Firstly, I own an Asus RT-AC5300 router running DD-WRT v3.0-r48362 std (02/15/22).

I am having an issue where I am randomly unable to reach anything on the Internet. After a reboot of the router, this issue is fixed.

I briefly tried to debug the issue using traceroute.

Here is the output when I am unable to reach things where IP is the WAN IP displayed in the dd-wrt interface:

Code:

root@DD-WRT:~# traceroute 1.1.1.1
traceroute to 1.1.1.1 (1.1.1.1), 30 hops max, 38 byte packets
 1  IP (IP)  1240.736 ms !H  1000.625 ms !H  2999.497 ms !H


Then, after a reboot, the output is shown as this:
Code:

root@DD-WRT:~# traceroute 1.1.1.1
traceroute to 1.1.1.1 (1.1.1.1), 30 hops max, 38 byte packets
 1  96.120.69.33 (96.120.69.33)  8.682 ms  10.202 ms  17.511 ms
 2  96.108.57.49 (96.108.57.49)  12.417 ms  8.448 ms  17.594 ms
 3  162.151.113.73 (162.151.113.73)  11.557 ms  14.029 ms  13.294 ms
 4  76.96.121.242 (76.96.121.242)  13.355 ms  21.787 ms  12.567 ms
 5  one.one.one.one (1.1.1.1)  14.646 ms  23.677 ms  11.116 ms


I am not great with networking so I am hoping someone has had a similar issue or may know what is going wrong.

Thanks in advance.

Hello, thanks for the report.

You are running an outdated and unsupported build, so any issues you are reporting are invalid until you are running the latest build and see if the issues are gone or still present.

DD-WRT is constantly being improved, patched and updated with newer drivers, kernels, libraries and components, all of these either fix bugs, patch known security vulnerabilities, so older firmware's are no longer relevant, unless they can be shown to be faulty.

See the latest builds under 2022 http://ftp.dd-wrt.com/dd-wrtv2/downloads/betas/2022/

Currently 05-23-2022-r48954 is the latest build supported.

Are you still using "Auto" in Wireless->Basic Settings->wl0->Wireless Channel?

Try changing the wireless channel? Just pick a different one.

Not sure if you were talking about the wired WAN connection... Smile

Hes talking about the internet connection being lost, so WAN, quite clear from the post and wan fixes went into dd-wrt after the build hes currently using, so anything else is moot without upgrade, reset to defaults and reconfigure from scratch.

I've had a lot of random internet drops. I was seeing it with my Streaming devices and with wifi enabled phone use. I fixed mine by setting the SFE to SFE (not CTF)...and changing the Flow Acceleration to Disable.

All my drops went away.
