Wireless itself will reduce in throughput on allot of factors.
Be it attenuation due to distance, objects or walls between the router and device and even line-of-sight.
Heck, the throughput will reduce with the sheer amount of wireless devices you connect to it.

Plus, things like Microwaves, Cordless Phones, other wireless points and even Radio's can cause interference on the frequency reducing the throughput.

However, most peoples Wireless points are far faster than their internet connections, so it's a non-issue unless you are the kind of person who transfer files over the wireless network between devices.

You live close to a cemetery ?

He's got a cemetery on the one side and Sanitätshaus Stähle & Co. on the other.

OT:

I haven't upgraded my internet connection (Alice/HanseNet, bought by O2/Telefonica) in the past 11 years due to laziness, but I plan to switch to a different provider and a connection of at least 30 Mb/s. This week I learned two things which changed my mind about my future provider though: Vodafone will buy the provider I wanted to switch to (Kabel Deutschland), Vodafone supports GCHQ's internet surveillance program Tempora. Result: I will switch to another provider, probably Telekom.

100 mbps

Is that like an ISP thing? Or can I, for example, do that too?

Your speed gets downgraded, like 8mb --> 1 mb.

Or, some people prefer to pay for the extra bandwidth, like $2 per extra GB.

love living in sweden <3

i have 1GB UL/DL speed, but no servers hosting speedtest goes up to those speeds :(
steam is the only thing that 'keeps up' with the pace

Wow, you win, lol. Dat ping. O.O How much do you pay?

Technically, anyone can do it.
My ISP does provide me with tools to do it though.

Try playing with your DSL modulation and see which one drops the latency the most or at all. - Some providers might leave interlacing on the line regardless of speed, some it will only kick in at higher speeds.
Alternatively you could just ring your provider and ask them about it.

Thanks for answering :) I'll try playing with my router tomorrow. I doubt the people from my ISP can help with anything above basic functionality, I don't think I'll bother asking.

included in my rent but it is... 200SEK, roughly 30USD (with todays conversion rate)
