My saga continues as I try fixing the constant disconnection issues with my PLDT uLTEra connection. According to PLDT's email this is how we can speed up the internet connection.
LOLI have come to a point that the indoor modem should be replaced with an outdoor type thinking that this would resolve the disconnection issues.
Please do not try my desperate moves below, this is intentionally done to fry the modem. I'm only sharing it so that you don't have to perform the same steps.
- Desperate move number 1. Plugging in my laptop's power adaptor rated 19v at 3.4A on purpose to fry the circuit board of the modem, and have it replaced with the outdoor type modem, to my dismay the thing still works fine even though the adaptor that came with the modem/router is only rated at 12v at 1.5A. I left it plugged in with the higher rated adaptor for 30 minutes and it's still working.
- Desperate move number 2. Restoring the router firmware of the modem, and in the middle of restoration I removed the power cable. I was amazed that the Gemtek WLTFSR-115GN modem is still working after plugging it back.
I kept on checking the router settings and came across with MTU settings. Currently it's on 1400 and based on the KB article of Linksys.
"The Maximum Transmission Unit (MTU) feature of your Linksys router is an advanced configuration that allows you to determine the largest data size permitted on your connection. Generally, if your MTU is too large for the connection, your computer will experience packet loss or dropping Internet connection."
How to check the correct MTU settings of your PLDT Ultera.
1. Open an admin command prompt and type ping [URL] [-f] [-l] [MTU value]” and press [Enter]
2. Check the current MTU settings of your router and use that as the initial MTU Value mine is set as 1400
3. Keep on running the ping command until you get the correct MTU value by getting a reply on the website.
4. Once you have the value add 28 to it so it would be 1344 + 28 = 1372 that would be the MTU settings for the router.
After adjusting the MTU settings of the router I think that the disconnection issues has lessened. This is based on my personal experience or maybe PLDT has done some changes on their settings to make the connection stable. You can also try changing the MTU settings of your router and see if the performance will improve. The screenshot below shows that my router has been connected for more than 5 days straight no disconnection and power cycle is not needed.
As for the capping and utilization our consumption is around 40GB / month, and the speed is around 1 Mbps even after reaching the cap.
Location might be the key in having a good wireless broadband connection and as of now this looks pretty stable for me since the base station is near my area. The technology is new and I'm giving it a chance to reclaim itself besides we don't have any alternate options for now.
