No, most WiFi equipment these days does not have a briding mode
[at least not in the shipped versions.] Some of the more stable and
reliable bridges that have been on the market for years are quite
restricted as to which systems they will connect to -- sometimes
only to the exact same model, sometimes only to devices by the same
manufacturer.
Wireless bridges that follow a standard and so should interoperate
[in theory] use 'WDS', "Wireless Distribution Standard". If a device
you are examining does not advertise WDS, then it isn't the right one
for you [short of replacing the firmware]; if the devices you want to
connect to are not WDS, then you might not be able to connect to them
from anything other than a device made by the same manufacturer.

I have no particular models to suggest at the moment, just general
comments:
1) Read the reviews in places like pcmag and tomsnetworking and amazon .
When I was last looking around a few weeks ago, it was quite
discouraging: the top-rated consumer-level 802.11g devices were
at 6 out of 10 or less in customer satisfaction. Mass sales is no
guarantee of quality.
2) Read the reviews again, and read the informal reports in places
like alt.internet.wireless and dslreports.com, this time with a view
to what customers are saying about their support experiences with the
companies. -My- quick summary, looking at those reports, would be
"If one of the devices works for you in -your- circumstances, then
Great! -- but that doesn't mean it will work for everyone. If you
are having a problem with it, and it is from any of the well-known
commodity WiFi manufacturers, chances are that you will be
disenchanted by the support organization, with a significant chance
that you will end up swearingly up and down that you will never
EVER buy from that manufacturer again."
Or to put things another way: If it works for you, then it works
for you; if it doesn't work for you, then be prepared to throw it
out (or sell it on eBay). You seldom get serious support attention
from a WiFi manufacturer unless you have paid several times the
going commodity-device price.

I think what you are looking for is an ethernet bridge or a workgroup
bridge.
One that will bridge multiple clients. The Zyxel g-405 is one example.
They should talk to any AP but there is no guarantee.

Since WiFi AP's these days tend to be more expensive than WiFi
routers, and because (according to Jeff Liebermann) most WiFi
routers have an undocumented "AP" mode which can be used simply
by plugging an ethernet cable into the LAN side and leaving the
WAN side unconnected, you may want to consider that direction
if price is an issue.

What I did, was connect a Wifi router to a 3rd NIC on my Linux firewall.
This way, Wifi is outside my firewall and the only way in, is via ssh or
VPN. I also have WEP enabled.

FWIW, there are some Linksys models than run on Linux and can be configured
to do things far beyond what the designers intended. There is even one
package available, that's essentially a "hot spot in a box", for use in a
coffee shop etc.

Most routers do NOT support client mode, however, which is needed for the
far end of a bridge, at least not without doing custom linux firmware
hacking or whatever.

I don't see the original question but I just converted Ethernet to Wi-Fi.
[1] I started with an old Windows 10 desktop that has no Wi-Fi card.
It was already on my intranet using its wired Ethernet connection.
But I wanted to move the desktop to a location infeasible by wire.
[2] I happened to have an old unused Linksys WRT54Gv8.1 router handy.
I'm told Linksys doesn't allow "client bridge" mode in that router.
But I was told that DD-WRT firmware does allow "client bridge" mode.
https://forum.dd-wrt.com/wiki/index.php/Main_Page
[3] I flashed the appropriate DD-WRT firmware onto that Linksys router.
(Firmware Version: DD-WRT v24 RC-7 (03/19/08) micro - build 9330M Eko)
https://wiki.dd-wrt.com/wiki/index.php/Linksys_WRT54G_v8.1
[4] I set up DD-WRT in "Client Bridge" gateway mode which was "paired" to
the home router by a MAC address to MAC address connection over Wi-Fi.

[5] This "wireless bridge" gateway connects my wired desktop to my intranet.
The desktop Ethernet port is connected by cable to a gateway LAN port.

A. Tested with an old Windows 10 desktop with only Ethernet (no Wi-Fi card).
B. Tested with an old Linksys WRT54Gv8.1 router (flashed with DD-WRT firmware).
C. Tested with a typical Netgear wireless router as the access point & router.
D. DD-WRT is set up as a gateway in "wireless client bridge mode"
The DD-WRT firmware converts Wi-Fi to Ethernet protocols (& vice versa).

Security = (write down the security), mine was "WPA2-PSK [AES]"
Passphrase = (write down the passphrase)
Gateway Router = (write down the IP address), mine was "192.168.1.200"

i. Just in case, enable your tftp client on your Windows 10 desktop PC.
You won't need tftp unless you can't connect to the Linksys via a web browser.
Run > control > View by small icons > Programs and features >
Turn Windows features on or off > [x]TFTP Client > [OK]
After a few minutes it should say "Windows completed the requested changes."

j. Assuming the Linksys WRT54Gv8.1 still has Linksys firmware, reset it.
a. Find a suitable reset tool (a cotton swab with the end cut off works)
a. Plug in the 12VDC 0.5A center-positive power cord
b. A moment later, press the reset button for about 20 to 30 seconds
k. To prevent mistakes, tape over the Linksys WRT54Gv8.1 WAN port.
You won't need the WAN port for setup, nor to use as a client bridge.
l. Connect the Linksys WRT54Gv8.1 LAN port #1 to the desktop Ethernet port.
Use the RJ45 connection on the Windows PC.
You can use any of the LAN connections on the Linksys WRT54Gv8.1 device.
m. From there, I followed almost exactly the directions found here.
<https://forums.whirlpool.net.au/archive/89059>
Using those directions, my results are reproduced below.
n. With a javascript-enabled browser, visit http://192.168.1.1
When/if it asks for your login information, use <blank>/admin to log in.
By default, you'll be placed in the "Setup > Basic Setup" tab.
Make a note of "Status > Router" information.
Firmware Version: 8.1.08 build 02 Oct. 26, 2007
Current Time: Thu Jan 1 00:50:43 1970 (GMT -08:00)
MAC Address: 00:1D:7E:A1:48:45
o. Optionally, additionally restore the Linksys WRT54Gv8.1 to factory default.
Administration > Factory Defaults > Restore Factory Defaults
(that did not change the firmware version when I did it on mine)
p. Upgrade the firmware from Linksys firmware to DD-WRT firmware.
Make sure there is adequate power delivery (e.g., on a laptop).
Then go to Administration > Firmware Upgrade > Browse
Browse to C:\<path-to>\wrt54gv8p1\dd-wrt.v24-9330_micro_wrt54gv81.bin
After a while you should see "Upgrade is successful. Rebooting......"
Maybe wait a few minutes before pressing the provided [Continue] button.
q. If necessary, log into the Linksys WRT54Gv8.1 router again.
You should now be in the dd-wrt System Information control panel.
Make a note of "Status > Router" (which will ask for your login/password)
User Name: admin
Password: root
This should put you into the "Status > Router Information" page.
r. Make a note of what this router information page is telling you.
Router Name = DD-WRT
Router Model = Linksys WRT54G v8.1
Firmware: DD-WRT v24 RC-7 (03/19/08) micro
Firmware Version = DD-WRT v24 RC-7 (03/19/08) micro - build 9330M Eko
(RC = release candidate)
s. The first thing to do is to change the Linksys WRT54Gv8.1 IP address.
Bring up the javascript browser to https://192.168.1.1
Press "Setup" and log in as root/admin (if needed)
Go to: Setup > Basic Setup > Network Setup > Router IP >
Set the Local IP Address = 192.168.1.200
Set the Subnet Mask = 255.255.255.0
Set the Gateway = 192.168.1.1
Set the local DNS = 192.168.1.1
Press Save & then press Apply Settings
t. Before you make too many changes, it's maybe a good idea to reboot.
Press Administration > Reboot Router
u. Now it's time to set up the router in "client bridge" mode.
With a javascript-enabled browser, visit http://192.168.1.200
(Whenever it asks you to log in, use root/admin as before.)
Go to Wireless > Basic Settings > Wireless Physical Interface wl0
You'll see this (but you will be changing that momentarily).
Physical Interface wl0 - SSID [dd-wrt] HWAddr [00:1D:7E:A1:48:46]
Set the Wireless Mode = Client Bridge
Set the Wireless Network Mode = (match that of the home router 2.5GHz access point)
Set the Wireless Network Name (SSID) = (match that of the home router access point)
Leave the Wireless SSID Broadcast = enable (it will go away soon)
Leave the Network Configuration = (this defaults to "Bridged") (it will go away soon)
Click Save and then click on Apply Settings and then wait for the router to respond.
v. Go to Wireless > Wireless Security
Set the Security Mode = (match that of the home router access point 2.4GHz SSID)
Set the Algorithms = (match that of the home router access point 2.4GHz SSID)
Set the Shared Key = (match that of the home router access point 2.4GHz SSID)
Set the Key Renewal Interval (in seconds) = leave at 3600
Click Save then Apply and wait for the router to respond.
w. Now it's time to "Join" (bridge to) the network you just set up.
Go to Status > Wireless > Site Survey
A new page will open and it should find your broadcast wireless gateway ssid.
http://192.168.1.200/Site_Survey.asp
You may need to press "Refresh" (but if it's hidden, it won't show up).
x. If there are more than one, find the correct AP you wish to connect to.
SSID = (same as your wireless gateway setting, e.g., MY_SSID)
Mode = AP
MAC = 8C:3B:AD:A6:B2:55
Channel = 3
Rssi = -81
Noise = -92
Beacon = 200
Open = No
DTIM = 0
Rate = 12(g)
Join Site = Join
Click the blue "Join" button for your access point, and wait a bit.
You should see: "Successfully joined the following network as a client: MY_SSID
Press the [Continue] button.
This takes you back to the wireless section basic settings page.
Scroll down and click Save and Apply Settings again and wait for any response.
y. You should now be connected to your gateway.
To check if you are, go to "Status > Wireless" and scroll to the bottom.
You should now see at least 1 MAC address and info including signal quality.
This will be your wireless gateway
Mac = 8C:3B:AD:A6:B2:55
Interface = eth1
TX rate = N/A
RX Rate = N/A
Signal = -81
Noise = -92
SNR = 10
Signal Quality = 15%
z. Test that you are now on the Internet via the wireless client bridge.
From Windows, the following pings should work.
ping 192.168.1.200 (this tests the connection to the Linksys WRT54Gv8.1)
ping 192.168.1.1 (this tests the connection to your home router)
ping www.google.com (this tests the connection to the Internet)
