DNS problem |
|
|
Hi,
I am having a strange problem with Linksys WRT54G router. Every couple
of days, I start to experience problem accessing web pages. The DNS
servers are not responding when I try to ping them. However, if I
restart the router, the problem goes away. I have a Link RTP300 (for
vonage) behind the WRT54G router. WRT54G is connected to the cable
modem.
I have contacted Linksys tech support but they were of no help. Anyone
with this problem? any suggestion?
thank you. |

My bet is somewhere along the way you made some seemingly innocent change to
the router's settings based on incomplete information about what the impact
of the change would be. Perhaps you read somewhere that this or that should
be enabled or disabled because it provides more security, but it wasn't
fully explained why it provides more security, and actually had other
unintended results.
Reset the router to factory specs, and set it up from scratch again. Pay
close attention to any changes you make in the configuration, and what
impact they have. If you're not sure of what the full impact is of any
changes you make from the factory settings, don't make the change until you
research it. Don't make any changes based on blind-faith; know what the
change does.

There is a problem it looks like when the router is renewing it's IP,
the DNS is either not updating or is updating to all 0's. I've had this
problem before. You can verify this by waiting until the problem
happens, then checking the status page of the router to see what the
router has for DNS. Run an ipconfig/all to match the DNS servers on
your computer to what linksys has. They should all match.
If you can't ping your ISP's DNS, maybe their public DNS servers are on
DHCP addresses themselves. That would mean that when you obtain an
especially long lease from your ISP's DNS server and during that lease
the address of the DNS server(s) change, and a new DHCP update is not
set, it would explain the problem. Verify the IPs of the DNS servers
over some time.
If all else fails, maybe your ISP simply has flakey DNS servers and you
should consider using some others -- there are public ones (but don't
use the root). I run my own DNS server and this reduces browsing time. |
