So that's some tough work, and therefore takes time.Īccording to the current 'TODO' list for the r8712u, it still needs integration to the mac80211 and lib80211 Linux wireless layers. And they do this without signing a NDA agreement nor even being offered a free device for testing/development. This forces the volunteer Linux driver developers to rewrite almost the entire Realtek driver for mainline inclusion. They also don't assign any human resources if/when the driver is brought into the 'staging' area.

Realtek (the maker of that wireless chip) is somewhat Linux friendly, and they typically create a Linux driver, but they have an annoying habit of using very little of the current Linux wireless/network infrastructure in that driver. This is where drivers that are 'outside of the kernel' are first sent to get them into shape for inclusion in the main Linux source code tree. The r8712u driver is in the 'staging' portion of the kernel tree. Blinking Christmas lights can reduce Wi-Fi performanceby 25% when it is close to the wireless router.The only suggestion I can give is to simply wait for a while. Alsoobjects near the wireless router such as metal filing cabinets and otherelectrical appliances. Building materials will block wireless signals such asplasterboards with metal foil, reinforced concrete walls and floors. Depending upon the location of large mirrors will reflectwireless signal away your computer.9. Fish tanks will cause massive Wi-Fi shadow on the otherside of the tank from the wireless router. Power cables located near the wireless router can causedrop outs and speed reduction.7.

Bluetooth devices, newer Bluetooth devices can jump todifferent frequencies if there is a connection problem.6. Wireless speakers and console controllers can causeinterference with the wireless router.5. Microwave ovens emit interference in the 2.4GHz band.4. Analogue video senders used to send audio and video toother TVs in the home.3. Many manufacturers choose channel 6 as the default.2. Many wireless routers are using the same wirelesschannel.
