  1. So looking at the results of the ping test, the +PDV value indicates the instability in your ping to the various locations it tests. This shows there is some significant instability in your internet connection, and because of the number of locations tested, we can be pretty sure this is down to your ISP. When looking at the 3 traceroutes you performed, you can see that hop 2 has a relatively steady ping and doesn't change much across the 3 tests or the 3 traceroutes. However, hops 3 and 4 have got a significantly higher fluctuation and go as high as 160ms on the final traceroute. This suggests to me that your ISP is suffering from congestion on their local network, and it may be worth contacting them. I am also on DSL, although in the UK, so our DSL tech is slightly more advanced. I'm also using a separate modem and router, one being the Huawei HG612 (which was provided by our national infrastructure provider BT Openreach) and the other being a Ubiquiti EdgeMAX EdgeRouter X-SFP. In other words, my gear is quite high grade as well. In terms of the ping test, here is mine as a comparison: I did this over wi-fi as well for context. And here are my traceroutes: In terms of your router, even though I don't think it is an issue, it is always good to upgrade it to something more recent if you've had it for a while. My current recommendation is Amplifi if you want something simple to use, or if you want more control, Synology's products are excellent and have a ton of functionality.
  2. I just did an ARIN lookup at each hop based on his given traceroute. Virginia is the office registry for the ISP PCCW Global, not the location of the PoP. The same can be said for the IP for Riot Networks, again, an office location. Riot makes use of public cloud and private data centres, so it isn't possible to be absolutely sure of where he is being routed. The IP of the first hit onto Riot's network is for the Seattle internet exchange, so that trumps everything you said regarding the route. My conclusion still stands that the PCCW network is routing him to Seattle before entering Riot's network, despite them having links to both Los Angeles and Chicago via Dallas significantly earlier in the route.
  3. I agree here that it is highly unlikely a user with a consumer grade load balancing router would manage to cause a routing loop. If it was enterprise gear then yes maybe, but not with consumer grade.
  4. TTL for DNS is the number of seconds a recursive DNS resolver or DNS client should store a record in its cache. You are thinking of TTL from a routing perspective here. Can you elaborate on how you came to this conclusion? I am fully aware of what BGP is and how it works. I study it as part of my degree. The reason I said routing error is because BGP isn't the only protocol used. When an ISP has a peering partner a lot of the time the routing to the final destination may be done internally using a different protocol such as OSPF or similar, some of which as you well know use factors other than latency to decide the optimum route.
  5. From what I can tell TEC appears to use AT&T as a peering provider to connect to the wider internet, so the issue doesn't lie there. I would suggest the issue maybe lies with any filtering or ACLs that the company may have, possibly for parental controls or similar services. I think it would be best to contact them and ask. Just while I'm on the topic, the idea of 24/7 customer service based locally is actually quite nice from an ISP.
  6. Some people in this thread seem to be overlooking the fact that this is a fibre optic connection, which means an ONT has to be used somewhere. In this case the Huawei unit is the ONT being used, so we can't actually remove that, we have to augment it. My suggestion would be to disable the wifi on the Huawei and to buy an 802.11ac wave 2 access point to improve the wifi speeds. You won't be able to actually replace the Huawei unit as it is hardwired in.
  7. The way to do this would probably be VLANs with separate gateways (ISP connections) but this would be very complex to do and require enterprise-grade switches and routers.
  8. What country are you in Niraj? It sounds like they are using ADSL2+, in which case with 5Mbps you are looking at 40-50ms ping I would suggest at the least. As juan said, there is no point in changing ISP if they are both using the same infrastructure (copper-based ADSL2+) so I would hold out for a fibre based connection if you haven't already got one available.
  9. My suggestion is to check out Amplifi. The gear is built by Ubiquiti networks and apart from the management software is basically enterprise grade. I use some of their enterprise gear and it is really good.
  10. I use Ubiquiti gear in my house, specifically the AP-AC-LR. If you're living in an apartment, you are going to be dealing with a lot of network congestion on the air, so I would suggest first using the Wifiman app from Ubiquiti to see what wifi channels your neighbours are using and trying to set your channel to the least congested. If this still doesn't fix your issues, my suggestion would be a small Ubiquiti Unifi network. A pair of AP-AC will probably do the job for your apartment, but you need to make sure they are both wired so that you aren't having to deal with the airtime congestion due to multiple wifi networks. Here is a great guide from Troy Hunt on how to plan, install and set up a unifi network from scratch:
  11. I have some concerns both about the ISP router and the Linksys router. What model is it from Linksys? With a gigabit internet connection and 50 clients, I would be very worried about the router being overwhelmed, to the point where changing a connection type won't improve it.
  12. Are you on AT&T or a different provider? Are you tethering or do you have a fixed line such as DSL or cable?
  13. Yeah, this looks like someone used you for DNS amplification. What you should do is just disable the answering of ANY requests altogether. That is now industry standard I believe for all public facing DNS servers, as the ANY query type was used specifically for DNS amplification because it provides the largest data volume. Cloudflare disabled it in 2014 to basically 0 effect on their legitimate customers: https://blog.cloudflare.com/deprecating-dns-any-meta-query-type/
  14. I have a couple of questions regarding this. I used to help troubleshoot on a UK DSL forum and issues like this crop up all the time. Are you the only person on the network? Is anyone else in your house using the internet when you are doing the speed test? Could you go to this link (https://www.dslchecker.bt.com/) type in your landline telephone number and tell me the speeds listed for Download next to VSDL Range A (Clean) and VDSL Range B (Impacted)? Have you tried restarting the router? Do you have just the Sky Hub or do you have another box as well with a BT logo on it? As others have said, as frustrating as it will be with Sky (I know their reps are bad, but just get through it), you need to ring them and get them to do tests from their end of the system. I agree with others that this is likely to do with your router but there may be other factors in play here.
  15. In addition to the questions listed above, a couple of others. Have you tried replacing the cable between your computer and modem/router? What is your connection type? (Cable, DSL, Fibre to the home, LTE/4G, etc.) Are you using a single unit (modem and router in one box) or do you have a separate modem and router (two boxes linked together)? What game is it that is affected? Are there any other games that are affected as well? Are you using the Killer Control Center software included with your motherboard? What country/region are you in? To assist in diagnosing issues, could you perform a traceroute using this guide: https://support.cloudflare.com/hc/en-us/articles/200169336-How-do-I-run-a-traceroute- Could you please do this to the following addresses: 1.1.1.1 8.8.8.8 147.135.0.102 Please provide us with the results of this. Could you then also go to this link: https://www.dslreports.com/tools/pingtest Please perform the ping test using the large start button for approximately 1 minute and post a screenshot of the result. This and the previous test will help us diagnose if the issue is within your network or not. The last is just to do a standard speed test at https://www.speedtest.net and post the result for us.
