AIS Fiber Upgrade from 200 to 1000 mb

Recommended Posts

I am in Pathumthani. We have had ongoing problems with our 200 mb AIS Fiber for the past month (slow or no connection). I am considering upgrading to their Supemesh 1000 mb. But they told me all they would so is swap the routers. The same cables would be used into the house and to the router. I'm not convinced.  Considering moving to True 1000 mb who will install new cables.

Assuming your AIS-provided optical router is working fine, log into the router's firmware and look around the menus for something called along the lines of Optical Power.   An AIS optical router (i.e., fiber optics line terminates right in the router) can operate properly/full speed with a incoming optical power of approx -25dbm to -8dbm....since we are dealing with power levels below 0 dbm a -18dbm level is stronger than a -25dbm level.  

 

Usually aprpox a -27dbm to -8dbm is the "downstream" optical power range for a typical home optical router....if the optical power is outside this range you can have problems.  That is, a downstream power level below the -27dbm like a -28, -29, etc) is too low and the power level higher than a -8dbm like a -7dbm, -6dbm, etc., can cause problems.   

 

And for "upstream" laser power (which your router generates) the range is usually +0.5 to +5dbm....notice no minus symbol now like we have with downstream power as were are now dealing with power levels above 0 dbm.   

 

If your optical power level is good, which AIS can also read/see remotely when you call in a problem to them, I expect the fiber line running from your residence to the junction box on the trunk line is perfectly fine.  If the power level is low chances are still good your line is "physically" fine but it's a problem at a junction box on the trunk line.   Within those junction boxes are passive optical splitters which can go bad.  By passive, I mean they do not use electrical power...the splitters act like a prism to split an incoming light beam into multiple beams.  

 

A fiber optics line running to your home can far exceed 1Gb speed...if it's in good repair there is zero reason to change it just because your are upgrading to a 1Gb plan.   AIS is not going to change the line unless they can confirm it has a problem---which is easy for them to check with a couple simple power measurements.

 

Happened to me about six months ago when my speeds got slow and erratic...but other times pretty fast and stable.  And sometime the AIS rouer Loss of Signal light would change from green to red....this means no or low fiber optics power arriving the router.  It was like Dr Jekyll and Mr Hyde.   

 

Since I can't get into my AIS-provided router firmware anymore to check optical power since the router is now set to bridge mode and now feeds my personal Asus router (years back I didn't have it set to bridge more), when I called AIS Support with the problem the first thing they did while I was talking to them is remotely check the optical power arriving the router as they can remotely access my router.  The support rep said the incoming optical power to the router is low....they will need to send a tech out.  It was a short and sweet call...I didn't have explain much at all....the rep could see the power level arriving the router was low which would cause my problem. 

 

When the tech arrived next day he disconnected the fiber optics cable going into the router and plugged it into his optical power meter....he was getting a power reading of around a -32dbm....too low.  He then then followed the line up the soi to where it plugged into the junction splitter box high up on the soi light pole about 125 meters from my home.  This particular junction box splits the fiber optics trunk line incoming fiber into 8 lines to feed out to homes.  Junction boxes can also split the signal 16, 32, 64, or 128 times, but the best I can figure Thai ISPs typically use 8 or 16 port splitter junction boxes--at least in moobaans. 

 

He unplugged my line from its port in the junction box and plugged in his power meter...he got a power reading of -32dbm reading...too low....same as on the other end of my line.   That means either the junction box was receiving low power "or" only my port was bad.  There was still one unused splitter port....he checked the power level at that port....it was good......plugged my line in to that port and my problem was immediately fixed...back to full speed.  He then tagged my old port as bad.   

 

A few days later several AIS techs came out to do maintenance on that junction box and the one upstream to it.  I lost internet for around 4 hours (and other hooked to those junction boxes) as they worked on these two junction boxes....bringing them down to ground level to work on them....replacing/repairing the passive splitter modules inside these black junction boxes. 

 

If your optical power levels are good then your problem could very well be with the AIS servers....your acct setup.   And just upgrading to a higher speed package is not going to help.   Probably best to get them to find and fix you current problem....if unable to do so just change ISPs if you can.

 

Take a look at below 2017 post for more info on AIS optical power levels.

Thank you thats very helpful. I have agreed to give AIS one more try to fix our problems by trying their 1gb mesh service. I found the login page for the router using 192.168.1.1 but I have no password.

192.268.1.1 is simply the gateway to your router.  Most routers default to using 192.168.1.1.....some 192.168.2.1...etc.   It's basically the front door to your router.....your local LAN front door.   You will need to logon (unlock) that door with User ID and password.   Sometimes it's as simple as admin and admin.  Other times it might be admin and part of the routers serial number.....sometimes it something like maybe a label on the router....or info in the router's manual....like maybe it's admin and aisadmin.  Once/if you do get in you can change the User ID and/or password to something else---just be sure to remember what you change it to.  If you enter the incorrect logon credentials you usually get locked out for X-amount of time....like maybe 5 minutes before you can try again.

By the way, I'll probably be upgrading to the Power4 1000/200 package early next week simply because I would save a few baht & get higher speed from my current Power4 500/200 package which I speedtoogle to 700/50.   Talked to AIS about it today....I'm still thinking about it....but I'll probably pull the trigger early next week.

 

Like all ISPs, AIS is always upgrading/changing its packages....sometimes you get an automatic upgrade....other times you don't and have to call and change which ends up locking you into another 12 month contract.  It's all part of ISP's "hook you for another year" game.

I got access to the router but I can see no mention of Optical Power or any number using dbm.

It that even a fiber optics router?  When I look up that part number it shows a router with a WAN port that for an ethernet type cable; not a fiber optics cable which is usually a small, round yellow cable. 

 

Maybe AIS also provided your Optical Network Unit (ONU) type device that the fiber optics cable connects into and from that ONU an ethernet cable runs to the WAN port on your H198A.   

 

If so, where the optical power level needs to be checked is within the ONU firmware menu if you can even access that.   

 

My current AIS-Provided router is a combo ONU & router....all in one device; not two separate units which maybe you have.

You are right. I have a Humax ONU box.

In that case you will need to see if you can find the logon credentials to the ONU.  You would probably need to connect directly to the ONU ethernet output port (i.e., the port that feeds a cable to your router). 

 

Then just like how you entered the gateway IP address and log on credentials to get into your router, you would do the same thing..  However, the IP address and log on credentials is surely going to be different.

 

Just for example if your had a Huawei HG8010 ONU (which you don't), below is how you would enter the ONU firmware and what the menu would look like showing optical power level.   And those "reference" levels is the levels the ONU can work with.   Optical power levels outside of those reference levels (limits) will result in loss of internet, erratic operation, slow speed, just weird stuff.

I have an AIS engineer visit Monday evening so I will be interested to learn what my Optical Power is.

Do you have any idea why I can't see IPv6 configuration options in my AIS Fibre Model: SR120-A modem/router.

I want to change the IPv6 DNS settings, like I did for IPv4 (see screenshot).

Like the topic starter I currently have 200/200 Mbps and I'm thinking to upgrade to the new 1000/200 package with the new SuperMesh WiFi router (http://www.ais.co.th/fibre/en/package_power4special.html) which hopefully has this IPv6 config option.
