I have very slow browsing even though I have a good connection to router. When I type a site in the browser you can see it struggling to resolve it. Using Gmail I get repeated messages from google saying Somethings wrong here and it stops while Google tries to reconnect. I am using DHCP so my PC's DNS is using the routers DNS which in this case is Orcon's dns servers. (121.98.0.1 & .2 Am I better sticking with Orcons DNS or using Googles or OpenDns or what

Any suggestions please

Depending on the router, you could get it to hand out your chosen DNS servers, rather than acting as a relay - this way if the router is a bottleneck for resolution, you will bypass it.

You don't say what ISP you are using, but it is generally better to use ISP specified DNS in order to properly resolve local CDNs.

Sorry My ISP is Orcpn which is why I am using their DNS. Its coded in the router.
I could just ignore that and plug in some other DNS in the netword card settings in Windows just wondering what is the best one to use. I see some lauding the virtues of OpenDNS and also others loving Googles.

Test the response time of each of the DNS servers used by your router.

From a command prompt, do something like:

nslookup
server 121.98.0.1
www.google.com
*** see how long this takes to respond ***
server 121.98.0.2
www.google.com
*** see how long this takes to respond ***

If you find one of the DNS server slow then don't sue it. If you find them both slow then try some other DNS servers.

I am also assuming you aren't relying on WiFi at the moment ... if so plug into an Ethernet cable and make sure the problem is the same.
