Anyone use frontends on a wireless 802.11g network?

I do cause theres no cable in my room.

Backend is celeron 600 mhz with 256 ram and 30 gb drive ( have to LVM add the 80gb ) and a pvr 350. Free pc I got - old HP.

Its hooked to a wrt54g with 3rd party firmware.

My computer frontend in my room uses a wrt54g put in client (bridge) mode to get the signal. This works better than the airport card in my imac g5 20" which plays for a while but locks up sometimes killing my router with it! I have to restart the router!

Some how the streaming video over heats the 80211g in the imac.

Even with that setup occasionally the tv stream gets dropped. Does that happen for you guys?

Anyway to make it rock solid? Besides running cat5 which is impossible in my location.

Post subject:  Wireless frontends
I have a wireless setup... it works most of the time. Not sure what it is but there are times where I think the wireless frontends are causing my MBE to wig out.

I'm considering just biting the bullet and wire my condo. I've also been thinking of playing with either homeplug or HPNA since 10Mbps is enough to carry the stream to my frontend

Anybody running any of the pre-N wireless or the stuff some vendors are trying to pass off for WiMax?

But I thought 10mbs wasnt fast enough.

I have tried 802.11b which is 11mbs and it definitey wasnt fast enough.

The house I live in theres no way I can cut open walls to lay cable between floors. If only we had though about this when we built the house 5 years ago....

Wireless 11.b is not actually 11mbit dedicated, as you would have on a wire. Remember broadcast is inherently more prone to interference. I hear that at 11mbits you can only reliably get 4mbit. And I don't think the "11mbit" is full-dplex like a wire would be. All those packets you send cause the other end to send back an ACK packet.

MPEG4 is designed for rates up to 1mbit.

Yes. Usually due to prebuffering delays. I think this is a problem with the total delay on a wireless network (i.e. TCP packet ACK latency).

If you search around here for posts by me about wireless ethernet you'll find a fairly detailed discussion of the bandwidth and throughput needed. Since video playback is a "realtime" application you're dealing with hard deadlines. Even if the average data rate is high enough, that doesn't help if the delivery is "chunky". Buffering can smooth this out some but only to a point.

10baseT (10Mbit/s wired) ethernet is fast enough to stream video around the house if you don't have a lot of conflicting traffic (a roommate doing heavy on-line gaming for instance). The big difference for wired vs. wireless however is reliablity and consistency of throughput. The data rate for of 802.11b is average, but if you live in an electronically noisy environment, that maybe like an average temperature of 70F when the high is 110F and the low is 30F.

I am using a Dlink DI-624 Airplus Extreme G wireless router going to a Dlink G650 802.11g pcmcia card laptop (using madwifi drivers). I watch live TV and recorded programs from different parts of the house. Buffering is very rare as well is "choppiness". It streams no differently than my wired desktop.
Works fine for me. If you do a search as directed above you will see lots of posts including mine about this issue.
