Router unstable on download speed

[Mhist]

Hi, I've been trying to figure out whats wrong with my wifi for about 2 weeks now. My internet subscription is 25 mbps.

Last week, I've been playing games like Dota 2 and CSGO and I'll start with 20-40 ping and it will go up like crazy until 400+ (500+ on CSGO). I check my speed test and I only getting about 15-17mbps sometimes it goes down till 13mbps. Before when I check my speedtest I normally get 26mbps. 1 mbps higher than what I'm supposed to get via Wifi but now its lower now. Ping is way higher than before too. sometimes I do speedtest and I'll get like 7-9 ping now I'm getting like 16-20 ping. upload speed doesn't have much changes.

 

It's unplayable so I decided to call my ISP (Lightspeed) for technical support. We power off both modem and router for 2 mins, open it up and check, still the same. We tried wired connection with the router, I still get the same result. When we tried to remove the router from the modem and did a wired connection (Modem doesn't have wifi) I got 8 ping, 26.75 mbps and 6.75 mbps upload speed with a stable graph once it reaches its peak. We tried getting the router back on  with wired connection and did a speedtest still the same as before but its a bit different. I got 14 ping, 19.54 mbps download and 6.47 upload. My ISP told me that he can't fix the issue with my router as it seems their modem is giving the right speed but not my router.

 

I decided to get a new one. Old router is asus N56U, new router is TP Link AC1750. So I run a speed test and I get 14-16 ping, 19-21mbps and still a stable upload speed. I played during the night I still get my ping goes up like crazy but it quickly goes down and the lag during playing is barely noticeable. The next day I tried playing during the afternoon and my ping goes back to what it is. After losing again because I just can't play, I check my speed test and it was at 18 ping 14mbps and same upload speed. This is giving me headache. I don't have this problem before. I don't know how to fix the issue. I'm also quite close to the router and the microwave is far away from me and the router. Pls help. I don't know what I'm supposed to do. with the new router I also did try doing a wired connection and it is still the same.

Make sure the firmware is 100% up to date on the router.

Ask for a new modem. If you are renting they will likely give you another refurb unit.

 

What provider are you with?

Also, if this is happening during peak times, make sure others are not using the internet as well. This can suck up bandwidth and cause you problems as well if there is not enough throughput available from your ISP on the connection.

they don't have it for rent. I'm not to sure if I can go and ask them for a new one as when we did the test on the modem with wired connection it was giving the right internet speed.

I'm basically the only one using the internet at home when I'm here as me and my roommate really is in different shifts. We don't even see each other. and he also has the same issue. we both are trying to figure out what's been wrong with the internet. We don't have this kind of issue before even during peak hours. I play games during the afternoon til night time, he plays during midnight and til morning and we both don't have any issues of ping latency being unstable.

If you both are having the same problems with the router wired and wireless and no specific issues are being found, try factory resetting the router and test it at 100% factory defaults. Then try setting things back up how you would set your network up and see if you can pin point if there is a configuration problem with the router.

Done that also. Tried that when we change the router. Didn't config anything and did a speed test still the same results. I'm out of idea already how to fix this problem of ours.

Did you outright buy the modem? If so you're probably fucked. They may offer a repair for $$$ ask to have a tech out to diagnose the issue.

Can you go and call their tech support and ask a tech out to diagnose the issue? Damn. I'm getting headaches just trying to figure out what went wrong with our internet.
