I had a 150mbps G 2.4 USB adapter. It's ok... it works. It has a high-gain antennae and get's about 4 bars when connecting to my router. Average ping about 20m, 30mbps/3.4Mb down and 5mbps up (about half my connection when plugged directly into the router.) No packet loss.
So I bought a Wireless N USB adapter, it's dual band, 2.4/5. 300+300mbps. I plug it in, it gets IDENTICAL performance to the 2.4 USB adapter with the high gain antenna. The router is set to mixed, 2.4. So, I figure setting the router to 5ghz or N wireless only might help, since surely there would be some measurable differences between these two adapters. When I change it, I can only get one bar (when I'm able to connect,) and my mbps down is decreased to 5, and my ping sky rockets. What's the deal here? Why would operating at a wider frequency cause such a massive performance decrease? If I can only operate properly at 2.4ghz then I may as well ditch the idea of using N. I thought N would allow me to play games without hard-wiring. |

first of all usb adapters are not the greatest. if you had high gain antenna before and you don't know, that is one key factor.. make sure you are using the latest wireless card driver for the new usb device
2nd. what model router are you using, are you running the latest firmware? can you post screenshots of your wireless web pages? basic and advanced settings? having other wireless G or other wireless devices with "slow" down wireless performance have you tried different wireless channels? Don't use Auto select you will have hit and miss performance with this |

Quoted:
Everyone says quit using USB adaptors, yet all of the latest and greatest adaptors are USB including the Asus Black Diamond. The days of PCI adaptors is about over, its a dying technology. They didn't even sell any at Best Buy. The new adapter is a Netgear N600. Regarding the router, it's a Cisco/Linksis E2000. |

Ok so you have a router with internal antennas and a client with an internal antenna. And this.... Quoted:

I'm assuming that you are saying that it is 802.11g but, you also say 150Mbs. 802.11g has a theoretical throughput of 54 Mbs. Try this: Reset the router and adapter to default settings. Place the router and client near each other. On the router, set it to 'N' only, 40mhz bandwidth, 5Ghz band and get back to us. |

Turn off other adapters. Some network protocols will force the router to "step down" to the other protocol. They do not always mix. Your neighbors can interfere too, depending on how close they are as well. If your computer shows a bunch of other wireless networks you may be out of luck. If you want performance, you need to go wired. Period. Also, what does it matter? Unless you are transferring large files locally on your network, your wireless is doubtless faster than your internet connection is and it doesn't matter. Where exactly are you testing? What are you testing with? Don't test through your router out to the internet, that adds a whole set of complications. What the card reports the speed is to the operating system doesn't really matter. And unless you connect a wired computer through your router and test to that, your test isn't valid. You need this: computer ––- wire ––- router -\-\-\-\- wireless that you are testing -\-\-\- computer And then an app you can trust or just a large file and transfer timing using a stop watch.

I haven't had time to do anymore tests, but to answer your question, I have several wired systems. They all download the max (6.4Megs a second.) My wireless is half that. My problem is I think I was sold a bill of goods about N-wireless being so much better than G, and that I could play games on it "just like hard wired." |

You were not sold a bill of goods, hell even B/G can be as good as your wired computers as your max as you have stated is 6.4 which is your Internet bottleneck. I will be dollars to donuts you have some interference either in your home or your near neighbors. It could be cordless phones, another wireless network or something else interfering. The other thing that can interfere is too many walls or old style lathe and plaster walls or other obstructions that can kill a signal. |
