to assign automatically right? I was with an old router (dlink) for a few years (Dlink dir 615? not sure) and never had this issue. It started with Mynet central 900 from WD, and it continued with Asus 56. In my post earlier, I said I believed it could be due to me trying to switch my ip from dynamic to static, and vice-versa. Otherwise, if that's not the cause, then the only thing I can think of that changed was me switching router Basically my idea is that some device got locked into static when you tried to configure it that way.

If your network isn't using 192.168.1.X scheme then copy whatever your first three octets are and follow the same principles. or just follow the principles so that nothing conflicts The first three octets of the IP address which are in bold ( 192.168.1.X) should be the same for your entire network. You'll copy these throughout. The last octet must be unique for each device so you'll be changing that X value so that each device in your network has a unique IP address allocated to it. The network address should be .0 and your default gateway should be .1 so we're going to skip these. My first device is going to be assigned the next IP address so it will be 192.168.1.2 Your subnet mask should automatically fill in at 255.255.255.0 which is correct because we aren't doing any subnetting. If it doesn't autofill simply put in 255.255.255.0 as well. Your router (default gateway) is 192.168.1.1 so fill that in as well. If you have laptops, phones, or other devices that are used in multiple locations then you'll want them to be dynamically assigned IP addresses because your static IP address won't work with any network you pick up. There is a way to setup multiple schemes, but it is beyond the scope of your problem I believe so we'll worry about that down the road if it is an issue.

I'll give this a try tomorrow
I had a weird issue after chaning to google DNS. Everything was fine, until I opened everything. At some point, all computers lost connection to the internet (in the network, the internet was not connected in the graph). Resetting modem didn't change a thing. However, as soon as I finished transfering a big file, I regained internet O.o (during the downtime, I was not able to access the router neither with the 192.168.1.1 url)

Nevermind, already was answered.

update on my situation : Have not set up the Static ip yet
I was checking my CLIENTS tab, and decided to refresh it...
Lost partial connection. League of Legends + Skype were still working fine, everything else was not accessible
Refreshed again : All connections work now.
|
I've upgraded the firmware, hopefully, this will fix the issue!
About the QOS, is it supposed to work? I have it on, but my network seems to be unable to handle the traffic from HD streaming, gaming, internet, downloads, etc.
|
QoS just attempts to prioritize certain traffic over others. If you don't have the bandwidth, it won't help.
