Hi. I am on Gen4 using an HT1100 modem and for the last 3 or 4 days I have been experiencing intermittent connections and I will temporarily lose all internet connectivity. In the modem control center the status light will either be green or yellow and the connectivity test will say that I have limited access to the gateway during the time that it is down. If I reboot the modem, it will usually fix the problem for a while but sometimes after only a few minutes it's down again. When it is working I have used the testmy.net speed test site several times and my download speeds are excellent, but my upload speeds are erratic. Sometimes the upload speed is 1.5mbps and other times it will be 20kbps or less. I have tried the usual checklist. I have bypassed my router and connected the cable directly from the modem to the computer. I have also tried a different ethernet cable but it made no difference. All the modem lights are on. My signal strength is 98, which is pretty good for where I live. Thanks for any ideas you might have.
