I have just resolved some internet issuses with my ISP (TalkTalk - I will review their service in appropriate place later). Via Ethernet, I am now getting my 38/2 Mbps down-/up-load speeds as per package - my WiFi is awaful however, and I tend to use a powerline router with ethernet cable for my laptop, despite being only 4 m away from the router as the WiFi waves flow thro a floorboard & wall. In part, I suspect my laptop (a Samsung NP700Z5C-S03UK) - other users with eg Ipad & Lenovo get good wifi signal & speeds, an Asus however also struggles. Ok - I know WiFi signal strength & robustness is 90% art & only 10% science (physics). But I do wonder about the following: attached is a *.png showing the findings of Speccy re available WiFi where I am sitting.
1) belongs to my next door neighbour, & 2) is my current WiFi set up. 3) is the address (SSID) of our previous TT (TalkTalk) router used until a week ago, and 4) [I suspect] belongs to my TP-Link powerline extenders, even though I have "paired them" to the current router.
My question is this: are 3) & 4) interfering with my ability to get a good signal? I have used inSIDD to explore this a bit further, & I have manually reset channels, but with little impact - unless I receive evidence to the contrary, I believe the auto route is probably cleverer than I am in this instance ;-)
Partly as an aside - the TalkTalk branded routers are apparently Huawei HG635 - they receive mixed reviews (see eg http://www.trustedreviews.com/talktalk-super-router-review and http://www.pcpro.co.uk/reviews/wifi-routers/388996/talktalk-super-router), with the first one explicitly mentioning rapid drop-off of WiFi with distance from router.
Any not too technical thoughts out there
