Manufacturer and model number of your modem? (we need to find out if it is end of life)
Check your signal levels. Is it hot where you live? If your levels are out of whack they can get worse as the temperature goes up. (I just went through this over the course of a few weeks. A tech visit last week resolved the signal level issues. And yes, as the day got hotter it got worse)
First check when you are online and connected. Take a screenshot of the levels and save it to your computer.
Also bookmark the page. The next time you lose connection open your browser, go to the page and once again screenshot what you see. Compare the two. Usually there will not be much difference.
To check the signal follow the directions here:
Also read the tips for troubleshooting on that page.
After you have done all that click the blue this thread link in the first paragraph. Follow the directions and post the requested information. One of the connection experts will advise you.
Here is my canned speech about the Comcast help forum:
I suggest you post in the Comcast Help Forums.
Those Forums are provided to Comcast customers, and are a great resource for vendor specific issues. There are Forums for computer issues, email issues, security, internet, cable tv, CDV, billing, and customer service.
Many times we, the users there, can provide answers tech support and customer service can't.
Click the link below. The forum landing page will open. Click Sign In. Log in with your Comcast user ID (the part before .net) and your password. You will next see a first time forum users page, asking you to choose a screen name for use in the Forums. Once you set that up, you'll be taken back to the landing page. PLEASE DO NOT USE YOUR COMCAST EMAIL NAME FOR YOUR FORUM USER NAME.
Before posting, take a moment to read the Posting Guidelines. The link is on the top right hand side of the page.
Then choose the appropriate board to post in. In your case it would be Basic Internet Connectivity And Modem Help
One thing to be aware of: By default you will be notified via email every time someone replies to a topic you have started or replied in. If you do not wish to receive the notifications you can disable them by clicking My Settings/Subscriptions & Bookmarks tab. Uncheck the box next to [b]Automatically subscribe me to topics I participate in. Scroll down and click [b]Save.
DO NOT USE THE UNSUBSCRIBE LINK IN THE REPLY NOTIFICATION EMAIL. Due to a quirk with Lithium, the forum provider, if you use the link it severs the connection between your forum user name and the email address you sign in with.
Result: your forum account no longer exists in the database and it tells you that you are banned.
(Once you get to the forum, save the page to your favorites/bookmarks. If you want to get to it from the Comcast home page, you have to jump through hoops to reach it)
