My DNS Lookup & Initial Connections are very slow. Here is what I did: (Using Fedora Linux)
Install OpenWRT on my new router
Connect its WAN port to my ISP's router's LAN1 port
Connect my PC to the new router's LAN1 port
Changed password and disabled SSH in Luci
The problem begins here:
5) I look up some things on the chromium browser
This is very slow
PFA:
Monitoring with network page of dev ops in chromium shows the following for the "document" that is requested when a url is entered in bar or clicked in search engine (ignoring the ads and tracking links by the search engine, I am talking about here the "document" for getting the page such as "/page-index")
setting DNS manually in my network manager and browser to 1.1.1.1
setting DNS forward in luci to 1.1.1.1 as well and increasing DNS cache to max (10000)
rebooting several times
Why I think it is an OpenWRT issue:
keeping everything the same, if I now connect to a VPN wireguard config file in my net manager while staying on OpenWRT router fixes the problem
removing the OpenWRT router from the path, i.e. connecting the cable coming in to new router's WAN port from the LAN1 of ISP router now directly to the PC gives no such issues
Please help, any assistance is deeply appreciated!
Thank you!
I am talking about the time taken for the initial connection as seen in the screenshots I shared above. (The screenshots are from inspect element > Network > the page request document)
What subnet is the ISP router using, compared to the OpenWrt router? You’ve added an extra hop to get the return traffic delivered to your clients. Does your ISP play any games to manipulate TTL on packets? Probably not, if they are just slow, but this isn’t going to be a DNS issue if subsequent IP connections are also slow.
