LAN port on Mobily fiber router

Recently, i disconnected from STC landline, which i have been with since 20+ years. Nowadays, it wasn't being used that often, only seldom someone calls. The only reason until recently was to have DSL which has unlimited data. But then, being in a location that doesn't support good speed, I was limited to just 4MB bandwidth. 

It was then Mobily started their fiber optic push. For STC was making me poor by 200+ each month while with Mobily I can have 10 times more speed (50 MBPS) for about 170+ (1,200/- for 7 months prepaid).  

So I went for mobily. Though I send them whatsapp messages and all, what finally helped me get it connected was after i contacted them through their twitter support (I guess). 

The technician made an appointment after a day or two since two guys came to collect the fee (1200 + 5% VAT). Technicians had a hard time pulling the cables but they finished it in two hours. It is better to choose an appointment in the day time if your appartment has difficulty pulling cables. 

After connecting, the technicians recommended a mobile app to be downloaded which consistently showed 50MBPS. I was more than happy.

Sharing few things I happen to find while using Mobily, hoping the reader may find it useful:

My laptop was placed a little away (about 10m) in a different room and the bandwidth fast.com reports was just around 5 to 10 where as I should get around 50. On my mobile I gets 50 if only I connect the one SSID that has 5G in its name (By the way, this SSID doesn't show up in my laptop). The router has 3 pre-built SSIDs. The technician told me the one with 5G in the name has lesser range but is fast and the other has more range but less speed. 

The modem we are installed with is from Huawei (so bigbigbro china tapping me round the clock?!) HG8245Q. Apart from the laptop and many mobiles, I wanted to use the LAN port in the router to connect a Pi and a backup HD. 

I was a happy camper until I found that if only I connect my laptop through cable, I would get 50+ speed. So with difficulty, did the wiring and connected through a cable. But alas, though there are 4 LAN ports available, after much misery with wrong diagnosis, I found only ports 1 and 2 works. Searching the internet for this router gave me the following knowledge:

Some of the operators disable all the ports and charges (don't know whether the operator or technician) 10$ per port for enabling them. Mobily seems better compared to them because they have enabled 2 of them. I saw some internet pages where mobily customer support replying that they have raised a ticket and thereafter nothing, which implies the customer got it fixed by mobily. 

Before going to their support, I did search further and found what I have been looking. There is an admin user id and password. Once logged in with that credentials, I could see that in one of the page (LAN something), only two of the ports got ticked. When I checked all the ports and restart, got it all working! For my relief now, my laptop too shows 50+. (Yesterday when i checked it went down to 14 but then I found a bend in the incoming cable which when straightened, the speed was back to 50+).

Anyone with any further tips ? Please comment.
