I have run this set up 2xE2000s in a Wireless Ethernet Bridge for over a year, about 1.5 years to be exact(if memory serves me right). I recently, out of the blue noticed that Wireless transfers have dropped from about 8-10MBps to about 5.5MBps. Nothing new has been added to the network full time, the routers have not changed position. Nothing at all has changed but suddenly my transfer speeds drop almost in half! I have not changed firmware in some time, so a recent firmware update is out of the question. Originally I thought maybe it was my HDD on my PC, but I have tried transferring from my Intel X25M G2 SSD and that made no difference. The main purpose of transfer is media to my "NAS" which is an old USB WD MyBook(3 years old?) connected to a WD Live Media Player. The WD MyBook was recently formatted, so that not a problem, and fragmentation on my PCs HDD(2TB WD Cavaiar Green SATA III) is not an issue either. Any suggestions how to trouble shoot this?
