The 100m light flashes but the 10m don,t flash even though connected but speed very slow

how are you checking this speed.
the speed you appear to be quoting at the computer is the speed the lan network socket is running at. it's probably rated at 10/100
some peripherals only have a 10M interface hence you only get a 10M reading and sometimes will slow the whole network down.
not sure what you mean when you send your network 'through the wall'. if that's using a powerline adapter, the connection between them often only runs at 10M. I've got 500m powerlines and they're often down to 10M, sometimes 100M but not very often.

hi,when the speed light flashes,is there a pause or is this a continous flash ?regarding missing a connection, that i very much doubt...

Some ideas.
First , go to the back of the machine, there is a panel about 6 inches square with a couple of tabs on it to remove that panel. Turn the machine off, remove the panel. Remove BOTH memory sticks. With the memory sticks removed, turn the machine back on and let it come to ready. Then reinsert the memory sticks and power the machine back on.

Second, Go to Xerox.com. Click downloads and drivers. Then enter M20i in the search box. Go to downloads and drivers and scroll down to the FIRMWARE download, It should probably be version 2.9. May be higher like 3.1. Anyhow, Download the newest version of machine firmware and install it on your machine.
Other things to try if one of the first 2 dont help.

Change the ethernet speed (auto, 10M half, 10M full, 100M half, 100M full)
Reset NIC card
Reset copier back to factory default
Clear all the memory in copier

The term terabyte is not related to speed. It designates the amount of storage capacity of hard drives. Ex.. if you have two 500G hard drives, your total storage capacity is 1 terabyte.

The available ethernet speeds are 10M, 100M, 1G, or 10G.

It is not a distance limitation of the switch, rather the cabling in the walls and ceiling. If the cable is Cat5 it can be up to 100M, but this can be drastically reduced with things like EM interference from fluorescent lights, kinks in cable and more. The switch auto detects the maximum reliable speed and this interference would cause it to drop to 10MBps. If you don't have a cable certifier (very expensive) you may want to consider simply replacing the cabling run with Cat6 following best installation practices.

The Flash is useful up to approximately six feet, after which distance the light is less effective. The Flash is good for close subjects in low light. The Flash is not good to use when taking pictures in large rooms with low light or night / evening scenes. When the Flash is used, the shutter speed is automatically faster to compensate for the light from the flash. This means less natural light through the lens. This can cause dark images in large rooms or evening scenes. In this case, TURN OFF THE FLASH and allow the shutter speed to automatically slow down to adjust for natural light. Your images will be more bright. Be careful, slower shutter also means more potential for blur from motion by you or your subjects.

It is possible you have the Flash Mode set to one of the Slow Sync modes (lighting bolt with the word Slow). Slow synchronization flash sets a slow shutter speed for the background exposure and fires the flash for the subject exposure. Since the shutter speed is slow, your subject should be still and the camera should be on a tripod otherwise blur can result. Since this mode should only be used when the above conditions can be met, you should use the FILL-IN FLASH (single lighting bolt symbol) mode for most situations that require a flash for correct exposure. Repeatedly pressing the FLASH MODE button will cycle through the various flash mode settings.
