Having just got fibre I'm a bit disappointed in the download speed over WiFi, I'm on a 80/40 profile and was expecting something close to that but only get 28Mbps down and 15Mbps up.
It was suggested I try the speedtest over a wired LAN connection, which gives 76Mbps down and 30Mbps up ! Why such a big difference between the two, slightly slower I would understand but 50Mbps difference !!?
The WiFi results are the same regardless of which device I use, an iPad, d/top dongle and laptop wireless card, each is capable of a max 65, 54 and 100Mbps respectively yet they all only achieve 28Mbps.
Anything I can do to bump up the speeds to somewhere close to the max ? Already tried changing channels and disabling QOS, the routers in the same room and about 8 foot from my devices - distance doesn't seem to have an effect though. It's one of the TalkTalk superrouters a Huawei HG635.
It's a black-art that I've still not nailed after a couple of months of trying.
If it supports 5GHz WiFi and your devices do then you'll get better speeds and less interference using that.
Otherwise pick the least congested channel for 2.4 GHz, you'll need 40 MHz channel width enabled if you can.
WiFi Analyzer on Android and inSSIDer on Windows (version 3 (4 costs I think)) are good for seeing what channels are being used.
When I've had things working well I've been able to max out my 152 Mbit cable connection over WiFi.
I did a speedtest at Uni over the wifi and only get 48Mbps each way. From a wired connection I hit per-user cap of 100Mbits each way.
I think Wifi is just a bit shit, tbh.
The superrouter I've been supplied is apparantly the dogs danglies.
It runs dual band 2.4/5 Ghz at both 20/40 Mhz all at the same time and at 802.11a/n/ac/b/g/, however it also looks like it's one of the shittest for wireless !
I didn't know there was a speed difference between wired and wireless, thought it was just limited by the speed of the cards, a slight difference I could live with but 50Mbps !! I've upgraded from 20meg ADSL to 80meg fibre and only doubled my wireless speed.
Reading online it appears part of the problem is my existing cards/dongle operate on the n and g protocol at 2.4Ghz and are limited to 54Mbps (which is the speed I thought I'd get) so upgrading to a faster card with a newer protocol should improve things but they will never reach the max speed.
Funny how the ISP's don't say the only way to get close to maximum advertised superfast fibre download speeds is by using a wired connection, but all supply wireless routers.
It is also a wired router....?
WiFi never gives advertised speeds.
Speaking as a network engineer, wifi is always shonky. Cables are always the best way, even if they're messy.
After a bit more research it looks like my adapters are old and don't support some of the newer tech.
Seems I can get a bit more speed by getting a dual band adapter that supports 802.11 n and ac, although from what I've read 'ac' can actually be slower than 'n' due to interference issues.
Quite surprised there's differences in speed between different 'n' class adapters, thought they all operated to the same specification so the speeds would be identical.
Aren't network standards based on highest possible theoretical speeds?
