Since the wifi link is low, did you see if the router wifi antenna was fully screwed in and in the same position as before? And why not a new router. Some just fail like that. Of course some ask why.
we have 2 families sharing 1 home. we have 1 cable modem & 2 routers. for over a year we had them setup as 2 completely separate networks each using their own router & password. 1 family accessed their network & 'net thru their own router & the other family connected thru their own router. there was no conflict & neither network could access the other. each family did their own thing as if the 1 household were actually 2 homes next door to each other.
there was some painting done in the home & all the computers, routers & modem were disconnected until the painting was completed. afterward, all equipment was put back exactly as it had been before the painting. each cable was labeled & marked prior to disconnecting so we are certain its all connected as before.
since the disconnection & reconnection, the 1st family is up & running just as before, but the 2nd family is only able to access the 'net VERY intermittently & when they do, the signal strength is VERY low.
what could have happened & how can we fix this? the family that isnt having problems is using a linksys router with both a wired and wireless connection with xp pro, vista & win 7 op systems. the family having issues is using a d-link wireless router with win xp home as their op system.
any ideas as to whats going on? thanks in advance for any help!
