I don’t know what my RipEX’s IP is – how do I connect?
Use the “X5” – external ETH/USB adapter and a PC as a DHCP client. Type 10.9.8.7 into your browser’s location field.
Alternatively, you can reset your RipEX to default access by pressing the Reset button for a long time, see Section 4.2.6, “Reset button”
. Afterwards, you can use the IP 192.168.169.169/24 to connect to the RipEX. Note that, in addition to resetting access parameters to defaults, your firewall rules will be cleared as well.
My PC is unable to connect to the RipEX.
In PC settings, Network protocol (TCP/IP)/Properties, the following configuration is sometimes used:
General tab - Automatically receive address from a DHCP server Alternate configuration tab - User defined configuration, e.g. 192.168.169.250
Use this configuration instead:
General tab - Use the following IP, e.g. 192.168.169.250
Verify your PC’s IP address from the command line:
Send a ping to the RipEX:
If the ping runs successfully, look for a problem with the browser configuration. Sometimes the browser may need minutes to make new connection.
I’m configuring the RipEX in its default state but it’s not working.
There is another RipEX with the default configuration in close vicinity. Switch it off.
I have configured one RipEX in its default state. But I cannot connect to another.
Your PC keeps a table of IP addresses and their associated MAC addresses. You can view it from the command line:
Start/Run/command arp -a IP address physical address type 192.168.169.169 00-02-a9-00-fe-2c dynamic
All RipEX’s share the default IP address but their MAC addresses are different, meaning this record interferes with your purpose. The timeout for automatic cache clearing may be longer so you can delete the entry manually by typing:
arp -d 192.168.169.169
or delete the entire table by typing:
arp -d *
Then you can ping the newly connected RipEX again.
I have assigned the RipEX a new IP address and my PC lost connection to it.
Change the PC’s IP address so that it is on the same subnet as the RipEX.
I entered the Router mode and lost connection to the other RipEX’s.
Enter correct data into the routing tables in all RipEX’s.
The RSS Ping test shows low RSS for the required speed.
Use higher output, a unidirectional antenna, better direct the antenna, use a better feed line, taller pole. If nothing helps, lower the speed.
The RSS Ping test reports good RSS but low DQ.
When the DQ value is much lower then it should be at the given RSS, typically it is a case of multi-path propagation. It can cause serious problems to data communication, especially when high data rates are used. Since the interfering signals come from different directions, changing the direction of the antenna may solve the problem. A unidirectional antenna should be used in the first place. Metallic objects in close vicinity of the antenna may cause harmful reflections, relocating the antenna by few meters may help. Change of polarization at both ends of the link could be the solution as well.
The RSS Ping test shows bad homogeneity.
Quite often the bad homogeneity comes together with a low DQ. In that case follow the advice given in the previous paragraph. If the DQ does correspond to the RSS level, you should look for unstable elements along the signal route – a poorly installed antenna or cable, moving obstacles (e.g. cars in front of the antenna), shifting reflective areas etc. If you cannot remove the cause of disturbances, you will need to ensure signal is strong enough to cope with it.
