You should really try changing you DNS server to some faster ones. I was |
| 28 |
having this same problem with my ISP or DSL modem with built in router |
| 29 |
taking a long time. I changed my DNS servers to Google DNS Servers |
| 30 |
(8.8.4.4 and 8.8.8.8) and haven't had a problem. |
| 31 |
|
| 32 |
My setup is a little different but all in all I would really suggest you |
| 33 |
try a DNS server outside of your ISP. |
