Better Power Supply for a Router?

I work in the networking industry (Cisco 17 years, Broadcom 3 years), it is ALL snake oil.  The power supply it came with is adequate.

@cakyol, it's good to hear from an industry expert.  What are your thoughts on the quality of ethernet cable running from router to streamer... and what about the quality of the router?   I'm using a simple Google Nest router with stock cable into my Bluesound 2 Vault streaming Qobuz.  Should I stick with what I have or can sound quality benefit from an upgraded router and upgraded Cat 7 cable?

Here is a good table that gives all the typical cable limits (towards the end of the page):

I am not exactly sure what "stock cable" for your router is, but my guess is most of these devices will operate with cat6k cable without any issues. But hey, these days cat7 cables are almost the same price as cat6k cables, so there is no harm in upgrading for future proofing your installation. You do NOT have to spend any excessive amounts of money for ’audiophile’ ethernet cables. There are no such things except money traps. As long as the cable you already have are within the specified specs, you will have no problems.

If you are experiencing any problems, typically your cable modem (connection to the service provider) is likely to be the bottleneck than either your own home router or the wiring, especially when too many people start using the internet simultaneously.

I am really happy to say that, It is a very interesting post to read. I learnt new information from your article, you are doing a great job mycfavisit! Thank you.

@cakyol, thanks for sharing your knowledge!
