I have two user accounts from my service provider. He connected my network using something called TP-LINK Model No. TL-WA5210G. Can I connect my both accounts at once in the same computer?
That's a bit confusing, because the TL-WA5210G is a Wireless Outdoor Router. Anyway, you can not use both accounts at the same time and it wouldn't make sense, because the bandwidth is typically limited by the hardware, not the account.
