I've got fibre in my house on a Huawei HG659 router and get 200MB/s over ethernet and 160MB/s over WiFi.

I've renovated our garage into an office and got my sparky to lay an ethernet cable from the garage underneath the house to the room where the Huawei router is located. 

Problem is I only get 30MB/s out in my garage over ethernet.

Its actually faster to use WiFi from my house out in the garage as I get 40MB/s over WiFi 

I suspect the reason is because I've got the ethernet cable from the garage coming through into the house via the old VDSL master filter that is attached to the wall in the house.

I suspect that the VDSL filter does something to limit speeds to ADSL levels.

If this is the case then the simple solution would be to bypass the VDSL filter and to create another hole in the wall for the ethernet cable from the garage to come through.

Would be great to talk to a Chorus technician. I imagine they could diagnose this in a second. Anyone know how to get in touch with one?

Or if you know the answer please let me know!

Thanks
