Harpreet 11:45 AM I can do some troubleshooting for you internet
Harpreet 11:46 AM I would need to send a refresh signal to reactivate your
modem to resynchronize your modem to our system. Please allow me a minute
or 2 to complete the process.
Denis 11:47 AM Please do not do that.
Harpreet 11:47 AM Sure
Denis 11:47 AM Trouble shooting is not required.
Denis 11:47 AM Can you answer my question?
Denis 11:48 AM What does resynchronize mean?

Harpreet 11:49 AM Let me flush your DNS

Denis 11:50 AM So one answer to my question is Yes, the Arris TG1268T does
have a DNS cache?
Harpreet 11:50 AM yes
Denis 11:51 AM Good to know. Now, for future reference, is flushing the
cache something I can do, or must I contact Comcast to do that?
Harpreet 11:52 AM Denis, you can do it your self
Denis 11:52 AM Wonderful!

Harpreet 12:00 PM Please follow the link
Denis 12:03 PM OK. This appears to have instructions for flushing the cache
in my computer, not in the modem. Is this correct? If so, we get back to
the question of is there a DNS cache in the modem?
Harpreet 12:06 PM Denis, if you want to flush your Modem's DNS I would
request you please directly connect your device to the modem equipment
using an Ethernet Cord
Harpreet 12:07 PM Just for the confirmation, there is not DNS in the modem
Harpreet 12:07 PM this is a part of system
Harpreet 12:08 PM it is Domain Name Server
Denis 12:10 PM OK. I know what DNS stands for. Local systems often maintain
a local cache of recently used sites. My original question was does my
modem have such a cache. Now is seems your answer is No, it does not. Do I
understand you correctly?
Harpreet 12:11 PM yes, you are
Harpreet 12:14 PM Denis, I just wanted to clear you with the full of
details about the DNS
Harpreet 12:14 PM that is why it took time
Denis 12:15 PM Thank you for the education.
Harpreet 12:15 PM You are most welcome
Harpreet 12:16 PM I hope we have resolved all of your concern to your
satisfaction today?
Denis 12:16 PM I hope so.
