Q: Why haven't we heard of you before?
A: We have not tried to market ourselves in the past. But we feel that the time is right for everyone to get the benefit of a great performing card, at a ultra competitive price.
Q: Compared to other brands, what is the difference besides the price & performance?
A: This is a hardware business, we believe those are the only 2 things that matter in the end. You know the competitors out there, there are just a few that innovate and many that copy. You as the customers decide who the innovators are, who gives great value, and which brand keeps the better connection wirelessly. We only ask to give us a chance to prove it.
Q: Are the cards certified?
A: The F20, F50, F20-PRO, and F50-PRO have a Modular Certification. which means it can be used in any host board.
Q: Do they work with Mikrotik router boards?
A: Mikrotik's Routerboards such as the RB411 or RB433 among other host boards are fully compatible with our miniPCI radios. In fact, they work very well based on our testing as well as feedback from multiple customers.
Q: What drivers are compatible with your miniPCI radios?
A: Our current miniPCI radios are based on the Atheros AR5414 chipset. Any driver that supports this chipset should be able to work with our radios. Madwifi drivers, that are open source, seem to be popular with our customers.
Q: Can we see the certificates?
A: Sure, you can access our FCC certificates and test reports directly from the FCC website using a company code of "VKV" for Dbii Networks FCC Website URL. CE Certificates are available at card description and on Support page.
Q: Why do the cards show 19dBm when the specs are much higher?
A: All our miniPCI radios currently have an offset of 7dBm to account for problems with some of the opensource drivers. Certain of these drivers are not able to set the output power higher than 19dBm. We work around this issue by having an offset in the output power. So, if your driver software reports an output power of 16dBm, the real output power is 16 + 7 = 23dBm.
Q: How are you testing the cards?
A: We calibrate and test every single card before shipping. We also performed compatibility testing with some popular host boards such as Mikrotik RB411, RB333, RB113...etc using the Mikrotik's Winbox interface. The R52 uses the ufl antenna connector, F50 uses the MMCX antenna connector
Q: When the card use under heavy loading conditions, we hear a slight hissing noise.
A: Yes, we have experienced that. Although this hissing noise can be irritating, we can gaurantee you this sound has no effect whatsoever on the performance.
Q: Can we use the F50 at 4.9GHz?
A: Yes, the F50 is also certified with high power for the 4.9GHz public safety frequency band in the United States. It can be used with an wide variety of high gain antennas in this band.
Q: The transmit throughput is less than expected. Why?
A: The F50 requires more DC power (over 5.5W during transmit) than our other cards. Please make sure your host board can supply this power. If you are using multiple miniPCI cards on the same host board, make sure you account for the power required by all of them
