Mga master pahelp naman po. I\'m choosing between TL-WN851N <click here for link> and TL-WN781ND <click here for link>.
Here are the obvious differences:
851 - PCI, 2 antennas, 300mbps transmission rate
781 - PCIe, 1 antenna, 150mbps transmission rate
Then I did some research regarding the bandwidth of PCI and PCIe and found this site <click here for link>
1. Hindi ba nonsense yung 300mbps ni 851 kung 133mbps lang ang limit ni PCI?
Balak ko kasi yung 781 since mas mura siya (half ng price ng 851) pero 150mbps lang yung transmission rate niya
2. Malaki ba effect ng 150mbps sa internet, file sharing, online games, streaming, etc?
3. Which one performs better overall? May difference ba yung transmission rates nila?
Medyo noob yung mga tanong ko pero hindi kasi ako masyado familiar sa mga ganto, and minsan yung nagbebenta mismo hindi masagot yung mga ganyang klaseng tanong.
Anyway, thanks po ng marami sa makakasagot :)

PCI - 33mhz x 4 clocks = 133MByte/s
In this case, a WiFi N-Extended have 300mbit/s which is roughly 36MByte/s. So whats the buffling. Just get the PCI version since PCI-e network cards had nowhere to be used today. Unless, you want a 10Gigabit Network -
So the \"speed\" mentioned in the card is not 300Mbps but 300mbps? I\'m a little confused because the website says 300Mbps with a capital M.
Mbps is Megabytes/sec right? And mbps is Megabits/sec?
1 byte is 8 bits, am I correct?
So you are suggesting the PCI because of its 300mbps transmission rate? -
Yes, transmission speed shouldnt be confused to begin with, more like its a common sense. In analog signal, the amount of data is measured in bits.
But thinking about PCI-e, if its a x1 slot you can also get that one.
It doesnt really matter if which one youll be getting, its all about speed anyway, plus its only 100 peso difference for a additional 150mbps gain on a cheaper one.
Also do note that if you dont have a PCI-e x1 slot, you can put use the x16 slot (dont worry about the size of the interface) but youll be wasting a lot of bandwidth
but anyway, i still recommend PCI since all motherboard have PCI slots anyway, unlike x1 slots, not all motherboards have it.

nope...
MBps = megabytes/per sec
Mbps = megabits/per sec -
Actually I already have the 150mbps pcie x1 card. I\'m using it in my extra x16. The x1 is sitting too close to the gpu so I decided to put it in the spare x16 instead.
I asked this because I\'m thinking of having it replaced with the 300mbps PCI card. The difference is not only Php100, its double actually. The PCIe card is at 700 and the PCI card costs around 1,400 if I\'m not mistaken. I just want to get the best possible performance. If the price difference is worth the \"speed\" gain then I might consider having it changed. -
sir i hope hindi ako mabash :) pero gaya ng sa lagay ko sir ganyan din naisip ko pci or pcie wifi card, pero napaisip ako mas okay pag USB na wifi dongle nalang, in theory pareho lang sila ng function :) pero the good thing is pwede mo gamitan ng extension na (active) usb cable para mas maitaas or mairelocate yung dongle para mas maganda ang sagap ng signal. one good use din is pwede mo sya dalhin pag laptop mode ka sa ibang lugar. di hamak na mas malakas ung pagsagap ng mga USB wifi dongles kesa sa built in ng laptop, believe me ang daming nasasagap heheh :) so ayun, in short sir naka USB wifi dongle na ako sa desktop ko sa kwarto :) no problems so far :)

PCIe or PCI, it doesn\'t really matter.
Malaki ba effect ng 150mbps sa ...
+ internet, online games, streaming = NO (any old 54g is already too much for your internet speed)
+ file sharing = maybe YES (if only your router supports 300mbps)
To clarify...
- MB=mega bytes, mb=mega bits
- You can use your PCI-e x1 card to your PCI-e x16 slot. -
150mbps and 300mbps is good as long as nasa same room ang router, if may walls sa pagitan ng router and your desktop pc ganun din sir :( for sure bagsak din.
-
I\'m a little confused because the website says 300Mbps with a capital M.
although that\'s the standard terminology, IMHO it should be changed because having only a capital or an uncapitalized letter as the difference between 2 units makes confusing the 2 versions soooo much easier. Its much more difficult to confuse mbps (irregardless of the capitalization) with mbits/s
for internet, walang difference kasi bottleneck ang ISP mo. the only difference (if walang bottleneck sa loob ng mga PC) is in transferring large files over the network, doon mas mabilis if all wifi devices use wifi N 300. If one wifi device is wifi N 150, bottleneck sya
150mbps and 300mbps is good as long as nasa same room ang router, if may walls sa pagitan ng router and your desktop pc ganun din sir :( for sure bagsak din.
yes, low signal strength = lower speed -
@cabs
Thanks for the clarification :)
@lagur
I see.. So I should be fine with the PCIe x1 150Mbps card. Yung sa file sharing kasi hindi masyadong big deal kung matagal or mabilis. I\'m more concerned sa speed ng net. Kung same lang ang internet performance ng 150Mbps and 300Mbps edi stick na lang ako sa 150Mbps :) Thanks!
@lynkchiz
I was considering the USB pero wala din kasi ako laptop so talagang sa desktop ko lang siya gagamitin. And may nagsabi saken mabilis daw uminit yung USB wifi kaya mag card na lang daw ako hehe :)
@pcruztemp
Yeah its confusing. Should\'ve changed a letter or two para hindi madali magkamali (guilty!) haha.
Di ko sure kung G lang or N yung wifi router ni PLDT pero yun nga hindi masyado big deal for me yung file sharing speed within the network kasi hindi naman ako magttransfer ng malalaking files sa bahay. Yung net lang gusto ko mamaximize siya especially sa online games and video streaming. Wooden door lang mamamagitan dun sa router and sa desktop hehe, it wouldn\'t be much of a problem :) -
@sv20ian
why not just use a cable? since malapit lang naman... and im guessing your router does have LAN ports... and also mas stable ang wired keysa wireless connection. siguro max 50php lang magagastos mo sa wired setup. -
Minsan kasi nililipat ko yung desktop sa ibang room, dun sa may malaking tv hehe nakikikabit ako :D

silly guys
Signal Quality and Signal Strength are two different matters. Even me, I have a 30% signal strength with signal quality of 50%, and you know what? Im connected just fine, pings are just fine, no dropouts, full speed.
There are scenarios that na meron 100% signal strength but signal quality is around 30% lang, that means nagkaroon ng mataas na noise rate. Think about a 2 humans shouting to each other ear to ear.
Ans yes USB WiFi dongles might do a better than PCI or PCI-e since they have allotted 400mbit connection (hub/shared) na test ko na rin, I can get a full 300mbit connection via USB connection. Also, all computers do have USB ports anyway and hassle free installation. -
@sv20ian
Yes, you may be getting the right choice but 300mbps is probably better for your future needs like maybe upgrading your router?... something to think about :)
@polka
The idea of PCI/ex card instead of USB is like having a built-in device to your system like eg. Sound device.
Off course a usb adapter can deliver convenience but PCI card can deliver better performance (depends on the device we are talking about).
It\'s a personal preferences but I prefer PCI card for my pc connected to my e4200 v1. -
i dont see a difference between a PCI, PCI-e and USB WiFi devices anyway. It\'s not like a streaming device where you need a lot of bandwidth (like capture cards).
If performance, USB can do a lot better because of its flexibility, you can move it around by buying a 3meter conventional USB extension.
If it is latency, uptime, stability and whatsoever, it still just the same thing. -
Yes, flexibility comes it handy but I\'m talking about the power performance. If you test both any of your wifi dongle vs D-Link DWA-556 / or any linksys alternative to a same place with lots of walls and interference, you will see a difference. With regards of usb extension, you can also find wifi antenna extension as well but rare find.
Like I said earlier, it\'s a personal preference. Either you use usb extension for more flexibility (but some might see it not practical) or PCI card which is more neater approach (depends on your pc position that can be a factor for your signal).
I agree with you that they are the same in terms of latency, uptime and stability.

So far okay pa naman yung signal and surfing speed nitong PCIe card that I am currently using. Di ko pa lang natest sa online games. I just wanted to hear expert opinion regarding the matter that is why I asked. And yun nga parang napapaisip ako if I should get the 300Mbps PCI card in exchange for this but since wala naman masyado difference except sa file transfer, I guess I\'ll stick with this one muna :)
I really appreciate all your inputs, thank you :) -
so mga sir ask ko lang po mas ok po ba ang pci kaysa sa usb po?
-
^Pag USB, abala. Pag PCI, parang wala lang.
-
Nasira na yung usb wifi adapter ko. Bumili ako ng pcie wifi adapter. Yun nga lang n300 ang available sa mall na binilhan ko kaya napamahal. Pero sa experience ko ay mas ok ang pcie wifi adapter. Dahil n300 mas malakas ang connection sa wifi na nasa 3rd room ng bahay namin kung icompare sa dating usb na n150.
