What hardware do I need to upgrade to fix Wireless issue?
Hey everyone,
My laptop is getting a little old, I bought a Samsung NP-RF711 with a intel i7 CPU running 2GHz and 8Gigs of ram back in 2011. Currently, I am paying for 1Gbps internet with rogers and I am getting the full speed when I run tests directly; cate5E cable.(consistently 125-135MBps on speed tests) However, wirelessly my laptop will only get 25-35MBps.
1. Is there somewhere on my laptop where I can see if its current hardware is capable of 5GHz internet or just 2.4GHz?
2. Is it possible for me to remove and upgrade this piece, if so, does anyone have a link to a good product.
3. Is my 2.0GHz CPU to slow for the internet I've signed up for?
**other notes. my wife's laptop Samsung NP530U3B from 2012 intel i5 CPU 1.6GHz 4GB of ram. Is consistently running 80MBps wirelessly on speed tests.
I appreciate everyone's time and any responses to this message

I assume that your network speeds are Mbps, (bits per second), not MBps (bytes per second).
Your laptop supports 802.11b/g/n according to the model specs.
802.11n supports up to 600Mbps (in theory), but obviously requires an 802.11n access point.
The Samsung NP530U3B supports 802.11 a/b/g/n
If the Samsung NP530U3B is getting 80Mbps, then it must be running better than 802.11g, therefore you must have a 802.11n access point.
It looks to me that your NP-RF711 is connecting at 802.11g speed (< 54Mbps) and that a configuration setting needs to be adjusted on the NP-RF711 to use 802.11n rather than g.
If this is the case, it would be under the wifi NIC properties in the network & sharing centre.

It might be something as simple as changing which of the SSIDs on your router you're connecting to, some have different ones for 2.4GHZ and 5 GHZ wireless. Maybe one laptop is using one and one the other?

It is not possible to "just" upgrade the wireless modem on your laptop. It is too deeply integrated into the machine to allow for a simple user upgrade, or even a complicated technical one really. What you do need to confirm is that it is capable of connecting with 802.11n protocols on 5GHz to get the maximum connection speed. The current speeds you are getting are not too bad at all although they fall far short of the theoretical maximum.
If you are stuck with 802.11g on 2.4GHz, then you will have to put up with that or buy a new laptop. Six years is twice the normal commercial upgrade cycle, although plenty of home users run PCs that are ten years old or more without any problems.

802.11a using the 5GHz band does NOT offer a higher data rate than 802.11n or 802.11ac which use the 2.4GHz or 5GHz band.
2.4GHz band offers more range and is better with walls etc.
There is no throughput benefit to either band other than as described.
In terms of data throughput 802.11a is I think identical to 802.11g (also 2.4GHz) and offers up to 54Mbps (bits per second) instantaneous data rate and about half that as a practical maximum achievable throughput. It may well be exactly half but I am not sure.
The point of 802.11a was to permit more channels and to avoid the interference of the already widely used 2.4GHz band. 802.11a is often used by businesses using professional grade kit and professional installations. Consider it if you get too much interference on the 2.4GHz bands.
Now to your little problem.
If you are getting 35Mbps you are definitely on something better than a/b/g. The best that any of them can do is about half of 54Mbps and 35 is well over that so you must be on 802.11n since your machine does not support 802.11ac (According to Mr Saab D).
1. Check that your radio is not set on some power saving mode.
This is described nicely here:-
WiFi Remedies for Samsung Laptops | NotebookReview
Note the two sections on power saving.
You could consider a driver upgrade also described there but you may need to get in some expertise.
2. Test at a shorter range (say 5 feet) and report results.

For example, my laptop is connected via 802.11g to the wifi hub, and reports 48 / 54 Mbps, but I get only 50% of the download throughput (15Mbps) that my desktop gets, connecting via RJ45 to the same hub, using the same speedtest application to the same internet server.
So for me, the question is: is the reported 25-35Mbps from the wifi connection properties (which may report up to the theoretical maximum), or using a speedtest application, measuring actual throughput?

Only the speed test is to be trusted really, the properties as you said refers to the theoretical max.
You can get USB wireless dongles, but laptops tend to have few USB ports so tying one up permanently isn't a great idea usually.
Daft question but why do you need that kind of speed? Even HD YouTube is fine on 802.11g, although if you have many sharing the connection it will cause issues.

having just been all around the Wifi/router/powerline adaptor/ethernet cable domestic network setup I can add a little info here.
The incoming data stream to our home manages 37Mbs, this I have proved using a broadband speed checker. It measures both download and upload speeds. If I connect a laptop to the modem/router by ethernet cable I get the 37Mbs. If I link to it wirelessly I get 37Mbs but only when the laptop is close to the modem/router. Go into the next room and it soon starts to slow down. If I use a pair of powerline adaptors (push the data steam through the mains wiring) I get 12Mbs in most rooms in the house but it doesn't work out to my workshop in an outbuilding.
The laptop has both 2.4Ghz and 5GHz available.
On my netbook things are a little worse as it only has 2.4GHz available and we have a number of conflicting signals from neighbours overlapping our channels on 2.4GHz. As a rule of thumb, the signal to my fastest machine, running Linus Mint, as reported by it's network driver, is only 68-70% (don't know if that is a quality or signal strength figure) and the link delivers a consistent 20Mbs between the back bedroom window and the out building workshop.
If you get signal conflicts from neighbours equipment speed falls off very quickly. On my netbook I have a freeby (may be not free anymore) called Inssider that uses the wifi and or GPS hardware in a PC to monitor and display local signal conditions. You can easily see what channels are in use and then log into your own router and move it to a channel which gives less conflict.
