Hello! I recently moved into an apartment and activated 50mbps Comcast internet. I opted to use my own Modem and bought the Zoom 5323 which uses 2.4ghz http://www.zoomtel.com/products/5352-specs.html. On LAN I get about 59mbps

While standing near the modem, I get no more than 15mbps on WiFi

" alt="" class="imgLz frmImg " />

I tried changing my channel to see if it made a difference, but still not get any higher than 15mbps. Here is a pictures of a network scanner showing the channels.

And an image of the different channels and I can get wireless to broadcast on.

What do I need to do to get better WiFi download speeds?? I had a router that broadcasted on 5Ghz and it didn't seem to make a difference. Shouldn't I be getting more than 15mbps on Wifi?

The best thing to do is try another device on wireless like a tablet or phone and see what speeds you get. It is probably normal since I pay for 30Mb download but on wireless only get up to 16Mb download.

Your pictures did not post.

An apartment house is a difficult environment for WIFI. 5Ghz should be better because fewer people have it. Is the device you are connecting with a dual band (2.4 and 5Ghz) device? Some laptops (or tablets or phones) are some aren't.

I have connected multiple laptops, decsktops and iphones and they all get lower than 15mbps dl speed.

That seems normal, a wireless adapter can only send so much data in radio waves as compared to a physical cable. Think of the amount of data that has to be sent through thin air 15Mb = 15 million byte = 120 million bits

I have 5mbps download and can play BF4 simultaneously on 4 different desktops and have Netflix going at the same time on the TV. Everything wireless. I have a great router Netgear R7000 and use Trendnet TEW-680MB wireless bridges.
I believe a much better router would help you out. You need to spend between 100 and 200 dollars. I recommend Netgear and Asus

Let me re-phrase, 15mbps is the fastest I can get, if I walk away from the modem I get around 3mbps. You can't tell me that 3mpbs dl speed when I have the 50mbps is normal. I had the same internet service, same plan at my old house, and I got 30-40 mbps on Wifi

Oh, I didn't see you mention that you had faster speeds at your old house. Are you using the exact same equipment- router and modem- as the old house?

At my house we had the comcast modem with a linksys router. When I first moved here I bought the same router and rented the same modem, and it had slower results. I switched to my own modem which has wifi as well and that did not fix it. I had this router http:// which achieved 30-40mbps download speeds on wifi at my old place, but here we were only getting no more than 15mbps.

Same questions here...

I'm guessing the low speeds are due to the amount of wifi routers using the same frequency to communicate. This isn't very uncommon, honestly. For a small example, people who use 2.4GHz cordless phones will notice a slight hiccup in internet speeds when the phones are ringing/being used. This is just on a much larger scale. Unfortunately, because wireless networks are so common, and most of them stick with the same frequencies, high numbers of networks with substantial traffic (namely apartments) will have significantly slower speeds due to the amount of frequencies that need to be sorted out.

To break it down simply, your computer is sending packets in all directions, looking for your router. Every computer that is active on a wifi network is doing the same. Your router has to filter out all packets that are not meant for it/share the same network information/etc., in order to deliver your content. Because of this, your wireless speeds will suffer. The reason you do not have as much of a problem in a house is because the density of computer/network traffic is significantly lower. Using dual band connections can help, as long as everyone else isn't doing the same thing.

If you need the faster speeds, I would recommend hard-lining your network connection. Luckily, a speed of 13 Mbps is enough to stream most media without a problem (I have 8 Mbps at my house, and no one has problems with streaming on the network end, even when two users are streaming in HD).

Actually, wireless connections can reach much higher speeds than 15 Mbps, depending on the router. My wireless network is idling around 100 Mbps, using 802.11N (aka wireless N). With 802.11 a/g, speeds of up to 54 Mbps can be reached, with 802.11b reaching 11 Mbps.

Basically, 15 Mbps (as you put it) is considerably slow, as the screenshots show that 802.11n is, in fact, supported. Just clarifying :)
