Washington, DC | Wireless speed is half that of Wired I just switched from regular cable internet to Verizon FIOS Internet (+ TV). The provision is for 50 down/25 up. I get that speed when wired - actually consistently tested to 60 down/ 30 up. Which is great. But as soon as I unplug the cable and go wireless, it drops to about half, 25-30 down/17 - 20 up. This is not right. I know that wireless adapter has some overhead but I have never seen that much gets cut. In fact with my old cable internet of 25 down/ 2 up, I saw essentially the same speed wired or wireless. Any idea? Computer is about 10 feet from modem-router w/o obstruction, signal strength is 100%.
I used the least crowded channel (1) in my neighborhood - there is only one othet channel 1 wlan and it's far away.
Set router to N mode only already.
Any suggestion?
Equipment:
VZ's Actiontec MI424WR Rev I modem-router
EDIMAX EW-7811Un 150 N usb Wireless Adapter

| Wireless 802.11g theoretical maximum is about 24mbs, the protocols forward error correction uses almost half the available bandwidth of the listed best case of "g" 54mbs
N, if single channel can do about 2X this, but its also much more penalty to channel congestion |

Did you read his full post? He is working with all N equipment.
In addition, G wireless is a half-duplex protocol, therefore, half the throughput. |

Are you using the most up to date driver?

Are you using WEP, WPA, or WPA2?

All Win7 PC have worked fine for me without doing the optimizer. |

All my device drivers are updated.
I logged into the Actiontec router to check for firmware and it is already running the latest.
It is using WPA2 AES encryption.
Computer is win7 64-bit.
I ran the Optimizer but it makes no difference.
The thing is that when I had RCN, the wired and wireless speed are pretty much the same with wireless just a little lower. But with TiVo, the wireless speed is half off - both up and down! |

| Ok, where does the TiVo come in play? Is the PC running slow or TiVo? Need the full story. |

Your still getting the same wireless speeds, you said you got 25/2 on wireless with your previous provider, with Fios you get 30/17 wireless so its working at what your environment is limiting it to.
There are many factors to what is your wireless speed will be, distance, channel congestion, interference from other devices. |

I understand there are limitations, interference and overhead, etc. BUT a whole half of the speed disappears? That's a lot by itself and especially so considering I subscribe to 50/25 - that means 25/17 just gone - that's a lot of bandwidth that has vanished! I've never seen that before. I can understand and accept maybe 10% or even 20% but not 50%.
More importantly, the environment is pretty optimal:
The computer is about 10 feet from the VZ router.
Practically no obstruction in between.
I scanned the neighborhood and picked the least crowded channel - there is only one other network that use the same channel 1.
I have no cordless phone.
All my devices are wireless N, so no b/g to slow them down.
I just don't understand. |

kudos:6 | You're thinking about this wrong - it's not that some percentage of your speed is being taken away. It's that there's a bottleneck (the WiFi connection) and increasing any other part of the chain has zero effect because of the bottleneck. It's not an overhead problem.
I agree 25Mbps is very slow for 802.11n, but that may just be the best you can do given your setup and environment. Do you have any other wireless cards available (I don't trust those tiny little plug in ones very much)?
Do you have multiple computers? If you could transfer a file between a wired and wireless computer, you'd get a good sense of what the limiting factor is.
BTW, if the computer is only 10 feet away, why not just use an ethernet cable? Or do you mean the computer is 10 feet away while your testing it?

I am 99% sure that the slow speed is a result of the wireless adapter. I did a quick search on newegg for your adapter and some reviews are complaining about it being slow.
If you want to, temporary remove the WAP encryption and check if that helps the speed. |

Plano, TX | Have you tried channel hopping to see if any of the other channels get better speed? The only other thing I can think of would be to replace the wireless router if your adapter gets better speeds elsewhere, the Verizon ones are crap too. |

I'm curious to know how much difference this makes to speed. Can you explain? Chris Sure:

I think overall this is a fairly common problem with wireless in general. I have 35/35 service and the best I can do on wireless is about 20/20. I have a 'N' router. With a wired connection I often exceed 35/35. |

said by Thinkdiff:It's that there's a bottleneck ... that may just be the best you can do given your setup and environment. So, what is the bottleneck in your opinion? As you see my setup above, I can't see how my environment can create such a narrow bottleneck.
said by Thinkdiff:Do you have multiple computers? If you could transfer a file between a wired and wireless computer, you'd get a good sense of what the limiting factor is. I don't understand what you say. Yes, there are other computers and yes, I can transfer files among them. But how does this tell me what the limiting factor is. BTW, when I test the speed, I always turns off all wireless devices except the testing computer, just to eliminate other factors. I test the speed like this using all 3 of my computers (they all use the same wifi adapter) in turn. The results are the same regardless of computer used.
said by McBane:Have you tried channel hopping to see if any of the other channels get better speed? Yes, I have tried each channel. Channel 11 gives the worst result and all other channels give the same result.
said by sergey3:I am 99% sure that the slow speed is a result of the wireless adapter. I am thinking about that too. OK, I don't have another adapter on hand right now. I'll buy another to test. Any recommendation? |

How fast are file transfers between a wired and wireless computer? You can download any number of real-time network speed apps and watch the speed as you're transferring files. If you have multiple wireless computers (not using that same USB adapter), you can see if any of them get better performance. As I said and a few others have said, I think the limiting factor is your wireless card. Here are some suggestions. It's from 2010, but these should still be on the market: » www.smallnetbuilder.com/wireless···&start=3--

My friends in WV had a wireless dog collar that ran on 2.4GHz. The base unit put out a signal that kept the collar off. They hooked up a wireless router that interfered with the dog collar signal. The dogs were terrified of getting off the front porch. Once the collar started, the only way to stop the shock was to pull the battery. Proximity didn't matter any more.
Bad design.
Poor dogs. I felt bad for them. I sorta broke the router, but the dogs never got over it while I was there. |
