    Swtiching over from Powerline to Moca 2.0 - New Setup Help

    worse than wifi. On 2.4Ghz wireless N, 30% of link speed is your practical speed. on 5Ghz wifi AC 50% of link speed is your practical speed. However when it comes to latency, a fast wifi setup is only a bit slower than LAN, while LAN is typically around 0.3ms (<1ms for windows peeps), wifi...

    Swtiching over from Powerline to Moca 2.0 - New Setup Help

    you would need to rewire the box, disconnecting LAN from WAN, and if possible having separate wires to the central point of your switching, but incase you're stuck with the same lines its not too bad compared to powerline. Highest i got with powerline was 10% rated theoratical. That means that i...

    rsync performance - 13 MB/s only?

    before switching cables. check your interface links if they are at 1Gb/s, however there are other bottlenecks like CPU and in some cases, overheads for syncing (checking the files not transferring) over the network. When you perform a rsync check your network and cpu usage. Some hard drives are...

    2 Routers on one Network

    completely wrong the article you read. You can have 2 routers on a network, but only with routers that have enterprise features as thats a feature of enterprise routers via a few types of features, but i doubt you'd be using BGP. You have 2 WANs, and you have 2 routers, you need a...

    Increasing cellular reception with passive antenna

    laptops with new compact antenna design that get great signal do something very very different. The problem is that the cable also acts as an antenna, you can have an antenna that specially designed for a frequency to be good at receiving it but bad at receiving other frequencies, but its in the...

    Increasing cellular reception with passive antenna

    I just remembered, the reason you'd use a passive antenna is if the SnR is bad but there is good signal. a passive antenna wont help much if the signal is too weak, but most of the time its the SnR that matters over the signal strength. Some modems let you pick a channel (frequency) which has...

    Increasing cellular reception with passive antenna

    actually cables have very high losses When it comes to mobile signals, the energy in the cable is so weak that its not like the coaxial cable tv/internet with a powerful transmitter and a limited path for the energy to go. with conductors, weak signals can be worse in copper or highly conductive...

    Increasing cellular reception with passive antenna

    passive antenna increases the path and therefore losses, so a passive antenna doesnt work that way. If the antenna is short(cable, antenna, everything) and more sensitive than it could help. Another alternative is to simply wrap some cable around the device, i've tried it before and it did help...

    Choosing a low latency router for Xbox One X

    the best router for lowest latency is one with CPU connected ports, and these routers require a lot of skill to configure. However at best you'll see a reduction of 2ms from what i've tested. Then you'll need to configure QoS and know which packets to prioritise ahead of the queue so they get...

    Intel Once Again Exits The Wi-Fi AP/Router Biz

    quite different really. Melanox takes the developer approach (you can code with the card), whereas intel doesnt. Different directions. I have a non working older melanox card :'(

    May Need New Laptop

    i used to like lenovo, not anymore. For me the biggest requirement for a laptop is thunderbolt, because many adapters are made use that so not having it is more of a problem as you dont want to have too many adapters, for which that same adapter can then be used for your phone too. my gripe...

    Intel Once Again Exits The Wi-Fi AP/Router Biz

    when i tested i had the router very near the adapter. so its more of ideal conditions, its how i arrived to the typical 50-60% of wifi AC link bandwidth being practical.

    Stacking UPS? (Without Transfer Switch)

    Yes you can link them directly on the output to load balance them but there are a few things you need to understand about passive linking. in EEE it only increases the max output by 20%, that means if you use thicker cables you could get 60A max. It will not perfectly drain them. It may drain...

    Intel Once Again Exits The Wi-Fi AP/Router Biz

    i've had a realtek USB-C gigabit ethernet adapter crash a network :p, it is that bad. on paper realtek looks great, but when using it its terrible. That said its important to understand where each brand flaws. intel has bugs in its wifi drivers that makes it unable to connect after sleep or...

    Intel Once Again Exits The Wi-Fi AP/Router Biz

    realtek beat intel by focusing on the media converter chip, and lets the CPU handle the rest. Intel NICs have a lot more features and usually work better especially for virtualisation, but in the consumer space intel has lost and as i mentioned bugs.
