| 886153 | 2010-05-19 04:52:00 | Hi, I was told that wireless might actually work at 10 or 20% of its stated speed on the device or its fancy cardboard box . Anyone done testing? I haven' tested many diff files . That I think would work even slower . For a one large 50MB file it was going at 1 . 85MB/sec . Not sure how this translate to 54 Wireless G Speed . Cheers . |

| 886154 | 2010-05-19 05:20:00 | If i remember correctly, G speeds are about 20-30mbit/s, N is about 50-70mbits Speeds drop drastically if you mix devices, so it is best to have an all G or all N network for best performance 1.85mb/s is about 15mbit/s. Were you transferring wireless client to wireless client? |

| 886155 | 2010-05-19 05:30:00 | Yup PC to laptop - shared HDD copying 1 file. Upstairs to downstairs directly underneath. Both G via a router. | Nomad (952) | ||
| 886156 | 2010-05-19 05:49:00 | I could get about 3.5MB/s on mine. Once you bring USB and overhead into the mix it is quite slow. |

| 886157 | 2010-05-19 06:31:00 | Bear in mind that 3.5MB is 28m/bit ... | Chilling_Silence (9) | ||
| 886158 | 2010-05-19 06:39:00 | Yup PC to laptop - shared HDD copying 1 file. Upstairs to downstairs directly underneath. Both G via a router. Your speeds sound about right then; wireless bandwidth is shared between all clients. So 15mbits x 2 = ~30 mbits which is about right for G. |

| 886159 | 2010-05-21 12:00:00 | I connected my old laptop to my router - 100Mbps. I got 50Mbps copying the same file. I double checked by by grabbing a 500MB single file - the same. So what's this thing about a 100Mbps, is 50Mbps sound about right? What do people get with a Giganet? My DVD drive provides 40Mbps. Reading and writing to the HD. |

| 886160 | 2010-05-21 22:15:00 | Well it seems maybe the old laptop has a limited bus and a 5400rpm HDD :waughh: Would like to know if any have tested speeds using one large file - PC to PC (not laptops) with a standard SATA HDD (not RAID 0) . Maybe the mobile devices could transfer much higher with S Korea's 1000Mbps Internet cos they use static HDs . |

| 886161 | 2010-05-21 23:12:00 | I'm not entirely sure I follow what you've done ... You do also realize there is 8 bits in a byte, and you need to make sure that you're comparing bits with bits, and bytes with bytes. 40m/bit per sec = 5m/byte per-sec. Even older slower HDD's are generally capable of sustaining that kind of throughput |

| 886162 | 2010-05-21 23:28:00 | I copied a 50MB and a 500MB file (separate occasions) from Win7 PC to win2k older laptop via my router thru a wired connection (100Mbps). The speed was avg at ~6.9MB/sec (under Win7 - show details) - times 8 = 50Mbps. I copied a similar file from my DVDRW to the HD on the PC itself (not via network) and that gave 40Mbps. ~4.9MB/sec stated by Win7. I'm gonna copy a file from 1 physical SATA to the other and see what speed I get :) |
