Playback issues with Samsung TV and iPad

[aarpat 1]

I plugged in an ethernet cord, and that seems to have fixed the playback issue.  It seems like it's (at least partially) a networking issue, so I'll test out moving to another channel or to 2.4 ghz.  If there's no wireless workaround, I can run the wire permanently; but I'd like to avoid that.

Do you think it also might be a failure to transcode issue?  Is an i5-4570T with 8 gb of ram adequate to handle transcoding?

Thanks, everyone.

Edit: As another data point, I tested my ipad near my router.  I received 240 mbps down, but still had issues playing the 1080p-16Mbps file.  That makes me think something else is going on.  Although, for what it's worth, the ipad also shows up as 192.168.1.1 in the logs.  It must be some networking oddity with the linksys router.

230Mb in itself doesn't really tell you a lot.  Example, should it have been 400Mb but you're getting lost packets?  It's not really an indication of quality.

Another possibility is that you are getting interference which is corrupting the wifi data.  If you are close to a neighbour's router, for instance, or a bluetooth printer, even a microwave.  Changing band could well change the parameters of this enough to resolve the issue.

What is the model number of the linksys ?

Most modern routers/WAP's these days do actually isolate the wireless networks through some form of firewall/packet inspection/filtering even through they technically sit on the same LAN (aka micro segmentation).

There may be some options on the router/AP to remove the 'intelligence' for the emby source IP - allowing full speed to the wireless clients.

That's pretty close to my max download speed from the ISP, so I thought it would helpful.

I live in a larger building with multiple wifis.  I tested a few different channels, and it didn't seem to help.  Oddly, switching to 2.4 ghz seemed to allow playback without any issues.

Linksys model EA7400.  I quickly looked through the settings and did not notice anything about that.  But let me know if you see something I should change.  Thanks.

This is a big clue to your issues.  2.4Ghz is technically 'slower' than 5Ghz but it has much more 'range'  - if it works on 2.4, then it's just a matter of fixing 5Ghz or sticking with 2.4

On your phone, I would download a 'wifi finder' type app (I use Ubiquiti WiFiman as it's free and a great app) - and see what other devices are using the 5Ghz signal - and then change channel to one that is free and no overlaps if possible.  Do not use DFS channels unless absolutely necessary.

Looking at the manual for your router - it also has some advanced wifi-features that may be worth setting on/off.

Airtime Fairness - Boosts overall network speed by reducing traffic jams caused by slower devices.
Dynamic Frequency Selection (DFS) - If enabled, your router will use 5 GHz channels that are shared with radar.  When radar is using a channel, the router must switch and might lose Wi-Fi.  Another limitation of DFS is that the older devices cannot use it and will be limited to the router’s 2.4 GHz band when it is on a DFS channel.
Client Steering - Directs your wireless devices to the router / node with the strongest signal.
Node Steering - Allow your routers / nodes to always connect to the router / node with the strongest signal.  If you move a router / node or one goes offline, any connected routers / nodes will self-heal by connecting to the strongest signal available

Hi, has this advice resolved your issue? Are you still running into this?

[aarpat 1]

Sorry for not updating the post.  Switching to 2.4 ghz seems to have done the trick for now.  I'll let you know if the problem reoccurs.

Thanks everyone for the help.

Thanks for the feedback.
