strange connection problem

I've been having trouble connecting to the internet. It just happened suddenly overnight. The ISP gave me a new router (Huawei SmartAX MT800) but the problem still exists.
The strange thing is that sometimes I can connect to the net and sometimes I can't. The ISP said that the problem was not at their end. During the times when I can't connect, I can't access the router also. When I ping 192.168.1.1, I get Request Timed Out.
What could be the issue ?
I don't know much about networking so if I didn't explain clearly please bear with me.
 
If You Cannot Log on to Your Router



These steps solve most of the problems with logging on to routers.

  1. Connect a computer and a router directly with an Ethernet cable, putting an end in one of the router's LAN ports. Check that both ends are secure.
  2. Check the Internet LED is lit. If it is not, troubleshoot the light status, as explained in the manual.
  3. Check that the LEDs for the ports with cables are lit. If they are not, try moving the cable to a different port. If there are still no lights, then troubleshoot the light status, as explained in the manual.
  4. Check the LED on the Ethernet adapter is lit. If it is not, then troubleshoot the adapter, do not continue with this document. If the Ethernet adapter was not made by NETGEAR, contact the adapter's maker.
  5. Select Start > Run. Type cmd. Type ping 192.168.1.1. If there is a message "Request timed out", type ping 192.168.0.1. If that also has a "Request timed out" message, then your computer is not making a connection to the router.
  6. Otherwise, your computer is connected to the router:
    • Make sure proxies are not enabled. If using Internet Explorer, select Tools > Internet Options > Connections > LAN Settings. Uncheck "Use a proxy server for your LAN....".
    • Delete offline contents. Select Tools > Internet Options > Delete Files. Select Delete all offline content, and click OK. (This is to clear any possible previous router log on page.)
    • Try accessing with a different computer, or with the Netscape browser, if you have it.
    • Delete cookies. WARNING. Do not do this if it's possible Web sites you visit need cookie information such as your logins and passwords.
  7. Power off the router, and power it back on again.
  8. If you still cannot log on to the router, then do a hard reset on the router.
  9. If you know how, check the computer's IP address and DHCP. The IP should be in the 192.168.0.x range, and DHCP should be enabled.

I can't ping 192.168.1.1. It looks like the computer is not making the connection to the router. The weird thing is that it doesn't stay that way. Sometimes, I can connect to the router and I can access the internet. After a while, it will suddenly stop working and I can't ping the router also.
My IP address is in 192.168.1.* range and DHCP is not enabled. My settings are not automatically assigned. My IP address, default gateway and dns server address have all been specified by my ISP.

well DHCP actually assigns IP addresses to each device on your network and you can tell the router what range of IPs it can assign to devices, genarally DHCP should be enabled unless your IP is assigned by your ISP,

Gateway - this is the way out of your LAN and is usually set to the IP of your router

DNS - Domain Name Server - these settings are usually assigned by your ISP as you say, but my net connection was unreliable when i used my ISPs DNS although all DNS does is (basically) convert a domain name (example.com, human readable) to an IP address (x.x.x.x, jiberish)

anyway, reset your router to factory defaults (usually a little button on the back of it) and reenter your ISP stuff

or uninstall it, perform a reset and reinstall it

BTW: don't forget to power cycle the router after the reset
 
I'm still having connection problems. When it does connect, the duration varies from a few hours to few minutes. The last time it connected, I had it for around 5 hours and then for the next few days, I had no connection at all.
I thought at first that it was some sort of loose connection, but I checked all the wires and connections to make sure that they were secure.
If something was wrong with my hardware, I wouldn't have been able to connect to the internet at all right ? What could be the issue for this weird behaviour ?
 
sounds to me it could be you have a bad NIC. I presume you've already tried another ethernet cable? you can buy a pci nic for about £5 if that, give that ago. 3com normally cheap and normally have a generic driver.

I take it you have a static something along the lines of:

IP: 192.168.1.10
Subnet: 255.255.255.0
Gateway:192.168.1.1

primary dns: 208.67.222.222
secondary dns: 208.67.220.220
 
Yes, I did check with another ethernet cable. Guess I'll try out another NIC.

Yea, the people who set up my connection keyed it in.
 
bad NIC :doh:, or maybe there's a firmware update from your ISP or your routers website?

you use OpenDNS too
 
yea i always use openDNS wan side of things because since i've used it never let me down, Isp dns is just a joke really. I don't use internal dns, i will just stick to ip's :)

:agree: whole heartedly

Comodo are vv reliable too but OpenDNS offer web customization too - sign up and customize when you get chance, v good for child profing net without using some kind of net-nanny software

sorry Ged we didn't intentially hijack your thread, it just kinda happened
 
192.168.x.x are RFC 1918 addresses, meaning they are private only, and are not used on the internet. This is the local connection between your PC and your router. If that's the case, it's definitely not your ISP. The NIC could be a problem, but I've also seen problems like this on Vista clients. Are you using Windows Vista?
