could i increase my internet speed on my laptop with TWO wireless adapters to a router?

Question

i mean. i have a build in wireless adapter and i do have an extra slot for a another adapter. i was just wondering.

Answer 1

IF you could get them both to connect at the same time, yes, your speed could increase from your laptop to router. BUT you will still be limited by you DSL/Cable uplink, which is usually much lower speed.

Edit
Just to prove it to the naysayers, here is the output from my IPCONFIG

Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.0.114
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.0.1

Ethernet adapter Wireless Network Connection 2:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.0.102
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.0.1

Ethernet adapter Wireless Network Connection:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.0.101
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.0.1

There is a 'metric' associated with each adapter, it will use the lowest as long as it is available, but it will automatically use the others if the bandwidth is needed.

Answer 2

No - for a number of reasons

i) your computer will only communicate over 1 network interface at a time. for example if you have wireless and wired connections it will use the wired connection and ignore the wireless
ii) you do not have any native load balancing capability on the PC (this is used so that many servers can share the load (eg. on a E-commerce site)
iii) the 2 wireless adapters will interfere with each other, even if they are on separate frequencies/channels
iv) your uplink (cable or DSL or dialup) will likely be the limit of capacity

EDIT:- Gene M - you are correctly showing that each of the adapter can get an individual IP address. However there is not any inherent ability to share these in a default setup.
When each adapter has a different ip address any particular flow of information is from the source address to the destination. The source is the web server and the destination is your computer - so the information (such as a web page) only flows down one of the paths, not both. so no net gain by default unless you have load balancing to split multiple flows across the different interfaces
.
EDIT:-
Apparently It is possible to configure winxp servers (and computers) to load balance - see the links below. you can manually add registry entries to accomplish this which share flows between the adapters randomly.
I'm impressed that this is possible and I stand corrected - probably only for advanced users though as you have to edit the registry...
This will work for wired interfaces.
However, 2 wireless interfaces will self interfere reducing any gain in throughput. This is because the transmitted spectrum of one creates noise on the received channel of the other - reducing the performance significantly. While people in Wi-Fi talk about non-overlapping channels (1,6,11), they are not really due to implementation and a transmitter on channel 1 interferes somewhat with channel 11....)

Answer 3

Not genrally. However, there is software (generally meant for servers) that WILL split the load across two network adapters, either wireless or wired.

Answer 4

No it will slow you down because of the conflict.

Answer 5

i dont think so i think that will just give you viruses.

Answer 6

No

Answer 7

i dont believe so
