DNS requests timing out

My modem is connected (have rebooted many times today), WiFi signal is strong (also have used eth).   My issue is that DNS requests are timing out.  

This is my tracert. 

Tracing route to cdns01.comcast.net [75.75.75.75]
over a maximum of 30 hops:

  1     *        *        *     Request timed out.
  2     *     1877 ms     *     10.61.175.2

Timeouts and high RTTs in the first few hops of a trace usually mean there is a problem right from the get-go. Network connection problems that affect both Ethernet and Wifi devices are often due to poor coax connections or damaged coax cable, usually in or near your home. Running the cable through a surge protector, a defective splitter, or too many splitters can cause signal problems as well. If there is an amplifier in the line make sure it's getting power. 

If you want to troubleshoot this yourself, please see Internet Troubleshooting Tips. If you still need help, please post your Internet plan speed and the following information from your modem or gateway (from http://192.168.100.1 or http://10.0.0.1):

  • model number
  • uptime
  • downstream: power levels, SNR (or MER), and error counts for all channels
  • upstream: power levels for all channels
  • complete event log, if available (Be sure to remove or blot out any MAC addresses. Forum security processing considers them "personal information" and may prevent the event log from posting if these are present.)

Copy and pasted text is preferred over images. Be aware that, if you post any images, your message will be made Private for a time, as all images must be approved by the Forum Moderators before the messages containing them become generally visible.

If you can't find the problem or you'd rather have Comcast take care of it and an employee does not respond to your message here, call them at the phone number on your bill or 1-800-Comcast, or use one of the options on https://www.xfinity.com/support/contact-us/. It's not likely they can fix the problem remotely. If not, insist they send a tech out to identify the cause and correct it.

If the tech finds bad coax, splitters, amplifiers, or connections in your home (even if Comcast originally supplied them) you'll probably have to pay for the visit (approx $100) unless you have their Service Protection Plan ( https://www.xfinity.com/support/articles/service-protection-plan, closed to customers that don't already have it). If the trouble is due to a faulty Comcast rental device or anything outside your home you shouldn't be charged.

I have the same problem. Stong internet connection but "request timed out" several time in a row for 30 sec every 10-20 minutes. Makes Zoom calls impossible.
