connect with serial console cable and type "/system reset-config"

then start from beginning, but make sure that:

1. you don't change the tx-power settings!
2. you attach an antenna to the card before enabling it

if you didn't do these things in the first place, you might have already damaged the card

i mistakenly deleted my hotspot directory in the File list using winbox.exe, because when i type ftp://192.168.12.1 i get something like ftp://192.168.12.1/hotpost/htpp://192.168.12.1/login and tells me the page cannot be displayed that is why i want to reset the whole thing to start from a fresh. Please what do i do i am new to Mikrotik router .

Thanks.

i now have my hotspot directory back.

but what do i do to improve the signal strength. do i have to reset it or what i dont have a serial console

you don't need to have the cable, you can use Winbox and connect to the MAC address of the ethernet port when you have done the reset. The only reason for this is that you will probably also lose the IP addresses.

will this improve the signal strength or can you log in to the router and see what could be causing the signal loss?

Re: Signal Strength Dropped suddenly.

by normis
this will make sure that signal loss is not caused by misconfiguration.

you still haven't told us anything about the setup. please answer these questions:

1. what is the best signal you ever saw in this installation?
2. what kind of device is the client and how far is it?
3. did you change anything in the config? when did the signal get worse?

i have gotten a best as -30, the client i am using is about 100 meters away and then it could browse through the client, but now the client cannot see it anymore.

for the client i am using:
1. router board rb433
2. omni-directional antenna
i did not change anything in the configuration.

can you check it to see if you can improve it or see what is wrong?

it could be possible that the wireless card is damaged in some way. this could happen during a storm without properly installed grounding. if you have the opportunity, try to change the wireless card and see if situation improves

if i change it do i have to do any configuration? its just to slot it in.

Re: Signal Strength Dropped suddenly.

Posted: Fri Jul 17, 2009 12:21 pm
by normis
yes, put it into the slot, and re-apply the configuration that you need for this setup. probably you will need to set the SSID and enable the interface, then add IP address.

from your opinion do you think it will improve the signal strength . I want to try all possibilities before i change the wireless card.
what do you recommend i change it to. which option do i select. currently i am on 2412.

and please can you give the command to do all that? i mean to re-apply the configuration set the ssid and enable the interface and add IP address.

click on the "freq usage" button on the right, and see which frequency is used the least. try that one.

experiment will show it best, from current information, i have no idea why you have problems. it could be bad card, damaged cables, interference or any other reason.

if changing frequency doesn't help, try changing the card. be careful, plug in the antenna cable, and only then turn on the routerboard.

Please give me the commands and step-by-step instruction to get the new card properly configured, so that i don't make mistakes.

Please i need your assistance here.

connect with winbox, go to "Intefaces" menu, double click on the wireless card name, enter the SSID that you need, click OK, then click on ENABLE button. Any client will be able to connect now. You can even leave the SSID as default, just make sure to enable the card. For getting a signal reading, this will be enough

thats not the problem

omnidirectional antenna!



static plays a role on this i had this problem befor are your omnidirectional antenna earthed in any way
if not add something above your omnis like this

and earth to the ground

change to pannels if you realy need an omni use this saves the radios

http://flakey.info/antenna/omni/quarter/omni_tech.jpg


in some areas omnis just kill the radios and some areas work well

hi everyone, well i had a problem with my signal strength, it was excellent say from 100meters away from the antenna, but it suddenly dropped, even if i stay very close to the antenna it still was giving low signal strength. so i thought it was the wireless card that may have gone bad so i changed it with a new one, but after changing it with a new one it still is giving me very low signal strength.

Please the gurus help me out. could it be some configuration problem or what?

help me out

thanks
