2820n & Poor Results Using High Gain Antenna was created by tobiz
I've been getting v.poor results from my new 2820n using a single Ant-1107 High Gain Antenna, poor signal strength, long time to make connection, dropped connections etc. I'm using the high gain in the left or right connection not the centre one. I replaced the high gain with the 3 supplied short antenna and all problems went away. As I'm rack mounting the 2820n I can't use the short antenna. Question: do I need to use 3 high gain antennas to get good results??

I too have the same question. Do all 3 antenna ports need the antennas replaced? On some routers e.g. Billion, one of the antenna ports is the main RX/TX port and the other is RX only.
Can anyone advise if this is the same?

phez,
I asked Draytek technical and they said all 3 antenna had to be the same. I updated mine to use 3 high gain ones and the problems went away - however an expensive lesson!

Thanks Tobiz, thats a real shame because it is expensive and when you want to rack mount it its near impossible with 3 fixed antennas on the rear of the unit.
I wanted to place 1 high gain external antenna to capture all the traffic in the house. Any ideas?

802.11n using Mimo requires multiple (>1) antennae but maybe if you swtich to 802.11b or G only you will get better performance with a single antennae, as long as you connect to the right socket.

Thanks Admin, do you know which would be the right socket?
I have had a look around the forums and cant see anyone using the 2820vn with external antennas in a SOHO environment?
Looking at the below link, the draytek antennas dont stack up the best:

I bought my 2820vn with 5dbi antennas, have probably wasted money on that.
I am looking to buy something like this:
http://www.dlink.com.au/Products.aspx?Sec=3&Sub1=18&Sub2=38&PID=197
They are only rated to wireless-G. I have seen this for wirless-N
http://www.quickertek.com/products/80211N_upgrade_BS.php
It looks like it would work. Anyone tried one?
