I'm experiencing problems streaming video from my Diskstation DS212j to my Sony Xperia Z tablet via my Vodafone VDSL HG659 modem.

 

Video will stream ok for around 10 minutes, then continually freeze with buffering problems.

 

I am confused as to why this is happening as the streaming from DS to tablet is via the home wifi and does not relate to the underlying speed of the internet. We are in a small apartment, so the Vodafone wifi router is reasonably close to the tablet.

 

So any feedback will be appreciated.

 

Is it a crap router?

 

Is it the aging Sony Xperia Z tablet (I doubt it as it can handle streaming from internet ok most of the time)?

 

Is it a configuration issue with the DS (I use the DS file android app on the tablet to stream the video file on the DS)?

 

cheers

High quality video will always struggle over wifi. Here are some keywords I picked from your post and why they interest me...

 

wifi - please read the MANY MANY MANY other threads about how wifi can be affected but external influences.

 

apartment - assuming apartment building? think how many other wifi AP's there are around you. then see my first point.

 

Vodafone wifi router - probably not the issue. But there was a firmware update to do with wifi on one of their huawei models they were giving out. i think?

 

 

 

Basically, wifi is going to suck in apartments because there is just way too much of it around. The amount of bandwidth between your device and the router will vary greatly depending on many other factors. Probably looking at going to a 5GHz AP would be a good idea, and looking at a spectrum analyzer too wouldn't hurt.

Thanks - will check firmware and investigate 5 Ghz

Yup, that top link is a great util to have on a phone :) Check what channel your wifi is using and see if its congested with other WIfi traffic... usually in apartment situations (IME), all channels are reasonably well flooded so you dont really get much of a choice.

Is it pure streaming or is transcoding part of the process ?

Can you download a large file (1GB) over WiFi too ?

A.
