Hello

 

I used to live in on place where I installed my whole network system (DIR 655 as main router, and 2 other DIR655 as access point)

My unraidserver was connected to one of the access point, and I was streaming movies to my TV through a WD TV live (wifi mode - N)

It was working fine...........

Now I live in a temporary lodging (i moved) and the equipment is a G modem-router

When I stream wireless, the movie starts OK for ~30sec, and then after stutters....It becomes unwatchable !!!!

 

Is the difference N vs G that creates the problem? I would have thought G was enough to stream movies (TV shows).

I also noticed that transferring movies (copy/paste) from my laptop thru wifi was slow (2Mb/sec max) while it used to be around 8Mb/s before on my N system...

 

Thanks

The problem is that the environment has as much to do with throughput on wireless systems as the actual protocol being used.  (The 54Mbps rate is the maximum rate and occurs only under perfect conditions!) The total spectrum space allotted to G is limited and the channels actually overlap.  The structure (construction type) and distance between the base station on the client can cause difficulties.  The number of Wireless networks in use in the area is another issue--- the more networks, the less chance of achieving maximum data rates.  The G band is also shared with microwave ovens which when in use can interfere with G transmissions.  The same bandwidth is also shared with cordless telephones.  Any problem with a link will cause the network to reduce its maximum speed until the link is stable. 

 

Other problem is that all devices on a G network have to share the available bandwidth.  (Each device does not get its own dedicated 54Mbs channel!)  Your system might work much better if you were to connect one or more devices using a wired connection to the router. 

G is plenty to stream movies, if there is no interference or other things using the bandwidth.

 

Rather than the difference between N and G, it is likely the frequency (2.4 gHz) is getting interference in your new location.

 

Both N and G may use 2.4gHz.  But N may also use 5.0 gHz, but not all N routers or devices will have a 5 gHz radio... many (like the iPhone) have only the 2.4gHz radio.  The router you mention, only has a 2.4gHz radio.

 

If the card in your unRAID box does 5 gHz N, try a router that has a 5 gHz N radio.

bubbaQ makes good point about interference and saturation.  Unfortunately if you're in anything like an apartment setting, all channels are likely to have extreme interference and overlap.

 

There are spectrum analyzers out there, "wifi analyzer" is a very simple tool for the android platform that can look at the wireless in your general area and see what channels are in use.  For example, there are 6 houses around me all using channel 6, and I'm the only one on 11.

 

5 gHz is still rarely used by many people, so typically it's quite a bit faster and cleaner (for now).

InSSIDer will help you select a channel:

That's an excellent recommendation. 

 

There are also one or two apps for Android devices that can give you similar information regarding channels in use by neighbours and their relative signal strengths (search the Google Play store for "WiFi analyzer").  Sadly Apple's walled garden means that there is nothing similar for iPhone as far as I am aware.
