only when being used---and not all the time either....kind of hit or miss...prior to me switching phones (prior to using sage to stream to my client) I got network dropouts about 50% of the time the phone was used. Microwaves haven't affected me yet however.
JUC edit: oh yea, as the above post alluded to---do not use channel 6 (default channel). Channel 2 works best for me. |

I'm able to get a decent stream over wireless when I tweak this:
HKEY_LOCAL_MACHINE\SOFTWARE\Frey Technologies\Common\DSFilters\MpegDeMux\NumBuffers Default is 20, I changed mine to 2000. Really improved. Sometimes you may have to pause for a few seconds so the buffers build up again, but it's usually pretty smooth sailing. Using Linksys WRT54GX (pre-N). Huge difference in signal strength and speed at a distance, even with regular G adapters. |

That's on the client.
I also made the change on the server, to stream videos from a NAS device in another room to the server. Didn't quite go as high as 2000 on that one. Think I did 1000. Again the change was noticeable instantly, especially on higher quality video files... |

It seems that wireless streaming stuttering is caused by the laptop's power-save features when running on the battery. SageTV only uses ~800k/sec bandwidth for DVD Standard quality. I can easily get 3-4 mb/sec out of my wireless. On AC, I can max out my wireless with a large file transfer and SageTV plays perfectly smooth.
However, on the battery, I have problems. SageTV stutters badly and still only uses 800k/sec bandwidth. The kicker is that I can fire up an FTP transaction to my SageTV server and suck down the show at 2-3 mb/sec. Bandwidth obviously isn't the issue. I'm assuming that SageTV's method of streaming data to the client tricks the wireless card into thinking it can go into sleep mode when it shouldn't. Either that or the data stream is extremely time sensitive since the client has no buffer. Maybe wireless streaming would work better if the clients had a buffer and the server went balls-to-the-wall to fill that buffer instead of streaming the packets in real time. What do you think? |

I've experienced this scenario at my bro-in-laws... 2.4GHZ phone interferes with his wireless connectivity only when phone is being used

Bandwidth is totally not the issue with Wireless G
It has to do with signal quality and interferance with other appliances, be it in your home or possibly external. The same equipment in my old house performed pathetically! I would have 30% signal integrity and the wireless router was only 20 feet away! New house... no matter where I place the router it is 95%-100% Incidently, my MediaMVP with game adapter is two floors away from my WRT54G which is in my basement. I also can get descent signal from across the street at my new residence. I suspect the concrete walls in my old house and maybe 80 year old wiring could have been the culprit as to why performance was so bad. Quote:

I was going to say disable all power saving options. Both in the BIOS and from Windows and see if that helps.

I think what is happening is that the card senses that bandwidth usage is low (SageTV playback) and determines it can dip into sleep mode. However, SageTV packets are time sensitive, so when it does go to sleep, it misses packets, re-requests them, and causes stuttering playback. If the client had a few megabyte buffer and the server sent data as fast as possible, I think wireless streaming would work much better. You wouldn't experience stuttering as long as your connection could move data at 800k/sec or better. If your bandwidth got hosed briefly by moving behind metal/water pipes, turning on a microwave, or someone using a cordless phone, you most likely wouldn't notice with a buffer. |

I'm about to try Sage over a wireless connection. I've been running Sage for some time now, and I've just gotten my Linksys 802.11g up and running. Currently, my Sage server is in the family room on a 10/100 Cat5. I've got one client on the same wired portion of the lan, and I've order two additional clients for the wireless portion.
The signal seems strong all over the house, but I've got a booster on standby just in case. I'll post the results when the clients come in... |

FWIW, I remember a friend telling me that 2.4GHz phones usually operate on channels 1-10. Setting your router to channel 11 should prevent the phones from interfereing.

I'm curious: 2.4Ghz phones & their interaction with G were discussed above, but what about cell phones? Is it my imagination that having an active G network makes my cell battery discharge more quickly? My laptop doesn't seem to lose its connection, but the cell phone seems to go dead _much_ sooner. (Working harder to maintain its own connetion, perhaps? They used to do that when I travelled to an analog area vs. the digital cell spots around home.)

One thing that hasnt been mentioned is the encryption. Depending on what is used that can have a significant affect on wireless networks. On my setup at home I tried WEP 128, and 64 and with both of those it caused stuttering. I tried MAC address filtering with no encryption and it streamed just fine. I have not tried WAP so I cant say if that works better.
With encryption the sender has to encrypt data then the destination has to decrypt the data. This can cause significant slow downs on a network. It is not very noticable on internet connections but can cause problems with streaming. -Matt |

Both my computers were distant from the wireless router and I had problems all the time, wireless streaming was practically impossible without switching to an ad-hoc network. Now I've bought another WRT54G and linked it to the main WRT54G using WDS (Wireless Distribution System). I now have outstanding bandwidth between all systems and can stream anywhere. As the ports on the second WRT54G still work, I think I'm ready to order a MediaMVP and connect it by wire to the second router (which you can place anywhere).

Another thing to note:
Windows XP SP2's "Wireless Zero Configuration" utility can really muck up your wireless bandwidth. It will constantly break its connection with your access point to scan the other channels for alternatives. |

Media MVP with Linksys wirless game adapter
I noticed a couple folks on this thread running Linksys wireless routers with Linksys game adapters on their MVP units. I'm trying to get this going and not having much luck.
I've tested the game adapter and the router out (they are 10 feet from one another - 90-100% signal strength reported) - hooking it up to a PC I can download 2 gig files no sweat - stays strong, life is good. hooking it up to the MVP, it loads, connects and I can start playing a recorded show for about, oh, 1 minute. Then the wireless light on the game adapter goes dark and it's all over but the shouting until I restart everything. I've upgraded the firmware on both units to the latest, checked all the info I can on line but I'm not finding much on this issue - anything special need to be done on the MVP side I don't know about?

I just recently got a game adapter and ran into the same problem. Everything worked great for about 1 minute and then game adapter would lose the ethernet connection to the MediaMVP. The solution for me was to plug the game adapter into an ethernet switch and then from the switch to the MediaMVP. Now it works great.
