Connect Obi200 through a PC wireless
magno_grail:
From your posting:
"You MUST follow their instructions exactly or you could brick your router.
Edit:
Just to be clear.
After you install their firmware it's still a router, then you re-configure it to make it a bridge."
They are not going to let me modify their router software.
On the Obi-WiFi information sheet I was looking at this: obi-wifi-adapter_ps-en.pdf
Still, I was not asking if there was more equipment that I could buy to make this work.
The Frequently Asked Questions are rarely helpful. What is the range of the ObiWiFi? "You may place the OBi202 with the OBiWiFi Wireless Adapter anywhere in your home or office with good Wi-Fi reception." Totally useless. Of course it can be placed anywhere there is good WiFi reception.
Can I use the OBi202 with OBiWiFi as a wireless bridge? "With your OBi202 (with OBiWiFi) connected to a Wi-Fi network, you can plug a computer into the OBi202's Ethernet LAN port a to get internet access." Except I have a 200 and want the Obi to connect through the PC or raspberry to the internet.
This would have been a lot simpler if the twits refurbishing the building put in phone lines. Even cellular phone reception is not good enough to transmit data from a pacemaker monitor.

How many adverts or spec sheets have you seen that do provide a practical, believable figure for the range of a Wi-Fi device? Please provide links to a few.
An OBi200 plus an OBiWIFI will not give internet access on the LAN port. That arises from a limitation of the Wi-Fi specs, not a flaw in the OBi200 nor in the OBiWIFI. That is explained at https://wiki.mikrotik.com/wiki/Manual:Wireless_Station_Modes#802.11_limitations_for_L2_bridging (which was linked to in one of the posts in the RaspberryPi forum I linked to above). The OBi202 can do it because it includes a NAT router which puts the LAN port on a different subnet from the Wi-Fi link.

Why do you keep referring to "modem"? There are no modems involved.
Get the dongle. Plug it into the OBi's USB port. Go to the configuration page for the OBi and enter the WiFi access point's WiFi SSID and password. That's all there is to it.
If it works, great, but again, trying to make VoIP work over a facility's multi-user WiFi system will be flaky at best.

Unless they have some other way to connect to the internet, the equipment I have is a WiFi router connected to a modem which connects to Frontier's internet. As far as connections go I only need to connect to the router wirelessly. All I know about their building is they have a WiFi connection.
I am sure you want me to buy more of your companies equipment but I do not see the point if it will not do what I want. The dongle cost more than the Obi200. WiFi USB dongles are cheap but they made the Obi200 only work with their custom dongle.
Yes, the problem with equipment "data sheets" is they are actually marketing publications so they are worthless. If I buy an antenna chip for a board the manufacturer usually includes information on radiation pattern and gain. They do not say "buy it and see if it works for you" or "it will work if it is within range".
I am not trying to get internet access with the Obi200 and a ObiWiFi-USB from the LAN port.
I wanted the Obi200 to access the internet wired through a PC or raspberry but apparently it cannot be done. Too bad the marketing sheet did not say it only works with a wired connection or their custom USB-WiFi. I would not have bothered with it. I do not know if the building's WiFi is strong enough in the room but I could add a repeater if necessary.
It may be flaky but at the moment there is none at all so flaky will still be better that what it is.

None of the people who have tried to help you in this thread work for OBihai/Poly and have no incentive to encourage you to buy their products. You were advised to get an OBiWIFI because that is the most likely way to achieve a simple working solution to the problem you have described. Most likely but not guaranteed because no-one else in this thread but you has knowledge of the route that the Wi-Fi link must traverse.
You have not responded to my challenge to come up with other Wi-FI products which publicise explicit range figures. I fully expected that because there are too many variables which affect the range and most if not all are outside the control of the manufacturer. The transmit power and receive sensitivity of the remote Access Point, the antenna gain of that AP, the orientation it has been placed in relative to the Wi-Fi dongle, the orientation and mounting of the dongle, the number, type and incident angle of intervening walls and other obstructions, the presence of reflecting items, the presence of other W-Fi systems, other equipment that uses the same unlicensed frequency band etc.
Unlike USB flash drives there is no standardised protocol for talking to many other device such as printers and Wi-Fi dongles. They require specific drivers. The OBi firmware cannot contain drivers for all possible Wi-Fi dongles on the market now and in the future. And as an embedded system it isn't possible for the end user to install a driver even if it were available. So the firmware contains drivers for the two Wi-Fi dongles that OBi market and support.
