This blog post helps you solve common issues you may encounter when testing Network Address Translation (NAT) routers, or devices behind NAT routers.
From time to time operators or manufacturers ask us to verify how well a CM can cope with LTE interference. Will a cable modem / cable gateway suffer from a nearby wireless (LTE800) signal? How well can it withstand such a wireless signal? This post will dive into the wonderful world of (LTE) interference testing on cable modems. Will it survive 3 V/m, 5 V/m or 10 V/m?

Extended upstream power allows 3.0 cable modems to transmit upstream bursts at higher powers than previously established. This feature has been added some time after the introduction of EuroDOCSIS 3.0. But why? Do we need higher powers now than before?

TCP is an old protocol. Its original RFC dates back from 1981. Over time it has been tweaked and tuned in order to keep up with ever increasing demands. In this post I describe how one small tweak can make a big change in performance when using TCP on a 10Gbit Ethernet link.
More is better! It's true for many things, and the upstream frequency range for (Euro-)DOCSIS is one of those things, but like so often in life, it doesn't come for free. When considering extending this range it's good to know the benefits, possible issues you may encounter, and the alternatives. That is exactly what this article offers.

While most of us are using 802.11n devices or looking to replace them with 802.11n/ac devices, there are still some 802.11b clients wandering about. These old 802.11b devices can seriously impact the performance of our Wi-Fi networks on the 2.4 GHz band. How much? Let’s find out.
