Hello i have some possible solutions they are:
1.Tuning TCP Settings.Gaming Tweak - Disable Nagle's algorithm
The tweak below allows for tweaking or disabling Nagle's alogrithm. Disabling "nagling" allows for very small packets to be transferred immediately without delay. Note that disabling Nagle's algorithm is only recommended for some games, and it may have negative impact on file transfers/throughput. The dafault state (Nagling enabled) improves performance by allowing several small packets to be combined together into a single, larger packet for more efficient transmission. While this improves overall performance and reduces TCP/IP overhead, it may briefly delay transmission of smaller packets. Keep in mind that disabling Nagle's algorithm may have some negative effect on file transfers, and can only help reduce delay in some games. To implement this tweak, in the registry editor (Start>Run>regedit) find:
This setting configures the maximum number of outstanding ACKs in Windows XP/2003/Vista/2008:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{NIC-id}
There will be multiple NIC interfaces listed there, for example: {1660430C-B14A-4AC2-8F83-B653E83E8297}. Find the correct one with your IP address listed. Under this {NIC-id} key, create a new DWORD value:
TcpAckFrequency=1 (DWORD value, 1=disable, 2=default, 2-n=send ACKs if outstanding ACKs before timed interval. Setting not present by default).
For gaming performance, recommended is 1 (disable). For pure throughput and data streaming, you can experiment with values over 2. If you try larger values, just make sure TcpAckFrequency*MTU is less than RWIN, since the sender may stop sending data if RWIN fills witout acknowledgement. Wifi performance may see a slight improvement with disabled TcpAckFrequency as well.
In the same location, add:
TCPNoDelay=1 (DWORD, not present by default, 0 to enable Nagle's algorithm, 1 to disable)
For Server Operating Systems that have Microsoft Message Queuing (MSMQ) installed, or if you have the MSMQ registry hive present, also add TCPNoDelay to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\Parameters
TCPNoDelay=1 (DWORD, not present by default, 0 to enable Nagle's algorithm, 1 to disable)
To configure the ACK interval timeout (only has effect if nagling is enabled), find the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{NIC-id}
TcpDelAckTicks=0 (DWORD value, not present by default interpreted as 2, 0=disable nagling, 1-6=100-600 ms). Note you can also set this to 1 to reduce the nagle effect from the default of 200ms without disabling it.
Notes:
Reportedly, the above gaming tweak (disabling nagle's algorithm) can reduce many MMOs like Diablo and WoW (World of Warcraft) latency by almost half!
XP/2003 needs hotfix or SP2 for it to work (MS KB 815230)
Vista needs hotfix or SP1 for it to work (MS KB 935458)

2.Changing MTU Value
Step 1: Find your MTU
From an elevated Command Prompt in Vista/Windows 7 or the same elevated Command Prompt in Windows 8 enter the following command:
netsh interface ipv4 show subinterfaces
You should get something like this
MTU MediaSenseState Bytes In Bytes Out Interface
---------- --------------- --------- --------- -------------
4294967295 1 0 13487914 Loopback Pseudo-Interface 1
1500 1 3734493902 282497358 Local Area Connection
If you are using Ethernet cable you will be looking for “Local Area Connection” or “Ethernet”. If you are using Wireless you will be looking for “Wireless Network Connection”. The MTU is in the first column.
Step 2: Find out what it should be
In the Command Prompt type:
ping
www.cantreachthissite.com -f -l 1472
The host name should be a site you can not reach, -f marks the packet as one that should not be fragmented the -l 1472 sets the size of the packet (1472 = Ethernet Default MTU – Packet Header, where the Ethernet Default MTU is 1500 and the Packet Header is 28 bytes)
If the packet can’t be sent because it would need to be fragmented you will get something similar to this:
Packet needs to be fragmented but DF set.
Keep trying lower packet sizes by 10 (i.e. -l 1460, 1450, 1440, etc.) until you get a successful ping request. Raise your packet sizes by one until you get a “Packet needs to be fragmented but DF set.”. The last successful value plus 28 will be your MTU value.
In my case a packet size of 1430 succeeds but 1431 fails, so 1430 + 28 = 1458.
Step 3: Set your MTU
Now you have identified the interface you need to change and the ideal MTU for you, now it is time to make the change. Again from an elevated Command Prompt type the following replacing my MTU of 1458 with your own value:
netsh interface ipv4 set subinterface "Local Area Connection" mtu=1458 store=persistent
Or if you are using a Wireless connection:
netsh interface ipv4 set subinterface "Wireless Network Connection" mtu=1458 store=persistent
If all has gone well you should have a perfectly working internet connection.
3.Using Cfosspeed and tuning it for low latency also after installing give lol exe highest priority.
4.if you see an option like multimedia/gaming improvement in advanced tab of your network interface controller at device manager enable it and try.
5.Enable direct cache access and tcp chimney offload from cmd with these commands
netsh int tcp set global dca=enabled
netsh int tcp set global chimney=enabled
