Samsung series 9 and Intel h6230

Dear members,

My first post on the forums! I've used the search function and found alot of pages on this matter but none of the posts answered my question!

Recently I've purchased a samsung series 9 ultrabook and im struggling with the wifi. At this point my intel PRO wireless icon in the taskbar displays a speed of 120mbps. When I test my connection the real speed is 15mbps. My house is made of reinforced concrete walls and the AP is on the ground floor. My question is; why is intel pro wireless displaying a speed of 120mbps in the taskbar?

Also, my wifi is faster on 5ghz bandwith which surprises me because the 5ghz signal is way lower and 5ghz bandwith won't go through walls as easily as 2.4ghz.

Your opinions please!

 

First of all what Intel software is showing is the speed your are connected to a router- not the Internet. If you were connected with an Ethernet cable it would have shown 100Mbps or even 1Gbps (depending on your router).

Your Internet speed depends on what deal do you have with your ISP and is very unlikely to be limited by wireless connection speed (it isn't limited in your case).

As for 5GHz and 2.4GHz- the former having faster connection speed. It's likely because 5GHz network is working on a 40MHz channel (connection speed up to 300mbps for a dual stream router) while 2.4GHz is working on a 20MHz channel (connection up to 150mbps).

20MHz channel width may be due to lots of networks being present in your neighborhood (in which case 802.11n device should roll back to 20MHz channel automatically) or because that's how your have it set up on your router and wireless card.

 

Makes sense.

My max internetspeed is 60mbps. I reach those speeds constantly when I use my laptop with an ethernet cable and when I stand 1 ft away from the router.

They only network that could be interfering would be the neighbours, but the signal is very weak. I've setup my router to send out a 2.4ghz 40mhz signal and my wifi card is setup to accept the 40mhz line.

Bottom line: it's normal that I dont get the max 60mbps on the wifi signal?

 

Not really- 60mbos should be possible with a correctly configured wireless.
With 2.4GHz Wi-Fi set up to 40MHz and the same setting changed in advanced setting of your Intel card (available through device manager)- do you get 300mbps connection?
Make sure that energy-saving features are not enabled for Wi-Fi (on your laptop) and that your router is set to max transmit power (if the setting is even available).
Also make sure the router is placed correctly- high enough of the ground and with proper orientation of antennas.

What router is it?

 

In other words;

What I understand from you that the wifi icon gives an indication for the datalink speed between the laptop and the AP and gives an indication for the maximum possible speed. Possible but not always doable

 

Yes but 60mbps should be doable. check my post made immediately before yours for more questions.

 

ps. I checked the power settings as well before posting. Currently im on the adapter and no power saving applies.

 

Did some more tests.

On the 2.4ghz bandwith I don'tget the 300mbps datalink speed. Not even when I stand next to the router.

problem pinpoint: good neighbour policy by ISP.

 

2.4GHz and 40MHz channel might be impossible due to some kind of interference or simply because one of the channels in question (you need two to get 40MHz channel) is overlapping another network.
Use inSSIDer to check if you are actually using wide channel (40MHz)- it will be clearly visible on the graph. If you are that means it's transmitted as 40MHz but your Intel adapter chooses to go back to 20MHz.

EDIT: We posted simultaneously- that means you need to choose a channel that allows both channels you need not to overlap with any active network. If that is impossible- you'll need to move to 5GHz for better bandwidth.

 

Ive connected to all channels. No difference sadly.

I've phoned up my ISP helpdesk and they blame it on the concrete reinforced walls and want me to switch to dual band modem with 2.4ghz and 5ghz signal.

 

That will soft of help- 5GHz fades quickly but offers good bandwidth (due to not being overcrowded) while 2.4 offers good range but less real-life bandwidth.
Still- you should be getting much more than 15mbps while connected at 120mbps- so that's not concrete walls that are to blame.

 

Jup, exactly. On some 'hot spots' on the second floor I get 35mbps when I'm lucky. On the ground floor where the modem is located I get around 45mbps. Not bad but could be better IMO. I'll connect another router for the 5ghz signal so my laptop can always connect to that channel and I'll get 60mbps everywhere in the house.

Thanks for the help downloads!

 

I know it sounds silly, but in those 'hotspots', is there a microwave or a DC motor between you and the router?

I know the frequencies are different but I have done many tests that show some microwaves as well as some DC motors, will provide enough EM interference to lower the quality of a wifi signal.

Lastly, just because you do not see any other networks, does not mean that there are none there. If a neighbor has their router set to not broadcast the SSID, then you won't see it unless you run a...

Oh, I see downloads has told you about running a scan...so skip that.
