Why does rebooting network router greatly improves wired network speed?

200 views

My router is on appliance timer to shut off and turn back on at about 3 AM because long ago I found rebooting it keeps it running at optimal speed. I did a test: file transfer between 2 computers on my home network averaged 10mbit/sec before restarting and can reach 100 (both computer’s max speed) after restarting.

I tried Googling but they all refer to wifi even when I searched for wired network -wifi (I guess Google is sometimes stupid about understanding my search query)

My post will probably get removed as being too short or whatever.

But imagine a super awesome, never stopping robot made of circuits. It just does its job over and over,.round and round and it does it well. This is what some routers or wireless are like

Now imagine yourself, a sack of meet. You need to sleep 8 hours every night to refresh your brain. This is the other type of router that you have. Powering it off and on refreshes the memory and such.

I can assure you, that in a network of 10 access points and 150 humans, we don’t need to reboot or turn them off.

Without a lot more technical details, it’s likely that there are some bugs in the software that over time cause the poor performance. Turning the device off and on again, cause it to start over without whatever bad state of memory is.

Not enough information, but you need to define speed. The router also has to keep track of the NAT table, Network Address Translation, which helps it know whats the best path to the next connection on the ISP, etc. A lot of ISP issued modems/routers are on the cheaper side and may not have much capacity so the NAT table can fill up and this can cause slowdown in general for the initial access of sites. Like first time you load reddit for the day is slow, but then the rest of the usage is usually fine.

10 mbps sounds like a suspiciously round number to me, and it’s exactly equal to the oldest Ethernet standard compatible with modern hardware. So my hypothesis is the connection starts out at 100mbps, then it changes to 10mbps in response to noise. I suspect it’s most likely an issue with the cables:

– How long are the cables?
– Are the cables over 20 years old? You need CAT-5 or CAT-6 cables, and these cables weren’t everywhere until 2000-2005 or so.
– Are the cables damaged in any way?
– Are there any major sources of electronic noise nearby?

(It’s not outside the realm of possibility that it could be a different problem, e.g. one machine’s network hardware, the router itself, or even a software problem. But I’d check the cables first.)
