Custom firmware, such as DD-WRT makes the process easier, and provides you with a lot of additional options as well; thereby turning a standard $100 router into a super router that is suitable for any home or office.
You'll see many websites that use the iconic Linksys WRT54G / WRT54GL for creating a super router, however, it's extremely outdated, lacks any USB ports, and so it's nowhere near the best DD-WRT router anymore.
While wireless frequencies are referred to as 2.4Ghz and 5Ghz, they actually vary a little from these frequencies on purpose. This is because for each main frequency a number of channels exist. These channels can be envisioned as the number of lanes on a highway. The more cars there are in a lane, the slower it tends to be. Finding an empty (or at least the emptiest one) is extremely easy, and it can help increase your range and your transfer rates.
Changing the channel, as described previously, is one of the easiest and most sure-fire ways to get a better signal. However, there are a lot of advanced settings that can be experimented with. These depend situation to situation, and some of them, such as increasing TX Power, can reduce the lifetime of your router. For this reason, you will not only need to perform some careful testing on each configuration you try, but should also bear in mind that other, more minor, consequences may result.
Ignoring the 160MHz, my router caps at 2400Mbps. Half of that is 1200, which is the same as the max 5GHz_1 channel performance on the XT8. What is the advantage of the XT8, in that circumstance Is there increased reliability with the separate wireless backhaul Because it sounds like they would have the same theoretical performance as using an XD6 with (non-dedicated) wireless backhaul.
Fixing the Channel for 5Ghz to 161 with VHT (80+80, upper+upper), gives a transmit rate of 54, nice boost but still nothing magical. Any channel >= 112 performs the same, but below 112 performance drops drastically.
For 2.4Ghz, typically channels 1, 6 and 11 are recommended, with 1 giving the best distance and throughput. And in my setup this is confirmed. Channel 1 performs best. But other channels are just a tiny bit below that.
I did some experiments this evening trying every channels in every extension, recorded the signal and transfer rate(i am using iperf to test the throughput you can get it for free) i will post the result tomorrow morning.
per this documentation Wireless starters guide for first time dd-wrt users higher channel allowed more transmit power output which usually increase signal quality, however based on what I have read the downside is on close range higher transmit power caused more noise.
I recently flashed my NetGear R7000 to the Kong DD-WRT in order to use the VPN service of Private Internet Access (PIA). It went very well, but I am not able to connect to the internet through an ethernet cable. Logging in the router goes just fine through both WifI en Ethernet and surfing the internet through Wifi also. I want to use LAN, as the connection is a lot faster than Wifi (still have to figure out the best channels for optimizing that). Any advice on why this is happening I always see the lights that reflect the status of the LAN ports on the router being orange instead of white. Here are the instructions that I used to configure the VPN: -support/dd-wrt-openvpn
Most bacteria exist in the form of a biofilm, which often contains diverse species that interact with each other and their environment. Biofilms are specifically microbial aggregates that rely on a solid surface and extracellular products, such as extracellular polymeric substances (EPSs).5 Bacteria move reversibly onto the surface, but the expression of EPSs renders the attachment irreversible. Once the bacteria are settled, synthesis of the bacterial flagellum is inhibited, and the bacteria multiply rapidly, resulting in the development of a mature biofilm. At this stage, the bacteria are stuck together, forming a barrier that can resist antibiotics and provide a source of systemic chronic infections. Thus, biofilms are a serious health threat.6,7 Moreover, the bacteria within biofilms can produce superantigens to evade the immune system. Therefore, despite the abundance of antimicrobial drugs and other modern antibacterial agents, bacterial infections remain a major issue. The chronic infections related to planktonic bacteria and biofilms are always difficult to cure because of their inherent resistance to both antimicrobial agents and host defenses. In particular, biofilms are less restrained by antibacterial agents than the respective planktonic bacteria are.8
Foster et al112 confirmed that titanium dioxide NPs can adhere to the surface of bacterial cells to produce ROS and damage the composition and structure of the cell membrane, thereby interfering with the function of the cell membrane and causing leakage of cellular contents, resulting in bacterial death. SEM has113 shown that treatment with TiO2 NPs increases the bacterial cell volume, causes honeycomb changes in the cell membrane, and causes cytoplasmic leakage. The surface of a bacterial cell has many pits, and bits of cell debris have been observed after n-ZnO treatment,101 resulting in reduced enzymatic activity and eventual bacterial death. Iron can also cause bacterial cell decomposition,114 and NPs can cause bacterial cells to aggregate, resulting in inactivation due to compression.115 Physical damage of bacterial membranes is the most important mechanism of the antibacterial activity of graphene. Tu et al116 investigated the antibacterial molecular mechanisms of graphene nanosheets against E. coli. Based on molecular dynamics simulations revealing the atomic details of the process by which graphene nanosheets induce the degradation of the cell membrane, the researchers concluded that destructive extraction of phospholipid molecules from the cell membrane by graphene nanosheets led to bacterial inactivation. Similar results were obtained by Akhavan and Ghaderi,117 who analyzed the interaction of graphene nanosheets with the cell membrane of bacteria. Specifically, the graphene was completely wetted in water by membrane lipids, and the dispersive adhesion between the graphene and the lipids played a dominant role during extraction.
There are still many unanswered questions regarding nanoneurotoxicity, such as how NPs cross the bacterial cell membrane. The bacterial cell membrane is both a barrier and a channel for the inward and outward movement of substances. In Gram-negative bacterial cell membranes, porins, which generally allow the passage of molecules
