I live in a lead lined shipping container?

I recently changed ISP from BT Infinity (UK)to SSE. Both offer VDSL fibre (75mbps). The modem/router supplied with BT was a Home Hub 5 which seemed reasonably good. Since I've switched my WiFi has been appalling. I have tried four different routers now:

Technicolor TG582N
Asus N66U
TP-LINK TD-W9980
Buffalo N600

What I don't understand is that my line speed is fine i.e 70mbps down and 18 up. This is stable. On every router above, the WiFi download speed is around 6-8 down and 15-18 up. This is even whilst testing the device using WiFi overview (app) stood next to the router. My modem is the Huawei HG612 which I unlocked. The router firmware's have been up to date.

How in Gods name can the wifi signal be this bad on all four routers? I have turned off all devices that may cause any interference. I have rebooted the modem and router each time. What else can the problem be?

I am not aware of any hadron colliders being operated by neighbours? This is driving me NUTZ!!!!! Just to be clear If the line speed is okay to the router I take it that the WiFi issue is merely a router problem (or something else)?

Has all your testing been with one client or have you tested laptop(s), tablet(s) and phone(s)?

I have tried on three different android phones.

What does the speedtest app say? I have never used the WiFi overview app.

 

[my_little_behemoth]

It shows the signal as strong, around 150mbps next to router and around 45dBm. (5ghz) a little better on 2.4ghz. When I use a speedtest app though the results are poor (as o.p)

 

[kanewolf]

You get the same performance on 5Ghz and 2.4?

 

[my_little_behemoth]

5ghz 81ms ping 1.29 down 6.5 up.
2.4 61ms ping 1.19 down 18 up.

My phone is 2 ft from router?

Seems that android wifi is shit. Laptop gives full speed. CLOSED.
