How To Set A New Password On Dsl ? My Tenants Complain The Internet Too Slow ?

I feel the need to reply to this as well. 

DSL is not stone-age and not slow.  DSL technology came along before cable, it's maximum throughput is "slower" than cable by it's very nature.

DSL can reach speeds of 10 mbps.  That's typical of many home or office networks and not slow for most uses.  The farther you are from the phone companies central office the slower the speeds get.  You will typically see speeds that come close to that of a T1 line, around 700 to 1.2 mbps for download.

Cable can, in optimal conditions, reach 30 mbps.  You''l almost never see this is normal use.  3 to 6 mbps is typical.

DSL is aggregated at the CO, cable is a shared medium.  Both aggregate at some point and that's where any bottleneck will be.  Cable will slow down depending on the number of other users and what they are doing on your segment. 

Upload speed on either is a lot slower.

Next generation DSL is expected to reach speeds of ov er 4 mbps BOTH WAYS on standard phone lines within 4 miles of the CO.  And VDSL2 can reach 800 mbps to gigabit speeds at short distances.

Wireless on the other hand can reach speeds of 54 mbps, IF you can find a provider that supports it AND no one else is using it.  Otherwise expect similar speeds to DSL.

As to your tenants complaining about speed.  How many are there?  What time of day do they complain about?

For each user sharing your DSL you can effectively split the maximum speed by 2.  If they watch videos, download MP3's or play online games they will bring your DSL to it's knees.  The best speeds will be at night when everyone is asleep.

Your best bet may be to limit how much they can use.  Yes it will be slower, maybe even down to dial up speeds, but it will always be on.  The other option is moving to broadband cable or adding extra DSL lines and aggregating them.

Depending on the DSL router you use you can set access restrictions on it.  When I had DSL I used a Cisco SOHO DSL model.  That allowed for very fine control over every connection.

Other than that you will only be able to reset the account at your ISP that the DSL account uses to connect.  Change that from your ISP logon screen.
